Hi, I'm a 16 year old film photographer. I've grown to be sick of paying a lab to develop my film. I just purchased a Paterson system 4 tank and all the jugs, etc. The guy who sold me the equipment had some old chems he gave me. I have Rodinal developer (the original from Agfa) that was opened in January, 2005. I also have some Ilford Rapid Fixer that was opened in 2006 and some Ilford stop bath that has never been opened but was most likely purchased around the same time. My question is will any of these un diluted chemicals still work enough for me to practice with my first roll of b/w film? Also I'm in Victoria, Australia, how do i dispose of exhausted chemicals? Cheers, I look forward to using this forum as my passion for film increases.
