Two of the most commonly used developers in the Platinum/Palladium processes are Potassium Oxalate and Ammonium Citrate. Potassium Oxalate is preferred for several reasons. It produces warmer tones, it does not become exhausted but can be replenished as needed and used indefinitely, and it can be used with the dichromate method of contrast control.
