Graphics: Influence Histograms

Optimization Week Issue #25, May 17, 2004

Histograms have a way of repeating themselves. You can avoid the banding blues by influencing your histograms to weight color palettes towards abrupt transition zones in your images. By using strategically placed selections you can tweak your histogram, and the resulting palette towards areas likely to create banding.
