hello! i was just starting to do some proper b-w photography and i got Fixer Kodak T-Max 1l and Developer Kodak D-76 for 3,8l in pouder. i was wondering can i use this products for both developing the film (negative) and photo paper (pozitive)? Or do i have to have a specific one for either of this steps or all that matters is the different concentration? Also any advice is very welcome and respected . have a nice day.
