1, long focal length

What is the best portrait lens shot? A medium telephoto zoom or fixed focus lens can handle. If you use the 35 mm film shot, this means that you should use 85-135 mm focal length lens. Due to a shorter focal length (50 mm or less) often shoot portraits of people facial features exaggerated, and sometimes makes the nose appear large than the actual, you will make friends, thus disappointing.

Often referred to as portrait lens with the 85-135 mm longer lens, the perspective is somewhat compressed, so that facial features would show the correct ratio. To use more than the 200 mm focal length lens, then make the face look peaceful.

Telescope with a moderate head portrait results were better. 35 mm wide-angle lens with a close shot of the face too ugly. But with 105 mm focal length portrait lens compresses the perspective taken and facial features,HP Compaq NX7400 battery the performance of the subject who was naturally pleasing to the eye.

2, close to the point

Portrait photographers have no experience of failure is another reason they did not shoot as close as possible. If you shoot the characters on the screen is too small, so that their faces and expressions can not be the center of the picture at a glance the performance, then the results have sent. The solution is then close to some shooting. You went up to close to being photographed, or shooting with longer focal length lens. Nearly produced the United States. The famous war photographer Robert Capa said that if your picture looks good enough, it is because you are not relying on the past. Portrait photo of it which is of course right. The above photo was taken at a distance of 15 feet, both not really portraits, is not really city photos. The following figure, as close to being photographed, the effect is the portrait of no one doubt it, but also a successful portrait. By the way, the figure still another common problem, that person’s head at the center of the frame. In the portrait composition, we should try to keep the relevant departments in the upper half of the screen.

3, the use of large aperture

In the living room you built a small studio, you can certainly shoot for the children than the supermarket share in the establishment of a better self-photography’s photo. One thing to note is that you should avoid using a small aperture f/11 to f/22. With a small aperture for shooting in bright light scenery is good, but will be a problem for shooting portraits. Small aperture makes the background look very clear, it will divert the attention of being photographed. f/1.8 to f / 4 large aperture bokeh can make in out of focus, and let the mothers and children to become the only people concerned about the mother and son photo of the target.battery for Toshiba PA3420U-1BRS battery
However, large aperture has the potential to shallow depth of field, if the camera’s eye than the other farther away from the camera, then the distance of the eye may be in focus away. The remedy is to discard the background when shooting so that you can use a smaller aperture of a block, or adjust the position was reported on the head, eyes and cameras to the same distance.
      You have to show is that you be proactive rather than a background. In the above painting portraits taken with the f/16 on the background is quite clear. People will try to distinguish between what is or where it is. In the bottom piece of a more powerful shot with the f/2.8 portrait does not exist on the background of distracting issues. People’s attention will focus on the desired place in the photographer: those who were taken. However, virtual background is not always necessary. You may wish to try making an environmental portrait, for which you need to keep around the clear background and detail through the environmental features to be introduced being photographed.

4, try vertical picture composition

Portrait photography is one common mistake made by novice is to portrait made into a horizontal screen. The composition across the screen is good for the group portrait, but when you shoot a single person to take the camera to the vertical screen position. Jian more suitable for single-frame shooting portraits, because the frame itself or with the head vertical head and upper body corresponds to a rectangular shape. Vertical structure is also suitable for dry couples photo shoot, especially when they embrace the time. Intimate romantic couple make vividly demonstrated.

Using cross-frame to the attention of some problems.Compaq tc4400 battery For example, the banner above portrait is good, but please take note of the way from the chest cut so that the screen seems stiff and unnatural. Of people to choose the most natural cut the narrowest parts of the body, such as the neck and waist. The figure on the subject’s vertical screen viewing the site using this cut to achieve a relatively balanced and satisfactory composition.

5, to avoid the glaring light

Portraits from scratch is to use the most taboo down on top of direct sunlight. It will orbit, around the nose and chin caused by shadows. To avoid this destructive effect of light, professional portrait photographer like the shade of the open space use, such as a sunny day under the big tree, surrounded by a large number of reflected light can be on local shadow fill light, in the face of the formation of character is not smooth shadow lighting.

If you have to capture portraits at noon, you can easily create their own shadow of an open back condition that allows those to be taken back to the sun, technically called backlighting. This is your camera light meter will form a challenge, here are ways to solve this problem. To improve the above results taken with the direct sunlight, can be a translucent white umbrella blocking the sun at noon. Another approach is to use the lighting to solve the problem, but the light around the subject who would interfere with your exposure meter caused by lack of character. To avoid this situation, you should be photographed near the facial measurements taken directly from the exposure readings. Or if you can persuade the camera a little meter, then use it to take the subject by measuring the reflected light of the face better.

6, choose a simple dress

Dizzying color clothing will only shift the audience’s attention on the subject. To use the simple design and quiet colors. If you plan to shoot some casual portraits, you can hand a simple T-shirt standing. For Otsuchi camera, put a piece of red or blue satin material resting on her upper body around with other external fixation, to replace the strapless evening dress or open collar. If you encounter when shooting was photographed wearing a timely fashion is not Taiwan, will have to find ways to change this. Composition on the screen can be handled more compact and thus avoid the flashy pieces that shirt, or light the area at the time of the shirt to stay in the shadows,Price of Toshiba PA3420U-1BRS battery
and to face relatively more brighter.

People dress to keep it simple. Fancy dress make people put those features on the subject of attention to people who (above). In color, keep it simple dress is usually effective. Bright primary colors can add angry portrait (below). But should be selected to be photographed with the true nature of good fit of the clothing. If possible, choose to be photographed clothing colors, this effect will be the best. Almost all people know what color will make them look best. If he or she dressed in clothing that matches the color, then the subject’s sky blue or Caise eyes will be more apparent. (Red, green, blue complementary color is yellow, magenta, blue)

It is often said, the challenges facing artists is how to draw a blank piece of paper, plus there are some things to make it art; and the challenges facing the photographer is very different, they want cluttered environment, more than the use of composition techniques, independent of the scene to remove them, so that the screen seems to have art.

In other words, painting from a blank screen, and then decided to add something within the frame, to express their own ideas. Photographer (unless it is a static display) are concerned, is how to arrange the elements within the existing features in order to express their own ideas. To shoot a good photographer works on the composition must be the pursuit of harmony.

Over the years, summarized some people get a good Aspire 5570 battery photographic composition should follow the basic rules, these rules in a number of photography books and articles, has presented itself a lot. Some foreign artists have often warned people photography, photography composition rules should not be too rigidly stick to, because it freed people’s creativity, it is important to understand the “spirit” and “role.” In fact, many of their masterpieces are based on these principles is not to create the. However, for beginners, there are guiding role of the composition guidelines, easy entry; for most photographers, the composition usually remember some of the essentials, before shooting can vividly imagine what will shoot photos look, for the successful creation is also some excellent photographs great help.

American photographer L. Little Jacob Heath said: “The NP-FH50 Battery composition is the photographer’s mind from the start of the eyes. Composition of the process is also known as the ‘expected’, that is, an object without shooting or being shot before the time, you can in my mind to form an image or impression. through regular analysis of their composition and work of others, this will make their ability to foresee more skill, become a kind of instinct. ”

Haas Austrian photographer Yiniesite this view is shared, for the composition, he had reached the hands of non-sword, sword in the heart of the A1181 Battery state, he believes that “the composition is balanced, balanced treatment of each person are different. “Just as the highest realm of martial arts, the name has no moves, just by his own skill to resolve. Composition on the camera’s position, he said: “The more you can forget your equipment, * the more you can focus on subject matter and composition, then the camera is just a continuation of your eyes, no other significance.”

Little Jacobs also said: “The composition of the most fundamental factor is the line, form, texture and the space between these factors. Of course the color is also a non-negligible factor. Converging lines of perspective is generally that relationship, but not all photos have to show the depth of perspective not. many works of art are planar patterns. in the viewfinder of a scene or character portraits, are based on personal feelings photographer arranged. So, how composition, and how to select the main, light, color, can also become a photographer based on unique personal style.

“In most cases, each piece has a HP Compaq Business Notebook 6910p Battery photo or a group plays a leading role in the shape or form, and color photos, size, location and other shapes, are the dominant factor for the service,” “composition of contrast, refers to the large and small, light and dark, near and far, active and passive, smooth and rough, rich ruby color and dim, and so the contrast. to make more use of these conflicting factors, the main gate through which affect the entire composition. For example, the proper use of comparative law, photographs will be very powerful charm. ”

Some people may be gifted to the composition. However, according to American photographer Willy Quaker views, almost all of them are able to apply some basic rules, to a considerable level of photographic Sony laptop battery composition skills. To this end, he made some simple methods. He believes that, based on these methods, anyone can learn to shoot better in a short time the photos.

Village Quick pointed out that the photographer is the most likely mistakes I wish point shot made too high, and the subject is too far away, causing the screen to various forms and purposes unrelated shooting things. He said: “Remember, the artist is drawing something into the screen, and the photographer is something removed from the screen.” He said: “The photo should be only one center of interest, whether on the screen with the HP Compaq Business Notebook 6710s Battery thing can not be . If you have an object is suspected to contribute to the screen, you should abandon it as much as possible. ”

Photographic composition rules, people are most familiar is probably the so-called “rule of thirds”, and soon were divided into three vertical and horizontal screen, so that the screen is divided into nine equal squares, there are four cross four separate line of point. Usually the photographer to select four points in this one the best location as the center of interest (see Figure 3-1). Those crossing the screen right, generally is considered the strongest. But Quick said: “This is not to say that the center of interest have to be accurately placed in the intersection is not. That is why, in fact, the center of interest is found in the vicinity of the intersection.” Quick said: “Each should be a picture maintain a certain balance. This means that the main subject of the arrangement, can not make art, face appears on one side to the dumping of large EliteBook 8530P Battery components. But balance does not mean that the two the same size and placed in the same symmetrical shape of things position. This relationship, as long as you look at the seesaw kids to know. seesaw both sides of the child, must sit in a smaller farther away from the central place, and a large children must sit close to the central place. ”

Quick said: “The arrangements for the prominent lines, point to the center of interest, take a pleasing photograph is another factor. These lines are called the leading line, effective use of leading lines, you can create a stunning photo. The dominant line arranged in diagonal, will have a strong dynamic. “lines often provide a frame in the photo. This can be carried out by selecting the point of view, such as tree branches framed by your subject on the screen. Usually at this time using a small aperture to make the whole clear photos. This also has the potential to highlight the Apple laptop battery border too, but properly arranged, will be good photos.

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.

3, for macro shooting is pay more attention to composition, use the golden ratio of line composition. Shooting Mode Olympus E-420 not only provides macro shooting, as well as the natural function of macro photography, macro mode allows the two segments are a good, targeted, users can choose according to their needs .

How to use the Olympus E-420 shooting night

1, the shooting was set up three-legged Jiala night, of course, or a long period of extended exposure will shake caused by hand-held images with fuzzy, but need to purchase a tripod is more stable, after all, is the Olympus E-420 SLR models, the component does not small, if it is supported by a small DC tripod also be affected by vibration.

2, the shooting will dial to M file settings,price of Dell Inspiron 9400 battery aperture can be scaled to a small aperture, may also wish to F22, while the 10S is recommended around the shutter exposure, and may, depending on the circumstances may be, under normal circumstances, will capture as proof-like lighting effects.

3, As for the contrast and saturation adjustment mentioned above can be appropriately adjusted.

4, ISO may wish to use the minimum value, due to inadequate lighting at night, under the high ISO will produce more noise, the overall picture effect will be added, so ISO100 to be more appropriate.

5, the user is a novice, then select the scene mode can also be night shooting, the pattern is more relaxed, the same night would be a good performance results.

Expert Advisory Station
Anhui, Hu Hongxi: Recently, an Internet cafe in Hefei occur bombings, the associate had previously seen some of the reports of the cafes repeated security threats, as the owners of Internet cafes, I was very scared. May I ask what measures need to be taken, in order to reduce the risk?
A: The security for any Internet cafes are a top priority. Internet cafe owners and managers must have a high degree of safety awareness and establish a sound safety management system, in order to ensure the safety of the lives and property of the Internet staff. An important position in the Internet cafe, we can install monitoring equipment, camera video monitor targets, so you can record the Internet cafes and from every move. You can also install a voice alarm system,Compaq NX9010 battery in order to deter criminals. In addition, in the striking position of the cafes (such as walls, columns and other places), paste some banners, posters, a reminder to all cafes customer in order to prevent the crime occurred. Internet cafe management personnel in the face of some illegal behavior, but also in time to stop, to avoid worsening of the situation, thereby protecting the legitimate rights and interests of the cafes own.
In addition to the above measures, as the owners of Internet cafes also understand the relevant national norms cafe operators behavior and safety management regulations.

Ask for unexpected blackouts how to deal with it?
A: Under normal circumstances, when the blackout phenomenon occurs when night and day, night, the probability of an accident is much greater than during the day. Therefore, in the event of a blackout phenomenon, we can advance to do the following things: 1. Internet cafes as a place to pay Internet Services customer, all customers access to the Internet time and cost can not be calculated as a safeguard against power outages, we can provide a good performance UPS power supply for computer billing. Of course, under conditions permitting,Toshiba PA3465U-1BRS replacement battery we can for the client in the Internet cafes UPS uninterruptible power supply service.
Two. Prepared in advance, emergency lights and other equipment, can also buy some flashlights, candles, to prepare for contingencies. 3. To allow a safe passage in the cafe, who are able to organize safe evacuation of Internet cafes exercises. So that when the blackout occurred, safe and orderly out of Internet cafes, to avoid confusion to cause the accident.

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: The phone’s screen color to 65,000 colors from the original monochrome, 4096 color, and then to 26 million colors, gradually from 2007, the mainstream mobile phone products with 16.7 million colors from screen, reflecting the rapid pace of development in digital products. However, the actual use of the feelings, 16.7 million color screen in color
The color performance (especially in the wide color gamut, color transition) compared with 260 000 colors enhance, but the difference is far from 65,000 colors and 260 000 colors so obvious gap. Therefore, for a modest budget, the consumer can ignore the difference of 16.7 million colors with 260 000 colors, to focus on other
Functional aspects. In addition, in the pursuit of the color of the screen at the same time, you also need to pay attention to the screen size and resolution. In addition, we buy mobile phone products,Compaq TC4200 battery there is an invisible indicators Do not forget, that is, the performance of the phone screen in the sunlight.
(2) Some people say that many of the MP4 is a pseudo widescreen products, then how to identify true widescreen and pseudo-widescreen, is not it the resolution?
A: The true widescreen and pseudo-widescreen identification method is very simple, is to look at the product screen resolution corresponding aspect ratio. If a so-called wide-screen resolution of 320 × 240 (ie, show a ratio of 3:2), that it uses the screen is the pseudo-widescreen; and 400 × 240
(WQVGA 16:9) screen is a true widescreen. In the purchase of digital products should carefully read the parameter list of the product, do not alone advertising agencies to buy products. Pseudo widescreen MP4 players will play the movie screen stretching, lead character becomes short and stout, the actual play
The effect of seriously widescreen MP4 poor.
What digital video camera connected to the computer interface is 1394 or USB port?
A: The digital camera and connected to the computer interface to existing 1394 interface USB interface, A / V interface. 1394 interface can be smoothly completed the acquisition of computer video.Toshiba PA3479U-1BRS battery replacement USB interface (USB2.0) video bandwidth is restricted, often can not be effectively collected, it is only appropriate
For still images (digital photos) to transfer to the computer. A / V interface used to connect to a TV, playback of DV.
Text pictures to use digital camera, and then use OCR text recognition software to identify, suggesting that the non-binary images can not be open,HP Mini 5103 Battery and ask how to deal with?
A: Typically, the OCR software can only recognize text in black and white picture, you use a digital camera image format is RGB or Grayscale format, OCR does not recognize. The solution is to make use of Photoshop and other image processing tools to the digital camera photos converted to black and white images
Format, and then use OCR to recognize that it should be.
I have a camera, every time you open in the first few seconds of their video screen color is not always normal, will gradually recover after a few seconds, is this why?
A: This phenomenon is normal, do not worry. The reason for this problem is the camera needs at startup after a period of warm-up time to work properly, the length of the warm-up time is to change with the sensitivity of the camera. Camera with automatic control functions, in the warm-up finished the image since
Automatically adjusted to the normal display.

Failure does not only affect the workstation card itself, but also often affects the normal operation of the entire network must be caused by network administrators attention. In Ethernet, the network card for connection and control of media access media access, Ethernet uses Carrier Sense Multiple Access / Collision Detection (CSMA / CD) is to be achieved in the card.

Meanwhile, the NIC is also responsible for the formation of the upper layer protocol data unit protocol (PDU) composed of Ethernet data frames sent to the network,price of ACER Aspire 3680 battery and is responsible for receiving and processing network, the Ethernet frames coming.

First, the card works

Send data, listen for the media card if the first carrier (the carrier by the voltage directive), if so, then that information is being transmitted to other sites, continue to listen media. Once the communication medium in a certain period of time (called the frame gap IFG = 9.6 microseconds) is quiet, that is not occupied by other sites, then send the data to begin the frame, while continuing to listen for communication media, to detect the conflict. During the transmission of data.

If a conflict is detected, immediately stop the meeting to send to the media to send a “block” signal to the other site has a conflict, thus discarding those who may have been damaged in the received frame data, and wait a random time (CSMA / CD algorithm to determine wait time is the binary exponential backoff algorithm). Waiting for a random time,Sony PCGA-BP2V battery then a new transmission. If, after re-transmission times (greater than 16) are still in conflict to give up the transmission.

Received, the NIC visit each frame transmitted on the media, if its length is less than 64 bytes, is considered to be fragments of the conflict. If the received frame is not a conflict of debris and the destination address is local address, then check the integrity of the frame, if the frame length is greater than 1518 bytes (known as jumbo frames, may be caused by the wrong LAN driver or due to interference) or failed CRC check, the distortion that occurred in the frame. By checking the frame is considered to be effective, it receives to carry out a card will be processed locally. Computer Basics

Second, the factors that affect the network card work

LAN card depends on its ability to work connected to the switching equipment and network card set produced by the interference of the working environment. Such as signal interference, ground interference,Dell LATITUDE D500 Battery power supply interference, radiated interference can have a significant impact on the performance of the card, some interference may also be a direct result of card damage. Computer

PC-card power failure led to often not working properly. Power failure may have fled to the discharge card jamming signal output port, before entering the network will take up a lot of network bandwidth, undermining the normal data packets of other stations to form a frame check a large number of FCS error packets, cause a lot of weight made frames and invalid frames, each workstation with its proportion of the increase of the actual flow, seriously interfere with the operation of the whole network system.

Impact of card grounding interference often work in bad ground, no place to release static electricity due to the accumulation in the chassis, so that the card ground (the top iron through the network card is connected directly with the chassis) voltage is not normal, eventually leading to the work card is not normal, even when serious this breakdown control chip on the NIC card causing damage.

Is very vulnerable to interference,APPLE A1181 laptop battery and sometimes the network card and graphics card will be inserted too close to interfere. Interference is not serious, the card can barely work when the user data traffic is not often feel, but a large amount of data during the communication, under Windows98 will appear in the “network of insufficient resources” message, causing the machine crash phenomenon.

NIC settings will also directly affect the speed of the workstation. PC card work for full-duplex and half duplex, when the servers, switches, workstations, working conditions do not match, such as servers, workstations, network card is set to full duplex state, switches, hubs, and so work in half-duplex state, will have a large impact frame and frame number of FCS error checking, access speed will become very slow, from the server, copy a 20MB file may also need 5 to 10 minutes.

This mistake is often due to the negligence of the network maintenance personnel, most of the time they use the default settings, but does not verify the actual state.

Come on! Come on! With the Wiki
: Angel Tyrrell
Hey, guys, I am a wiki, a lot of Knowledge in the world organization, due to the formation from the majority of users, so my knowledge is the most complete, can be said, is the world’s most intelligent site . How I was formed? In fact, because first of all, it was suggested that the entry,Price of Toshiba PA3480U-1BRS battery and then was added to complete, and ultimately the formation of a wiki page. Want to find the knowledge of who you can look through my search box to find.
But you ask, so, if a lot of friends at the same time add or modify, that there will be conflict, How do I choose? Hey,Dell Vostro 1710 battery my parents – the majority of smart programmers have long thought about this problem, they gave me think of three measures: 1. To maintain such a conflict, without any replacement operation by the editors to decide; to retain the results of last modification, the original of all the changes lost; does not modify the original version remain unchanged.
These are in accordance with the modified date records to the database, so the wiki version control is very important, my father, mother Gene Good, decided I so smart.
Every day, very busy, because I have the talent of Web 2.0,battery for HP hp 8510p so every day there are tens of thousands of users access, I will balance the load, according to statistics, the maximum time will be processed per second 30000 users access to every second I have to deal with the 3G bit of traffic, so I have 350 servers brothers and sisters, through the LVS load balancing, and I still have a giant cow Lighttpd on “Brothers to the picture services, In addition,Thinkpad X41 Battery I also have a very powerful caching mechanism, and through the distribution of all continents of the DNS server for reverse proxy, which are busy every day, but very orderly.
