Greenscreen Photography is a technology to change the background of the original image by replacing the existing with the new one. Greenscreen technology is also called as a Chroma Key effect; here, the photographer will replace the background image digitally. The process of image merging has been done through the editing software. In greenscreen technology, the background color can be either green or blue. Because of these two colors are the best contrast colors for human skin. Using greenscreen photography, you can create some special effects in your photos.
