Retinex is a quite specific operation, that does local contrast enhancement and whitebalancing on an image. In the GEGL tool you should find other ops that have somewhat similar intentions: fattal02, mantiuk06, reinhard05 and stress - perhaps one of them does a better job in your opinion? (some of these are rather expensive operations to compute) Like with any other op - if you want to affect only portions of an image; shadows only or similar; creating a mask to adjust which pixels are affected how much is business as usual - doing this could perhaps be made easier overall in GIMP; but integrating it in the operations themselves could almost be likened to adding a sharpening step or similar to brightness contrast/curves/blur and similar. /Ø -- «The future is already here.
