Editing Compositing (section)

== Basic procedure ==
All compositing involves the replacement of selected parts of an image with other material, usually, but not always, from another image. In the digital method of compositing, software commands designate a narrowly defined color as the part of an image to be replaced.  Then the software (e.g. [[Natron (software)|Natron]]) replaces every pixel within the designated color range with a pixel from another image, aligned to appear as part of the original. For example, one could record a television [[weather presenter]] positioned in front of a plain blue or green background, while compositing software replaces only the designated blue or green color with [[Surface weather analysis|weather maps]].
