Developer Formulae

The developers were to his own formulas because that is what he learned from his early years with George Nakash and John Garo – no Kodak packages. For negatives, he used special chemicals that allowed a faint green light to reveal the deepening densities so he could judge each one individually. For prints, he had two developers, “hard” and “soft”, and sometimes both would be used on the same photograph – one to bathe the print, and the other to be applied in specific areas with a piece of cotton.
