Episode 073: Layers

This week Rolf tries to explain layers, the layers dialogue  and layer modes. The image on the left is a result of a little play with layers: a layer with a screen shot of GIMP was duplicated, set to “Grain Extract” mode, shifted two pixels to the left and top and than duplicated again. Looks nice – but why? 😉

Layers are an important tool in image manipulation. You can isolate different parts of an image with layer masks and so avoid negative consequences of your actions to other parts of the image. And you can play work with different layer modes to achieve effects from a little contrast manipulation to complex changes.
