With film, the camera is just a light tight box - the lens is king.
With digital, the lens is still very important, but no longer is the camera just a light tight box, the sensor counts too. My 5D2 sensor is light years ahead of my G1 sensor, which doesn't even compete with my 5D1 sensor. I need that GH3.
Nor does film or digital see what we see. It just doesn't. So treat it as data.
My favourite photography was b&w, I could spend 3 or 4 hrs in the darkroom trying to get one display print just so. Paper flashing, split filter printing, dodging and burning and using toners to get the right result. Expose and process for a flat boring neg, then work your magic in the darkroom.
Nor is it necessarily about what you saw, it's about how you felt, emotion, what you want others to see.
I stick to the old rule of never to add or take away anything that wasn't there when you took the snap (the odd bit of rubbish, or dust mark expected)
Final rule is, if somebody asks what darkroom or photoshop technique you used to get the result, well it makes you wonder........have I gone too far. Has too look natural. A bit like JJ Cale, lots of endless cleaver studio sound work to create the most wonderful natural sounding recordings.
Oh yeah I miss my old darkroom. Oh to shoot b&w film again.
