Re: About softening gelatin.

Hello Sandy,

Would swelling of the gelatin layer necessarily soften it?

I know that holographers have a technique for pre-swelling
gelatin layers in holographic plates by controlled soaking
in varying percentage solutions of Triethanolamine.
Triethanolamine or TEA can be found in the Photographer's
Formulary's chemical listings. It's also used a great deal in the
cosmetics industry.

best regards,

Phillip
