I don't care much for post-processing, whether in a computer or a darkroom, so E-6 and in-camera adjustments have always been what gives me full control over my images. That plus the impact of a projected slide have kept me shooting it for my serious stuff, although I love the newer C-41s for family shots and messing around (it helps to have a local pro lab that makes great prints). I also sell some work and more publishers still prefer slides over color prints.
