Did B/W printing in the past and now setting up for first time film developing hence another Newbe Question:
Re. mixing dev stop and fix quantities I get a bit confused as the tank supplier Paterson indicates a 290ml fill up quantity and info for mixing is indicated in many ways in a 300ml quantity for dev, stop and fix, even in Ilford brochures.
Do you fill up as the tank supplier prescribes or do you round up to 300ml?
