All compositing involves replacing selected parts of an image with other materials, usually, but not always, from another image. In the digital compositing method, software commands specify a narrowly defined color as part of the image to be replaced. The software (eg, Natron) then replaces each pixel in the specified color range with a pixel from another image aligned to appear as part of the original.
- Multiple Exposure
- Blue or Green Screen
- Physical Compositing
- Front or Rear Projection
Also 3D compositing can be extremely challenging, but it can also be very creative. Unfortunately, one of the difficult parts of compositing is creating a format that can be used in a variety of editing environments.
The purpose of compositing is to visually depict things other than the reality of an image.
