What is it?
Silicosaur PhotoFX is a collection of script-fu macros for GIMP (GNU Image Manipulation Program) to easily simulate development methods and film types used by photographers of pre-digital age.
You can transform your digital image into an old fashioned film positive with a single click. And - of course - all the scripts are licenced under GPL, which means, they are free.
Any comment about possible improvements will be appreciated.
PortraFX simulates Portra color film of Kodak used to make portraits by professional film photographers.
ProviaFX simulates Provia daylight balanced reversal film by FujiFilm for landscape photographers.
VelviaFX simulates Velvia which is a higher-saturation reversal film for landscapes also by Fujifilm.
CrossProcessingFX simulates Cross Processing (sometimes called x-pro) which is a development method processing photographic film in a chemical solution intended for a different type of film. If you want to know more about it, visit the wikipedia page of cross processing.
