Everyday the traffic is used for transmitting the low quality web camera video. But you may feel ashamed when you are told that the poor video can be modified. Now we talk about the lighting. Below we will talk about the five common problems of web video and the corresponding processing methods.
First, don't take the computer screen as the light source. I think you have the kind of experience. You may make or receiver such video. As far as I am concerned, it should be the worst case. But it's used by most of the web camera users.
What's the color of the desktop? Blue? The solution is to turn on the reading lamp. You may use an ajustable desk lamp. You will find that the front bright light will low the overall exposure rate of camera and make the darker background. But the bright hard light of the lamp seems not to be perfect.
Second, soften the light. You can use the printing paper to scatter the light. A simple piece of office product can give a soft light source. The hard light will be softer as you stick the paper arount the front opening. In addition, the printing paper lowers the brightness of the lamp. Then the background becomes brighter. If there is a wall, you can turn over the lamp. The light will be reflected by the wall. A larger and softer light source is created successfully. You can turn off the background light because the dim front light makes it seems to be too bright.
Third, eliminate the reflection of computer in the eye. The adding light solves the glare problem produced by computer monitor to some extent. You can turn down the brightness and contrast of the monitor until it's comfortable to look. Thus, with the lamp as the front light source, the reflection will be eliminated. If you don't wear glasses, it's not tha important. But if not, it's better to let your friends see your eyes clearly.
Next, satisfy the video needs of the camera. Will you get red face when you use web camera? Actually, there is a problem with the camera automatic exposure and white balance. If there is no white color in the front view, there would not be good white balance. You can wear a white T-shirt. Then you will get bright color and full exposure when you shoot with the camera.
The camera will try to make the entered object become whiter no matter whether the object itself is white or not. So if there is whte objects in front view, the exposure and color problem will be solved. Then there will not be color changes during the video chatting.
Finally, clear the background. It's the visual clearing instead of the actual clearing. If you often use the web camera, you can buy a folding background panel. It will bring many benefits to you. If you are a photo grapher, it can also be used as a portable studio background.
