Sixty ml of HCL per litre is a 1.58% dilution, slightly higher than the
normally recommended clearing bath for pure palladium prints. As HCL is a
solvent of pure palladium, perhaps the warm image colour is due to the
erosion of the size of the palladium particles ....similar to the brown
image that results when one gets carried away when bleaching a silver
gelatin print in "Farmer's reducer"?
