Here are some more information for Key Editing:

A green screen process is an advanced form of photography that is used for replacing background image of the subject by any other selected image. This kind of picture making is done by the photographers with the help of advanced video editing tools. You can customize the videos or images as per the requirement. This kind of process enables a user to transform the subject in a world of imagination and creativity that has got no bounds and limits.

Pre-requisites of green screen editing:

For performing green screen editing, you need to place a subject against a green color background. A person can also select a blue shaded background as these two shades are the farthest from the human skin tone. Above all, these two shades are sensitive to the camera sensors. The cloth that you use as a background should be without any creases or folds. If the cloth is ironed before being used, it does not create any problem in masking process. If a person performs the masking process by placing a subject against a folded or pleated green or blue shaded background, then the background image does not get clearly replaced by any other graphics. Proper lighting system is another factor that counts when a video or an image is shot. Good lighting system eliminates all dark shadows or dark areas from the background or the subject. You can make use of "three point lighting system" for effective and impressive output of final videos and images. The "three point lighting system" includes a key light which means that lightens up the entire background area and even the subject. Then you have back light that is responsible for removing the shadows at the back of the person being shot. Lastly, fill light is the one that removes all sorts of shadows or dark areas from the face or clothes of the subject. Use flood lights and amber gels for soft and colorful effects. Hence, you can make your editing for green screen picture making beautiful and impressive.

They use this technique to create wonders in the videos or pictures and make them emphatic and memorable. It is an easy to use method which can also be used by the photography lovers. It enables you capturing beautiful moments of life and you can make them impressive and exotic even more by using advanced technique.

The digital Chroma Key effects can be created in the studio with proper lighting. The photographer should first capture and gather the pictures to use at the background of the subject. Next comes displaying the background color behind the subject. You can use either green or blue color screen at the background. These colors are majorly used as they are sensitive to the image sensors in the camera. However, the cloth or paper used as the background screen should not be creased or folded. This might not mask the background screen properly through the digital equipment. The color of the screen should not match with the cloth of the subject. The digital camera used should be of high quality and authentic. The camera can clearly focus on the subject and show the colors of the picture clearly. Another essential thing is to use clamp lights for proper lighting. If the lighting is properly used it can leave a good visual effect. The subject should be well lit along with the background. You can also use reflectors to create visual effect while photographing the subject. A person can use amber gels for the visual impact on the subject. These amber gels are colorful thin plastic sheets used for reflecting colorful light on the face or hair of the subject. You can use butterfly sheets for leaving a soft effect on the face of the subject. A photographer can create numerous effects with all these equipments.

You can create transition and overlay effects by superimposing the selected image on the subject. One can even clone the subject by placing two pictures of the subject against each other. You can also make the subject fly high in the air or climb huge mountain using this technique. With this chroma key editing technique you can create countless pictures easily.
