Well, a book is a good idea, but hey, here's some of the little I know. You don't need a sink. I use big old coke bottles and let the sink sit over night till it hits room temperature -- that way you don't need a thermometer. Once you get a tank -- Peterson (Paterson?) makes a nice one that is plastic and is like a ratchet -- you don't need a darkroom either. I don't do much 35mm, but I used an old Photocopier Paper box cut two holes in it just as big as my wrists, put the tank and a bottle opener in the box, sat under the blankets in the middle of the night, and wound the film on the spool.(posted 8880 days ago)You don't need running water to wash the film either. Once it is developed, and fixed, just fill it with room temp.water and dump, and repeat 10 times. Then hang to dry.
This is the chemistry I use: Ilfosol S (Developer), Kodak Indicator Stop Bath, Ilford Universal Fixer, Hustler Wash Agent, and Photoflow wetting agent.
What is really easiest is to go to your photo-store -- a big one with lots of used equipment and people who look like they are there because they are addicted to film. And ask one of them. Don't go on a Saturday because they are busy. Go on a weekday when it's slow so they have lots of time. I learned all I needed to know from the guy behind the counter.
Good luck. Dean
