The basic system I've developed for my own use over the years, for both colour and black and white work. When I sit down to process images, this is usually where it begins.
Each set includes three distinct looks, available as both presets and profiles, plus one variation (profile only):
COLOUR TRIAD 01
FILM GREEN
PUSHED01
RUBICON
RUBICON02 (profile only)
MONO TRIAD 01
MANN01
MANN02 (profile only)
AVEDON01
BAS01
All presets and profiles can be used on JPEG or raw files.
