Hi. I'm just about to start developing my own black and white, I've done it before at school but never on my own, and our teacher was somewhat wasteful. I can't afford to be wasteful. My question goes out to people like torus34 and stingray and others who know a lot about doing black and white.( hi will, until now i've just been getting stingray to do my film for me ). So i have some DD-X, and some delta 400. and some standard fixer. now i've read several thingos on how to dilute, and many give different ratios etc. 1:3, 1:1 etc. now, how will different dilutions effect develooping time, reusability of developing dilution, consistency of quality etc. and what should i use bearing in mind i want to: - always have a consistent quality to my delta, as i bulk roll, and should be getting every roll exactly the same except for what photos are on it of course. - as much reusability of developer as possible while maintaining good results. help guys? thanks.
