I've only ever processed one roll at a time. I'm going somewhere this weekend and plan on taking 5 rolls of 120 and 1 roll of 35mm. All HP5 except for one fine grained film, like the ilford pan 50. The 35mm roll I plan on processing it as normal with rodinal. 2 rolls of 120 pushed to 800 (microphen maybe?) for indoors without a flash. 2 rolls of hp5 processed as normal. and 1 roll of pan 50 Question is what can I reuse? How would you handle a situation like this. I'd imagine I could reuse the stop-bath and fixer without a problem.
