Hello! I have Ilford ID-11 film developer powder (says 1L on the box). So I can't figure out how to mix it. I found on the internet that people usually mix the whole thing with 5l of water. I am wondering what is the best way to do it? Can I mix it with 1L of water to make stock solution and then mix it with more water before developing film (for working solution). And if yes, what should the dilution be? It's my first experiment so I'd like it as detailed as possible please. For storage, I have loads of collapsible chemical bottles.
