Video Editing: A Step Ahead With Green Screen Technology
Video Editing has never become as easy as ever with green screen technique. The technique is also called chroma key editing. It is editing technique in which two images are fused together to create a single and finished image. Photographers use this technique extensively in film and television to create a wide range of special effects.
Procedure of Green Screen Technology:
"Chroma" means color in video jargon and chromakeying works by shooting a subject against a background of a very simple and uniform color. A photographer uses blue or green color screens because they are as far away from human skin tones as it is possible to get. Additionally it is easy to use these two colors, as they are sensitive to the image sensors in the camera. The subject should not wear blue or green color clothes that can be same as that of the background screen. It effects the editing of the photograph or video. The background screen should be uniformly lit and even the foreground subject. This is to prevent any kind of shadows on the subject or on the background screen. Keep subject and background as far apart as possible. After the shooting, editing software replaces the background color by another shot chosen by the photographer. The most common example is that of a map behind the weatherman in the news stations. The person is actually standing in front of a green or blue color screen that replaced in the control room with a background image of a map.
Uses of the Green Screen Technology:
Video editing with chroma key technology is a user-friendly procedure to transform your videos and images and personalize them the way you desire. Mainly professionals deploy this method and they use for photo shoots for magazines, advertisements, newspapers and for the Internet. In Portrait Photography, a photographer uses such kind of technique. One uses the method commonly in the television or news stations. A video editor uses the procedure often in films that saves time and money in shooting. If you see your favorite actor climbing the wall or getting invisible, it is the result of this technology. The people who have photography as their hobby can also use it. One can use the technique at home as well. You need to mount a solid blue or green colored sheet on the wall. Take the pictures that you need to replace and after shooting the foreground subject use an advanced photo program to edit. This will eliminate the background of the picture and replace it with another. Teachers can also use the technology by placing the image of a student in the area of the topic that they are learning. It is great fun for a person to use this advanced technology with expediency.

for chromakey backgrounds when shooting video which colour is better, blue or green screen?
what colour is better for a new chromakey tv/special effects studio blue or green?
For the most part, the color doesn't matter. As long as the background is evenly lit and no one is wearing colors similar to the background, either will work perfectly fine. Green is usually used now since most people are going digital, and the digital sensor is more sensitive to green than the other colors (green makes up 50% of the digital sensor on single CCD cameras, not the case in 3 CCD cameras though)

Green Screen Wizard - Neat and Easy Photo Editing
You can add a new dynamic to your photo hobby or business with a technique that will give you the edge on competition and save you time in the process. You are most likely familiar with green screen or chroma key techniques. They have been used extensively in Television, and in particular on weather broadcasts. The weather forecaster stands in front of a solid colored surface while delivering the weather news. It looks as if there is a weather map right behind her, but in reality, the weather map is on a computer somewhere else.
This technique has been copied by photo editors for years. The editor will use photo editing tools to extract the model from the background and place her into a scene in a different photo. If done correctly, it appears that the model was on location for the photo shoot. It is a really cool effect, and volumes have been written about how to accomplish it.
Well, now you have the process available to you with just a few clicks of your mouse. You will need to take a photo of your subject against a solid green or blue background. You are not limited to people, either. Think about the product shots you could create. The sky is the limit.
This process could also be a whole new creative niche in your photography business or hobby. You can photograph kids, adults, pets, you name it. The original photos are again taken against the solid background, then they are processed with the Green Screen Wizard software, which comes in a stand-alone version as well as a Photoshop plugin. Another creative way to use your new software is to put the subjects into a magazine cover.
Of course, all of these things have been done in the past, but the dedicated software makes it so much easier. And here is another added bonus - there is almost zero learning curve. Anyone who has done any photo editing at all can do this. It really is a simple click after the photos are arranged in layers.
You can try Green Screen Wizard for free. Check it out, it is definitely worth a look. Click Here to see the graphics.
