Silver Halide Film vs Chemistry vs Hologram Type
Described here are sucessful chemistries to use for each qualifying film for a particular type of hologram. For specific formulations look at Silver Processing Formulas.

Single Beam Transmission - Film vs Chem
PFG-01
For low frequency gratings, use develop reversal bleach or develop fix rehalogenate, for if the fringes are too far apart the "swim" of the materials from one fringe to the other is too far and not much modulation occurs. I discovered this when I made a low spatial frequency grating (the fringes were about 30 line pairs per mm, as you could see them with a strong magnifying glass) and the transmission grating was weak, but the single beam reflection holo of the back side of the glass (the dreaded woodgrain) was decently bright! I switched to develop/reversal bleach and painted the back of the plate back to fix things up. (Ed Wesly)
Single Beam Reflection - Film vs Chem
PFG-01
(Ed Wesly)- Replay in the same wavelength use CWC2 developer with PBQ rehalogenating bleach
(Ed Wesly)- Replay is color shifted use Pyro or CWC2 developer with Dichromate reversal bleach
Replay in same color use JD3 - Integraf
Replay shorter use JD2 - Integraf
PFG-03
(Ed Wesly)- Replay is same wavelength use Slavich Hardener with G2 Developer and Slavich Fixer
BB640
(Ed Wesly)- Replay in the same wavelength use Pyrogallol based developer with Rehalogenating bleach
H1 Transmission - Film vs Chem
PFG-01
(Ed Wesly) - Replay in the same wavelength use CWC2 developer PBQ rehalogenating bleach
Another case is for low frequency gratings, use develop reversal bleach or develop fix rehalogenate, for if the fringes are too far apart the "swim" of the materials from one fringe to the other is too far and not much modulation occurs.
