Green Screen refers to an editing technique in which two images are merged together to create single image. This is one of the advanced techniques used to situate people in the places beyond imagination. The technology delivers mesmerizing effects that you watch in commercial advertisement, portrait photography, film, television stations and much more.

There are few points that a photographer should consider before shooting for a film or a photograph with green screen technology. This technology is also called chroma key editing. A photographer should light the foreground subject properly. Proper lighting of the subject prevents shadows or patches falling on the subject. As a background, you can use green or blue color while shooting. It is not easy to determine which color one should deploy as the background. One point that a photographer should consider is that his subject should wear as little as possible the color used in the background. For instance, if the subject is wearing green color shirt a photographer should use blue color as the background. One can use green shade only when the subject is not wearing anything green. You use a green shade in a case when you want to show a green hilly area as your background. A photographer uses these two colors in the technology because image censors in the camera are sensitive to these colors. A professional photographer should get the wall painted blue or green. He can also mount a green or blue color cloth on the wall. However, the cloth should not contain any crease. A creased cloth in the background can cause unnecessary shadows when the final photograph or film produced. After photographing the subject, you can use the editing technique to replace the background with your desired photograph.

The technology has become so advanced that to picture a subject in the desired location has now become feasible at any place. There are many chromakey editing software available that are useful for novice as well as professional photographers. It can be used for photo shoots, commercial advertisements and for many more purposes. One can even deploy the technique at home as well.
