Summary
[edit]
| Description | The following is an example of a scenario where posterization may occur, and relates to the image above. A photo saved in JPEG has 256 variations of luminosity in Red, Green and Blue (RGB) in which to derive its colours. This is approximately 16.7 million colours (256*256*256). However, if you were to take this image and save it as a GIF format image, which has a total of only 256 variations of RGB in which to work with, then the subtle transitions in colour and luminosity that your original photo contained may end up in very obvious and aesthetically unpleasing 'jumps' from one shade to another. This is posterization. |
