I used 2 liters of developer each time. I'm still new at darkroom printing - is Ethol LPD a good developer for a beginner to use?
Yes it is. The initials stand for "long lasting paper developer". It has an incredibally long life in trays and in bottles between uses. It can be used as a replenishable developer as well, and comes in powder or liquid(most prefer powder). The great point is tonal control via dilution without changing developing time. Mix 1+3 or 4 for warm tone or 1+1 or 2 for cool tone.
