“I’d be fascinated by what the grain did because it would make a kind of tapestry of all those little dots and everything would be translated into this medium of dots. Skin would be the same as water would be the same as sky and you were dealing mostly in dark and light, not so much flesh and blood.”
Even though Diane is referring here to dark room processing; I have found the same to be true in digital processing. If we replace the word 'grain' with 'noise' and 'dots' with 'pixels' the above quote can be applied to digital image processing as much as dark room processing - both equally as fascinating.
