Episode 073: Layers

Download the Video!
Download the companion file! (…if there is one…. 😉 )

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.

We need Tables of Content for the back episodes. You can help by joining this thread in the Forum.

  1. Harsh enforcer 😀 Sounds dangerous… Don’t be frightened by these words – a useful post at the wrong place is better than no post at all 😉
    Thanks to Rolf for showing some of my techniques in the past videos to share them with all the MTG viewers – not only with the forum readers.

  2. “Tables of Content”

    As a native English speaker accustomed to seeing
    nonsense like “Table of Content’s” from fellow
    English people, let alone people for whom English
    is a second language, I salute you.

    PS the screencasts are excellent too 🙂

  3. Thanks Rolf another great episode.

    AmZer, you might have a look at episodes 32,33 and 34 which have some detail about channels.
