Photographic composition is the first step, although photographic composition rules are not dead, but understanding some of the primary composition can avoid mistakes when watching the good work, you can understand why such a film photographer, is also helpful for the improvement of their own . In this paper, an introduction to photographic composition, although this article focuses on landscape photography as long as the composition, but the view of a composition is the most complex, so after these rules to master, many can also be applied to other types of photography on.

1. Attractive scenery

Composition first step is to find an attractive landscape. Photography is not simply pick up the camera shutter, before pressing the shutter, you have to ask yourself, What attracted you to the scene where? Is the color? Clouds? Reflection? Or sunset? Identified the main, the next step is to show how it. Typically, the subject should be of sufficient size to eye-catching.battery for Dell Vostro 1000 Subject is too small, not a subject, this time is necessary to use a long focal point, or to deal with a late cut.

Between the singular phenomenon of nature is very easy to become an attractive subject. It was a rainy evening, I noticed that there is no place in Western sunset clouds, so I guess there might be a rainbow, then went to the park, took the rare scene.

2. To avoid the center

Beginner photography are the most common mistake is the most attractive landscape on the middle. Indeed, in the middle of the scene is most likely to attract attention, but a good photo should be in attracting the reader’s attention, it can guide the reader’s attention to other places to go. If, attractive objects on the middle, it is easy to make people focus only on that object, and so the screen becomes dull. Also, try not to make horizontal lines on the screen in the middle, because that would easily lead to major and minor is not obvious, do not know the key is to express the sky or the ground. But sometimes in the sky and the ground is equally important, I will put the horizon in the middle.

3. Composition rule of thirds

Since the center to avoid, we must know the so-called “rule of thirds” (rule of the thirds), also known as “Golden” and “Nine Palace Grid” … … “The rule of thirds” is the basic rules of composition, meaningDell Inspiron Mini 9 battery : the screen horizontally by 1 / 3, 2 / 3 position draw two horizontal lines, vertical direction by 1 / 3, 2 / 3 position draw two vertical lines, then the scenery as much as possible on the intersection of the position.

4. Prospects

Because we have two eyes, so we see the world is three-dimensional, but the photos are two-dimensional, two-dimensional to three-dimensional expression of the picture is not an easy thing. Our brain tells us: a large object is relatively recent, small objects are more distant, so the size of the object in the picture by contrast, can feel the distance. In the world of photography, telephoto shooting scene is the “compression” together, and wide-angle effect is a reduced distance of the scene, gave people a distance. So,CASIO np-60 battery on this occasion, we generally use the wide-angle lens.

5. Simple

Some people say that photography is a “subtraction”, that is irrelevant to the subject on the screen with all the best to remove the object, the simpler the better. I agree with this view, especially for beginners, the composition is simple and should start.

6. Into line

“Import line” by definition is to lead the reader’s eye into the picture of the path, into line is a path, a bridge, a river … … or any object into the screen. Typically, the import line should lead the reader to picture the most attractive place, the reader should try to avoid out of the picture outside. Import line is part of the picture, so the import line should also be attractive in itself, but also other parts of the screen should be coordinated.

7. Sky

In landscape photography, the sky is a very important part of the sky is often a major part of the composition, and natural beauty of many natural thought is enough to shock people. So, good photography enthusiasts, should always pay attention to weather changes, so we will summarize some law of nature, for example, is the most beautiful sunset after the rain,HP Compaq Business Notebook nx8220 laptop battery the rain if the sun, you will see the rainbow and so on … …

8. Texture

All things have a texture, a beautiful texture can be easily attracted to people, talked about the beautiful texture of each, the total texture reminds me of the desert, but unfortunately I had a chance to shoot the desert.

9. Negative space (negative space)

What is negative space? Simply put, negative space is the space between objects and negative space in the photo is usually the performance of an isolated way.

10. Reference

Photographs of the scenery alone, and sometimes it is difficult to determine the actual size of the object, and through our familiar frame of reference, comparison later, we can “feel” to the size of the scene.price of Compaq Presario v6000 battery This reference is often used to form the magnificent nature, spectacular.

Summary:

Whatever the rule, so the rules are intended to make the picture look “balanced”, as to what to succeed “balance” can be understood: the screen is all the objects are the “weight”, and by reasonable arrangements to distribute them to connect or get a more balanced picture, no matter what rules to use, good photos always look the whole picture balance and harmony. There is a saying: the rules are made to be broken, all the rules are not dead, for example: when the film reflection lake, and sometimes inevitably need to level in the middle.

 
Find hidden in the QQ “ghost”
If you have friend somehow can send you some files such as “Video Girl” links to your conveyor virus, do not blame your friends to deliberately make trouble because he is also a victim, his QQ by the virus attacks, automatically radiated toxic. Vanguard of anti-crime issue from Suzhou, Wang Qiang is necessary to ferret out hidden in the QQ “ghost”, but also a clean and Netsky.
Anti-crime Vanguard: Wang Qiang City: Suzhou
Using the system: Windows XP SP2 descriptions of the symptoms
Shortly after the Internet today, received a number of QQ friends rave information, which makes me very puzzled. One asked to know, but they have received my QQ sent the information of all kinds of mess with the virus file, and also with the news. And the name of the virus file also varied, and made me very puzzled, do not QQ stolen? Then re-apply a QQ number, together with a friend, and within three minutes, it received the request to receive the file. And with virus files. Is my QQ virus attacks? Think of a few days to install a downloaded program, an error window pop up. Was not feel right, so an immediate anti-virus, but did not find any virus, it now appears certain is this program in “trouble”.
Find the clues to open the Task Manager to view, find a file called “the Rundll32.exe process. Common applications rarely call the Rundll32.exe, the most commonly used Rundll32.exe that some rogue software, or Trojan backdoor, It seems that the Rundll32.exe most suspicious.HP Probook 4720s battery
Click the “Start” menu, search for files or folders “command, and then find the Rundll32.exe” keyword. The results also found in the system directory of the SYSTEM and SYSTEM32 folder Rundll32.exe trace. By resolution of the file icon, I soon found a suspicious file, because fake Rundll32.exe actually to WINRAR icon (Figure 1).
Figure 1 find a suspicious file, I began to prepare to find the start of the virus. Run the Registry Editor, the same search for “the Rundll32.exe” keyword, the results did not find a suspicious startup items. Since there is no suspicious startup items, I decided to remove the virus, restart the system and then check the system processes, and did not find the Rundll32.exe this process, QQ is good news to friends, when I start the “hateful” the process of appeared. Rid of the virus
It seems that the QQ virus did not imagine so simple, it must be a file protection technology, so that when a file is deleted, other documents will soon generate a Rundll32.exe file a copy of. Just observation and the previous inspection, I think this QQ virus not start with the system to start, followed by the start of QQ. QQ installation directory then immediately came to check and then find a WINRAR files as icons name “TIMPlatform.exe”, in addition also found that a named “TIMP1atform.exe (Note 1 is not L) file (Figure 2).
Figure from 2 TIMPlatform.exe (note that not 1) use QQ and TM external application development interface management procedures, belonging to the QQ 2004 edition,HP EliteBook 2760P battery to become an integral part of the underlying core modules. View of the file attributes, found “TIMP1atform.exe” This document is developed by Tencent. It seems this QQ viruses changed its name to be formal TIMPlatform.exe the “TIMP1atform.exe, the virus itself instead of QQ in the program. Order to completely remove the virus, the system by the time properties of the system search function “TIMPlatform.exe search results also found that the two documents. The first end the Rundll32.exe this process, and then just found out that the two documents and the Rundll32.exe, TIMPlatform.exe removed. Then modified virus TIMP1atform.exe “restore” TIMPlatform.exe.
Detection, the system again and found the association of the registry Chinese and executable files to be changed immediately to repair it through the Super Rabbit, the ultimate success of the virus is completely cleared from the system.Thinkpad 600 Battery
With the gradual increase of QQ users, QQ has also become more and more breeding grounds for viruses. In fact, a little some programming capabilities of the user will be able to write a similar virus, even if it can not write can transform someone else to write the virus to spread. It also makes this type of virus size is getting smaller and smaller, more efficient, endless variety of new viruses or variants, it makes a lot of anti-virus software now struggling to cope with, it is difficult for killing the first time.
Wang Qiang in checking suspicious files, first of all proceed from the system directory, did not completely remove the virus, check the other directory, and ultimately successfully cleared the virus itself. We face the hazards of this virus can also use anti-virus software manufacturers to develop Zhuanshagongju for killing. QQ Thief killing tools QQKAV, QQ tail Zhuanshagongju (Figure 3), can easily deal with these common QQ virus.

Easy access to elegant photographs hazy rain effect, because the rain reflective, bright image scene hazy distance, the picture of the scene, the tone has caused bias, do not

have a flavor.
Rain exposure shot
Light rain change is complex, sometimes cloudy, like the brightness is very low, light sense of direction is not clear, and sometimes the rain scene brightness and high

exposure between the two many times can vary. So when shooting, it is best to use light meter metering.
Rainy day shoot, most people take to reduce exposure method, which is normal to reduce a file to the exposure half of a file, which will help improve the image contrast.

Because the water droplets, water droplets, water stains,battery for IBM ThinkPad R60 almost transparent, in dark environments susceptible to excessive loss of light “water” texture. Rainy days, there

will be overexposed film often the case, the rain scene contrast is small, will contrast less overexposed, then shoot a picture is gray.
Shooting shutter speed when the rain scene
Shooting scene when the rain is not too high shutter speed, because speed will rain Ning Zhu, forming a small point, but not the feeling of rain. If you use the shutter speed

is too slow, the rain will pull strips,ACER Aspire 5738G laptop battery the effect is not good. Generally use 1 / 30 seconds to 1 / 60 second speed is good, then the shutter speed is not high, can emphasize

the dynamic water landing. We can refer to a small fast slow rain, rain rule try to shoot a high speed.
Shooting distance between the lens and the rain
Rain King shooting, we should pay attention to the lens and the distance between the raindrops. Rain away from the camera too close when a small drop of rain will cover the

distant landscape. Of course, sometimes deliberately need for such special effects. The camera can not pay attention to the rain, nor rain splash to make the lens. Umbrella

cover or generally available to the camera in a plastic bag, the exposed parts of the lens and viewfinder.
Rain King should take note:
1, shoot rain scenes, the dark background of bright rain can come out,JVC bn-v114 Replacement battery not to the sky or light the scene as background.
2, splashes of rain fell on the water in waves is a scene in the rain a good shooting point.
3, in the room, as to the performance of the outdoor shower scene through the window when the window can be coated with a thin outside layer of oil, so easy to hang on the

glass drops, rendering the atmosphere of the rain.
4, beat the rain the night, because the light reflection and the reflection of the ground surface, will make the picture looked very lively. Dell Inspiron 9400 Replacement batteryIn particular, the use of color

film when shooting color effects rainy night richer than the average night.

A digital camera macro friends will certainly take photos, shoot macro pictures must ultimately take plants and flowers, which almost every player has a digital camera will do things, but watching other people online who shot the beautiful plants and flowers can be taken out of their photos is not so beautiful and moving, it felt like nothing fresh to mention it. In fact, macro creation with a digital camera there are inherent advantages, and many new digital cameras in the macro aspects of strengthening the function of many familiar products, Macro 6cm recently in the following shooting distance, which as we shot Floral hastily provides great convenience,battery for dell xps m1730 the following four elements of our theory by improving shooting skills under the flowers.

Four elements:

A good flower picture must have the following four elements: a clear theme, the perfect light, simple composition, harmonious colors. Both the independent existence of the four elements, but also an inseparable merging together to support a pair of works. When photographing flowers, can grasp and handle the four elements are key to success.

First, a clear theme

Flowers is different from other landscape photography, landscape not only in the famous tourist attraction, places of interest at home and abroad to be able to shoot good work, as long as students around the flowers you carefully close observation, you will find film of the finish, photo of the different subjects on the side. Such as clear after the rain,price of Dell Vostro 1510 battery snow scenery, spring style is to shoot the object, whether in the residential area, mountain fields, or outside the park, there are many beautiful plants and flowers moving in the face of exhibits, which requires we went to carefully dig.

Photographing flowers, through light, composition, color contrast, depth of field control and other technical means to highlight the most interesting places. The minimum requirement is to take the best part of the film clear. For example in Figure 2 where this little flower is the flower most touching, but very small flower flower thick, especially vulnerable to the impact of wind and respiratory gases, the author adopted the manual focus, focal length of the location of choice for the 2CM, the into the smallest aperture to ensure maximum depth of field. Clear the way is very difficult to shoot flowers, one from a bad master manual focus, a clear focus in terms of liquid crystal displays, and can not shoot out clear. Second, such a small flower generally low, not easy to use tripod. Third, the moment you press the shutter, there can be any sign of trouble. In addition to repeatedly shoot, you can also use multi-shot, or surrounded by shooting, try several times to have access to the pictures.

Second, the perfect light

For Flowers, the light is essential. Natural light conditions,JVC bn-vf707 Replacement battery scattering light and the backlight is easy to shoot good results. Scattering contrast between soft and delicate little flowers, the texture and feel able to show it; backlight to outline the contours of the texture of thin translucent flowers and moving, and can hide the clutter in the background. In strong sunlight, using light and side light along, not easy to take good flower.

Flowers after the rain in the morning to shoot a good time, clean and blooming flowers, fresh air, perspective is good. Under the conditions of the scattered light shooting flowers, should also be careful to grasp the point of light, light and side light effects along a big difference, to observe carefully and conscientiously use.

Comes to light, can not talk about the exposure of the grasp. Some friends because digital pictures in graphics software be free to adjust the effect, while ignoring the issue of exposure when shooting. In actual fact, of course, later adjusted to improve shooting enough. However, the post-shot exposure adjustment and accurate picture of the texture and color saturation difference is relatively large. So when shooting, must pay attention to the exposure problem. Functions do not have manual exposure camera, be sure to make good use of exposure compensation function, the background brightness is high, generally +0. 7 or +1;HP Compaq Business Notebook NX6320 laptop battery background brightness is low, generally -0.3 or -1. Compensation coefficient depends on the specific background and to determine the difference between the brightness of flowers. Camera with manual exposure capabilities, to observe the shooting environment, find reflection rate of 18% or close to the reference object as metering. Short pre-shoot, we must attach importance to the accuracy of the exposure.

Third, the simple composition

In all subjects in photography, flower photography is a composition of one of the most demanding subjects. Composition of the basic requirements is to highlight and beautify the main theme is the most difficult to be a problem is to follow. For example Jiugongge rule, the entire screen divided by Tic Tac Toe, the points of interest into an intersection. May sometimes not be fully in accordance with this rule arrangement. So many artists say that the composition is not fixed, by learning from art, film, television and other sister arts, is an effective way to improve the level of composition.

The composition of flowers in the shooting,HP Compaq Business Notebook 6710b Replacement battery how to not use or interfere with the theme of the scene to remove to highlight the theme of simple picture is indeed one of the most headaches. Main method is to use depth of field to blur out objects in clutter, the theme of ensuring a clear case, as far as possible with large aperture; or mobile themes and backgrounds.

Fourth, the color harmony

Flower color and shape is to win, flowers, photography should be noted that the color processing. A floral images, there must be harmonious colors, not haphazard. Each flower has its own color characteristics, according to different themes, different lighting conditions and different background colors to be used to determine their own. Red and green, though dazzling, but it handled well, but also beautiful pleasing; understatement, though plain, can be used properly, but also elegant high juvenile, it is an attraction in itself. A floral photography, gotta have a main color, both in cold or warm tone tune based primarily,price of HP Pavilion zv5000 battery if used properly, can “total cash Yihe affordable.”

Many digital cameras are suitable for macro photography, of course, the key lies with you to observe the students to explore more ideas and more, these tiny plants and flowers allows us to experience the natural beauty and pleasures of life.

The lens is very important

For landscape photography, the lens is the most decisive photographic tool.

The best course is to cover all the lens focal length configuration, both zoom and fixed focus, aperture the bigger the better. But the reality is often either can not afford such costs, can not carry so many shots, so we still have to be trade-offs. The choice is mainly based on their habits and preferences of photography, taking into account the purchasing power of their own physical fitness and carry equipment.

1. Telephoto and wide-angle

In one view, wide angle for shooting scenery,battery for TOSHIBA PA3457U-1BRS telephoto for portraits. But in fact, both the need for wide-angle landscape photography, but also need to telephoto. Compared to the wide-angle lens was great symphony conductor, the telephoto compared to instrumental solo performer. This argument though not necessarily, but more image.

By definition, wide-angle lens in landscape photography that can accommodate a wider range of information, so more suitable for large magnificent scene. Compared to a telephoto lens from the clutter of the scene cut out the most interesting content.

The theme of landscape photography is sometimes composed of a single element, sometimes consisting of many elements. In a single element, as long as the perspective of a variety of lenses to allow,Dell Inspiron 6400 laptop battery can be a very good performance of the theme, although the effect may be completely the same performance.

A lot of very successful films often have a lot of landscape photography elements. In the case of many elements, sometimes need a wide angle to accommodate them in, sometimes need to compress the perspective of unrelated elements added together. At this time, wide-angle lens and telephoto lens elements in the organization have very different photographic functions, they can not replace each other.

In practice, the use of wide-angle lens is often more difficult, especially in view of the lens greater than 24mm. Because it contains too much information, photos, the theme of the course in the organization vulnerable to a variety of problems, such as too many distracting elements, organizational disorder screen cluttered and so on. Perspective distortion of wide-angle lens itself is often difficult to control the side effects.

For starters, perhaps more telephoto ability to help develop observation and easier to shoot the pictures, and record wide-angle may be a better tool, a good number of films is more difficult. In short,price of ACER Aspire One battery telephoto and wide-angle landscape photography are not neglected, a view equivalent to 135 24 ~ 105mm zoom lens camera can be a good starting point.

Similar high-end Fuji S9500 that a fixed lens digital camera provides a focal length of near perfect choice, it’s manual zoom lens covers the focal length of 28 ~ 300mm section, whether it is grand spectacle, or the details of the distance pieces can be beautiful easy access.

2. Large aperture and fixed focus

In one view, the wide-angle lens landscape photography is not necessary to stress that a large aperture. Although we more often landscape photography you need to shrink the aperture, but does not mean that a large aperture lens is not important. A lot of dark room and night lighting conditions, especially in the human environment of landscape photography, a tripod is helpless, a large aperture lens is record-specific light environment of the weapon. Therefore, f2.8 to f4 large aperture zoom lens than the more widely applicable environment.

However, it is difficult to achieve f1.x zoom lens aperture,Sony VGP-BPS2 laptop battery f2.8 is the general to the limit. Therefore, many digital SLR users will choose a large aperture prime lens to meet the specific lighting conditions. The difference is that with the portrait photography, scenery photographer at this time will tend to choose wide-angle fixed focus lens, such as 24mm, 28mm, 35mm, in the use of large aperture still has enough depth of field, and avoid too much background blur. Large aperture wide-angle fixed focus lens has a sufficient under normal circumstances.

3. The use of polarization microscopy

Many landscape photographers are accustomed to twisting in front of the camera has been a polarizing microscope, especially when the light is better. Polarizer can eliminate the air diffuse light and increase the degree of air permeability, so that more blue sky, you can eliminate some of those annoying reflective surface, eliminating the formation of surface reflectance of high spot of light to improve the color saturation .

In the sun, polarized light microscope is almost indispensable tool for landscape photography. Polarizer in the other use is gray density as a mirror, can reduce the exposure time of at least 2 files.battery for Dell XPS M1530 Shooting waterfalls, streams, and other topics, the long exposure blur effect can be obtained, and a polarizer can help you in case of strong light to 2 times longer exposure time, two twisted polarizer you can extend more than 4 times.

2 pieces of glass polarizer is composed of relatively thick, wide-angle lens on the vulnerable in the dark corners. Therefore, it should be specially equipped for the wide-angle lens thin polarizer.

Purchase at the end of 2008, Seagate 7200.battery for Toshiba PA3384U-1BAS battery
11 500GB drives use occasionally without undue loss of response, the system stuck a few seconds (time ranges), I did not care, that is the system reasons did not worry about, but two months later day, there has been a blue screen of death situation, restart the computer after the hard power, rotation, but can not be detected by the motherboard. Data lost, ask around friends have different opinions, some people say I used improperly, some people say it is my poor power quality (but my power supply is a serious domestic manufacturers licensed 450W), one may Seagate hard “invisible injury”.
Colleagues found similar symptoms in the days following, but the model is slightly different from his hard disk is 7200.11 640GB product. I think this is no coincidence, therefore please CFan detective firm to help me to investigate more thoroughly.

After receiving the case, Detective Alpha case analysis:
Doubt one of the hard drive under normal use conditions, high temperature or vibration will cause hard disk failure rate increased significantly, but only limited to the hard disk damage,Dell Inspiron 700M laptop battery loss of data, power does not recognize is almost impossible happened.
Doubt the two power supply problems are likely to lead to hard disk unusual culprit, but taking into account the reported use 450W authentic licensed power, and there are similar cases in the same period of time …
In any case, our first two points above questions to investigate, if the individual phenomenon to analyze the cause of the malfunction, but if it is the vendor’s “invisible injury” is not a small thing.

Stores unannounced visits to Make note of
“Boss, give me to block 500GB hard drive, you recommend a brand!”
“I recommend that you Western Digital 6400AAKS, compared to the 500GB price gap is small, the performance is very good, how you look like?”
Western Digital ah? I personally like Seagate, Seagate 7200.11 500GB you stock?
“… Be honest and you talk, Seagate’s failure rates are very high, the alleged problem with the firmware, I have temporarily stop the purchase, after all, do not want to take the risk.”
“Oh, like this, I still look to buy it, Xiela!
“There is need to keep you well!”

Official rhetoric
In the store unannounced visits, visits to businesses to reflect the Seagate hard drive failure rates high, but vague, can not make it clear why, it seems that this problem is not the case, so we have issues related to Seagate’s domestic distributor Jianda Grand stakeholders asked the official answer is: “a very small number of Seagate Barracuda 7200.HP Pavilion N5195 battery11 hard drive found a firmware issue that led to the on / off the power may not be able to access the data returned through the analysis of field data, can determine The risk is very low, Seagate believes that the affected hard disk can be used as usual, but Seagate will provide free firmware upgrade (service) “.

Forensics summary
The official version seems to matter only a small BUG, ??not a big problem, but the results obtained with the store a very high failure rates but the opposite. Following the investigation of a number of forums, we found that the breadth of the incident magnitude of far more than the results of the survey. Production in December 2008, the Barracuda 7200.11, include DiamondMax 22, 21 models of the series of desktop hard drive The Barracuda ES.2 SATA firmware defect exists (even the detective firm West students in the move). The official inquiry is not has no effect, at least we get a solution – firmware refresh.dell ac adapter

Solution
First step to determine the hard disk model, click on the Start menu and typing “devmgmt.msc” to open the Device Manager in the running. Expand “Disk Drives” branch,you can see the hard disk model. Determine whether their hard drive requires a firmware update.
In the second step, download the firmware to burn to CD or make a floppy disk,Thinkpad R52 Battery the boot of the system (firmware download list: .
The third step is to boot from the CD into dos, run flash.bat, and select the model, follow the prompts to complete the upgrade operation.

With scientific and technological progress and development, digital video cameras are constantly engaged in innovation and improvement. Ask for the readers, the paper briefly several digital camcorders using the new technology.

First, electronic image stabilization technology

High-end professional video cameras use more optical anti-shake system, which is shaken by a video camera light sensor to detect the prism, the use of floating lens elements of the stability of the results.battery for SONY NP-FH100 The optical image stabilization system, the high price and bulky, so hard to use a small digital video camera. For small digital video camera manufacturers have opened up a new electronic image stabilization technology. Early electronic image stabilization technology is the CCD output jitter of the video signal, stored in the video field memory, and then change the memory address, new address to re-read by the video signal, thus eliminating the image jitter.ACER Aspire 5735Z Battery This memory type of electronic image stabilization technology, memory size drawback is the large field, it is not appropriate for small palm-sized camcorder. Electronic image stabilization system uses a new generation of large CCD optical coupling devices, such as enlarging the area to increase the scanning line, and then take the middle part of the main scan image, the other anti-shake around the image is produced as a motion space, so as to achieve a good image stabilization effect. Some are also used to detect signals from the video images of the jitter, in accordance with the elimination of jitter to control the CCD scan range, to obtain a stable image.

Second, the zoom microphone technology

Photographers have such experience, when the lens from the distant past into a figure is difficult to pack to take to the loud, clear voice. This is because most non-professional cameras are using a relatively large angle, then the microphone. Professional video camera from the video camera interview with the characters than the distance,price of PANASONIC cga-du21 battery they often point to the microphone from the video camera connected, but the price of several thousand points the microphone, apparently low-grade video camera configuration uneconomical.

Therefore, camera manufacturers have introduced some new small video camera to use the zoom microphone technology. Zoom microphone works Simply put, that is, with the zoom lens cameras installed on the synchronization point of the variable width of the microphones pick up sound, this mic with the camera lens into the near distance, while controlling the microphone wide range of sounds picked up by the narrow, more focused recording distant sound of a single target, as if the voice of a target distance from the light to the ring, it seems that the photographer close to the target gradually.

Third, the backlight compensation shooting

Shooting in the snow, the beach in bright sunlight shooting in the background wearing a shiny silk or synthetic fiber sewn clothing figures of the shooting, and shooting to the background behind the bright light or when shooting people, professional camera Teachers often use manual aperture adjustment, auto iris shot in the backlight can not make a clear contrast of the right of the main characters. Taking into account the film’s fast, easy operation, many new cameras designed and installed the backlight compensation function. Backlight compensation is usually shot in the video camera set BLC (BACK LIGHT) key to start the shooting in backlit keys larger than normal to control the aperture, so that in the backlight of the characters, scenery clear, bright.

Fourth, infrared night vision technology

Environment in the whole shoot dark,SONY PCGA-BP2NX battery eyes can not tell who shot the scene with the character, professional camera batteries often have to bring the students with the flash. Dark environment to facilitate the shooting, the camera manufacturers have to infrared radiation technology applications in the video machine. Camcorder in dim environment at the chance to launch out of a red line of the beam to illuminate the scene and characters, so that cameras capture clearer pictures. Of course, image quality is not perfect, and some video cameras with the use of slow shutter switch, image quality will improve more.

Five, black and black compression expansion

This camera technology is the only increase black extension detail and dark gray levels, without affecting the light at the image; and black compression is only to improve the contrast of the dark, without affecting the light at the image contrast. Compression black contrast only 40% lower than the signal level impact,TOSHIBA PA3479U-1BRS laptop battery and high contrast of 40% for the signal level had no effect. As digital video cameras using digital signal processing LSI DPS, so the black for the black expansion and compression of the parts operation accurately, fast and effective. Taking into account the digital television signal quantization noise, black expansion circuit for increasing the number of cameras increase the quantization bits better.

VI, CCD’s defect compensation

Appear in the screen shot of small needle-like dark spots, white spots, or the vertical bright line (IT-type CCD has been expressed in the entire field of bright lines, FIT type CCD is common for the half-light line), in general, is Because the defects caused by CCD.

Whether a digital camera or digital video cameras are used in hopes photosensitive optoelectronic device CCD defect better, but the CCD manufacturing process is very difficult to completely defect, CCD pixels in the course of the individual defect caused damage to failure are inevitable. Therefore, the defect compensation for CCD operation for us.APPLE A1189 battery The CCD digital video camera called the defect compensation circuit LPC (Leaking Pixel Correction). CCD video camera in it and the surrounding pixels with each pixel in the other two to compare the corresponding pixels, a pixel signal when that failed, they use instead of the average of surrounding pixels, thus overcoming the image quality of CCD defects degradation.

Professional grade video cameras for the factory detected CCD defects, by identifying the location, and then written to a ROM (usually on the ROM component of the NR-board CCD camera), and finally read out by controlling the CCD clock shield out defects.

Often by the laser beam according to the CCD light-sensitive device to generate defects, so the camcorder used, especially in order to render the atmosphere and stage performances by shaking when the laser shot, the filter should be installed to prevent a particular video Machine CCD defect caused burns.

And under normal circumstances the different macro photography, this technique is the use of said digital camera macro mode close portrait photo shoot, this distance is not commonly referred to as 1-15CM, but the 40-80CM.

Many consumer digital cameras to digital cameras,battery for Dell Inspiron 1545 players will be caused by imaging the depth of field size too small, ineffective virtual background issues and problems. In fact, the proper use of the digital camera macro feature can effectively solve the problem.

“Proximity” recording principle:

“Close” Photography is usually achieved using the macro photography mode, for example, some digital camera in macro mode can 4CM-70CM clear imaging of objects from the range. Compared with ordinary film,price of ACER Aspire 5315 battery “close” photography as near the subject from the lens, less depth of field can get a better background blur effects. When using the macro mode to “close” facial close-up portraits, often can play a virtual background, highlighting the main role. The following two simple applications first portrait is taken, the second application macro mode shooting.

Compared before and after the two in front of a background blur is not obvious, use the macro mode pictures taken bokeh effect is obvious. In the portrait shot using macro mode,price of TOSHIBA PA3465U-1BRS battery can often play a virtual background, highlighting the main role.

Digital camera macro mode “close” we should pay attention when shooting portraits points:

1. The best all-manual mode or aperture priority mode, aperture set as large as possible, such as F2.8, f3.5 …. Because the camera in automatic or program settings, as if lit would have to use a smaller aperture such as f5.6, f8 and so on.

2. Note that the choice of focus, Macro generally shallow depth of field, such as focus improper selection (before or after too), will affect the image quality is generally recommended to focus on the subject’s eyes.

3. If you get too close and wide-angle shooting macro shots, like the four corners will be apparent perspective distortion. Note that when shooting, the photographer and the distance between models. But also to keep the camera level with the model into. Do not be made into a model of the small nose big nose.

4. Macro magnification due to the subject,HP Compaq Business Notebook 6715b laptop battery so a slight vibration when shooting will have a serious impact on the image, so in the absence of sufficient light, and finally use the tripod, or take your camera predict with confidence.

5. To obtain a good depth of field, but also pay attention to the distance between the subject and the background behind, and if too close to the background and the subject is no way to have good depth of field effects.

While the use of large aperture metering should also note that, as shown above,COMPAQ Presario CQ70 Battery although the depth of field effect is obvious, but the model’s face has appeared a bit overexposed.

In fact, application of the macro is nothing new in the portraits, many professional photographers do in the salon-type photos taken when using this method too. Macro portrait was not hard, as long as we practice more, I believe we can make good use of.

Today we talk about the theme of “indoor swimming beauty photography.” We’ve talked about the beach swimsuit beauty photography, but I do not think we will be at the beach all summer, after all we have to learn and work to do. So for them who love swimming GGMM, swimming pool must have is often the place to go. In fact, the pool can also be a good swimsuit photo shoot, well, without further ado, we cut to the chase.
The basic one shot beauty – high-angle or low angle
Most digital cameras will have a “portrait” mode, but the active use of this model seem to be very small. Because this model and use the AUTO file photos almost no difference. In fact,NIKON en-el12 battery SLR camera, portrait mode main function is to open the aperture to the maximum extent possible so that the background behind the virtual character of (its purpose is to separate the characters from the background of prominent figures of the very effective). But compact digital cameras is basically how to adjust the aperture will not make too much blur the background (this is because the CCD compact size is too small DC caused the specific not be discussed here), so the portrait is not much significance.
Even so, we recommend to make use of the camera to take pictures Wang Yuanduan character features, so how many can play the role of some of the virtual background. But shooting people, the most important is not what the scene mode using the camera, but there is a real key factors at work.
People generally take pictures when we will without hesitation put the camera flat and the height of the eye. Especially male friends in the picture when the MM are basically men is relatively high, so the camera is easy to form when the angle from the top down. This perspective causes for the MM head of the photo and the body small (it looks to be shorter-than-life) of the results. Unless there are special purpose, or be made into such general MM definitely unhappy.
The correct way is, the camera should be slightly bent over time, so that when the camera is in your posture, the height of the upper and lower chest, so to be able to shoot ratio of the average, and impressive photos. While bent over to take pictures some trouble, but shorter than they shoot people who are very valuable. General magazines or on television we often see, the photographer when shooting models will bend over the back of the scene and Kazakhstan, is the reason.Dell Vostro 1310 Replacement battery
And in turn, shot up from below it, will make people’s head is relatively small, body looks high. But still have to pay attention to the performance of face-based. The use of extreme perspective of the following will be taken if the more interesting results.
The second took the basic beauty – wide-angle end and Wang Yuanduan
Another more important point is to use the wide side or Wang Yuanduan? To clear the difference between the wide-angle and telephoto shown, we used a relatively strong wide-angle Canon “Powershot S60″ to shoot. When shooting wide-angle side with DC characters will be relatively close distance, but when you take pictures using the Wang Yuanduan distance farther away.
Difference is very obvious that the photo shoot wide-angle end, a sense of distance and dimension are exaggerated, and the use Wang Yuanduan photo shoot, then beneath a sense of distance and dimension.CANON NB-4L camera battery

Wang Yuanduan photographs can try to shoot only to see the distal half-length photo, looks better than photos taken with wide-angle end of the legs look short, but also lost a sense of distance, will people feel dull. If you are using to shoot this POSE Wang Yuanduan words (such as 外拍 activities pull, auto shows, where like friends), you can try to shoot into the screen without legs to improve the sense of distance and intimacy.
The third basic beauty shot – looks brighter as far as possible
Summer,HP Compaq Business Notebook nx6125 laptop battery swimwear, of course, for the kind of cheerful, bright atmosphere. Especially in the summer the beach or pool, due to more intense sunlight, so the sky or the sea water swimming pool, much brighter than the figures should be. At this time if it is for DC to control their exposure metering, would beauty looks pretty dark.
Then there are two ways to avoid this situation, one of which is exposure compensation. When using the camera automatic transmission, prone to darker character’s face was cover the situation in the shadow of the hair. This is because the brighter the background, so that the camera’s metering system to produce the illusion caused.
However,HP Compaq Business Notebook 6515b laptop battery exposure compensation when using the entire screen would become bright, photos, the atmosphere is completely different. Especially in the summer, the girl in the photo not care if you have been exposed to the sky, no details, as long as their own white enough. If the film feel somewhat dark beauty, you can increase the exposure compensation to fix one.
If you increase the exposure compensation is also dark, then we should use the second method is to use flash fill light. DC in the daytime use of compulsory flash function to fill light can be a. And can make eyes appear reflective white point (commonly known as the eyes light), very beautiful. If used properly,price of HP Pavilion dv6 battery can produce eye girl comic characters often appear in results.
But even so, it will all happen, for example, sunlight is too strong, even with the DC flash fill light effect is not large, or because the beauty is too far away from the camera, more than a flash in the effective coverage, etc., necessary changes different to different response, in short, to play back at any time through the LCD screen, just shoot down the photos to confirm.
