Hello,
I am using 510 Pyro for one year now. Results are very good but I see that I am using times and temperatures much higher than the ones people have mentioned in forums. I dilute 1/100 and have used 23 C about 12 minutes for FOMA ASA 100 films 4x5 developed in a vintage glass 10x15 cm tray that I agitate a bit every 30 s. I use 100ml of working solution and develop one sheet at a time (I am not professional so quantities are manageable one by one). Could that be a problem with the film? When I started with 510 Pyro I think it was not that hot nor that long. As it is still my first batch of concentrate I wonder if it is expiring (although people also say that it is an "unexpirable" developer). Any similar experiences out there?
Thanks
