The set includes 4 actions that are used to fix the purple color shift. A small version of CornerFix but faster processing by just one click. Some mirrorless cameras like Sony Nex-7, and the hottest Sony A7, A7R produce color shift at the corners with RF wide angle lenses. This action set is created to heal this issue in some level. Depending on the color shift level, all layers can be modifiable and customizable of your taste.
