I’ve still got a few ORWO NP 20 and A49 developing kits, each containing 2 litres. Does anyone know how many rolls of film (135/36) you can develop in 2 litres of A49? ? ? Sandro

Although I do generally use it as a single-use developer in dilutions of 1+1 or 1+2.

Depending on whether you’re developing more 100-speed or 400-speed films, you can develop up to 15 rolls in 1 litre. With a 1:1 dilution, I also turned the one-shot into a two-shot and extended the second development by 2 minutes. A49 is incredibly economical, even though it doesn’t increase speed.
