Photography has certainly come a long way in terms of innovations and the introduction of newer technologies. However, technological innovation never ends. Artists, designers, and programming professionals come together to innovate and introduce technologies to further improve the work of a variety of imaging professionals. Photography is not just about taking excellent images and then publishing or printing them. Sometimes photography also involves an extensive usage of high end compositing skills which often end up being unnoticed by viewers or the end user. The green screen effect is one such technology which has been around for a while. It is both effective as well as economical.

The purpose of using a green screen effect is more or less to incorporate backgrounds that are unreal or something that cannot exist in the physical world. However, this technology can also be used to place subjects in ...
... front of backgrounds which they desire. People often desire to picture themselves in before monuments or places of repute, such as the Seven Wonders of the World. This is not possible at times due to poor financial conditions or the inability to get to these destinations for various unforeseeable reasons. Somehow, the green screen provides them this convenience at affordable prices and for good reason.

Applying the green screen effect is the result of a simple technology. The screen uses a shade of green which does not occur commonly in nature. This is a standard shade of green which is used only for this purpose. However, the shade can be changed to ensure it does not exist in any part of the subject. Also, another reason for the usage of green is due to its low sensitivity to light and other imaging issues. Once the picture is taken it will be processed further to incorporate a background as per the client’s desire. Most photo studios do provide this solution.

The cost of setting up a green screen effect can get a little expensive. Hence, it is economical to look for a studio that already has a set up and would let you use it for nominal charges. Taking the picture is never the hard part however; editing the image later is a work of skill. Generally, a photo editing software does provide features that will enable you to create such images by extracting the green background and placing the image of your choice in place of it. But it would be advisable to look into applications that specialize in editing a green screen photo rather than the ones that are just meant for image editing.

This has its own advantages. You can customize the image as per you wish and place your desired background with precision. Then you could use a dedicated image editing application to add more details and supply enough realism to your picture. This technology is also known as the Chroma key effect and it also use to create live action films that need to make use of heavy special effects and addition of surreal backgrounds.
