 All the encoding and correction methods can be arbitrarily superimposed, without mutual knowledge of this fact among the different elements; if done incorrectly, these conversions can lead to highly distorted results, but if done correctly as dictated by standards and conventions will lead to a properly functioning system.In a typical system, for example from camera through JPEG file to display, the role of gamma correction will involve several cooperating parts.The camera encodes its rendered image into the JPEG file using one of the standard gamma values such as 2.2, for storage and transmission.
