I was gifted a 1 gal jug of Ilfotec DD developer (not sure of it's age). I know it's for machine processing with replenishment and normally requires a "starter" solution. But the data sheet does have instructions for use without the starter chemical. Tried a clip of HP5 to make sure it was still good. Used the times for iso 400, but I exposed at 320 as I normally do. The negs seem a slight bit dense but quite usable. I can dial in times based on my agitation procedure. Any information on use in small tanks? And in particular, capacity? Based on the data sheet I should be able to reuse with a slight increase in development time. But not sure if this would apply to use in small tanks.
