Today I tried something a little bit different. To make a stock solution for 1 litre of dryplate ferrotype developer, I used 145g Dektol, 50g Sodium Sulfate Anhydrous, and 30g Ammonium Thiocyanate. Mixing a 1:1 working solution may have been a bit strong. It produced a somewhat overdeveloped image at 90 sec.. Tomorrow I'll try a solution of1 part stock to 2 parts water and see how it goes.
