Fixing or desensitizing ultra-fine grains emulsion ?

Post by thycore »

I’m reading this astonishing book from H.I Bjelkhagen about silver-halides processing and I came to chapter 4 where it is discussed possibility to somehow fix or de-sensitize a developped hologram.

Fixing with thiosulfate,
Or
Desensitizing with Phenosafranine

In my quest of producing reflection holograms for display purpose, which one would give best diffraction efficiency ?

Thanks !

In that case I'd definitely switch to a rehalogenating bleach...
