I did look into using post-processing using either PSP or Photoshop and found the problem that Laurent mentioned - ie. many of the interesting effects work OK up to around 2000 pixels but beyond that you can't up-scale the effect to say an 8000*6000 image (even if you do have a system that could manage it). Obviously the simple overall colour/brightness/contrast changes don't suffer from this problem and I'd hesitate to call using those post-processing at all as they work on a per-image rather than per-pixel basis. I'd suggest we petition the programmer/s (Frederik) to add image processing to the facilities in the fractal program on the same basis as the formulas ie. so people can write their own post-processing algorithms (I think I see a flying pig).
