A Review on Green Screen Technology

Green screen technology is widely used in television studios or film making sets. It is an advanced form of technique in which the background of the subject is replaced by any other image. It is used by amateur as well as professional photographers for shoots in magazines, films, newspapers and on the Internet. This kind of photography can also be used at home. You need a high quality camera, proper lighting as well as a green background. With all these equipments, you can make your boundless imagination to turn into a reality.

Uses:

There are many uses of the green screen technology. It is used by the photographers in film making. You can make your actor act out a scene against the green screen background. Then you can replace the background screen by any other footage. In this way, a photographer can make his actor climb the mountains, fly high in the skies or falling from a tall building and meeting a tragic end. Anchors are also placed in front of a green color background screen and read out weather forecasts or other news stories to the audience. You can use this form of picture making in advertisement field for advertising a product with your subject. One can also create portrait photography with the advanced technology.

Equipments used in this technology:


A photographer should be able to select a high quality camera. There are several types of camera such as Point and Shoot camera, Single Lens Reflex camera, full digital SLR camera, etc. Point and Shoot camera has built in flash and some cannot set white balance. The built in flash might cast harsh shadows on the subject. You cannot depend on the light of the flash in the camera.

Full digital SLR camera is the best as it has interchangeable lens. You should select a green color muslin, Chroma Key paint or woven polyester. Do not use plastic sheets as they reflect light. Studio lights are the best as they have diffusers attached. These diffusers eliminate unnecessary amount of light and gives soft appearance of the subject in the video or picture. All these are important equipments used in the technology.
