So I just picked up a Unicolor C-41 kit (2.0L) and Arista development tank. On the instructions in the Unicolor kit it says to add the powder to make a full 2L of solution.
My question is, is it okay to mix smaller quantities of the powder? For example I will be processing a lot of 120 film and on the bottom of my development tank it says for 120-220 film the capacity is 550cc (20oz).
Can I mix smaller quantities of chemicals so I do not have to make a full 2.0L worth of developer, fixer, etc all at once?
