The idea for this thread comes from a conversation with CRogers on G+ and a script package from deviantart.
Somebody was asking when we finally gonna get non destructive adjustment layers as in Photoshop, and i remembered the deviantart script pack which is basically a memory aid for people who dont understand layermodes.
So here are some tricks how to imitate adjustment layers for non destructive image manipulation:
Saturation Adjustment:
create a new black layer on top of your (color) image and set the Mode to 'Color' (you will get a b/w image).
Inversion Adjustment:
create a new white layer on top of your image and set the Mode to 'Difference' (you will get a negative)
Sharpening Adjustment:
get RobA's HighPass Filter script (registry.gimp.org/node/7385), run it on your image and set the new layer to 'Grain Merge' or 'Hard Light' (this will sharpen your image)
Adjust Lights, Darks or Mids:
use this tutorial (clownfishcafe.blogspot.co.uk/2013/11/color-pop-on-midtone-grayscale.html) to manipulate specific value parts of an image with a layermask.
Any more non destructive tweaking tricks ??
