510 Pyro was developed by Jay DeFehr. It’s a simple developer that keeps indefinitely and can be used at many dilutions – usually 1:100 – 1:500.
|Warm triethanolomine (TEA)||75 ml|
|Ascorbic Acid||5 g|
|Triethanolomine to make||100 ml|
I usually make 4 times this amount because it is easier to measure. I buy the pyro premeasured at 100 g, so I don’t have to worry about pyro dust.
