I’m afraid this post is nothing but a list of links to various, from-scratch, silver-gelatine, emulsion recipes from around the web.
- Kitchen Lab Emulsions
- Gelatin History
- Silver Gelatin Emulsions
- Film Emulsion
- The silver gelatin dry plate process
- Homemade Photo Emulsion
There appears to be some variations of formulation in these recipes, suggesting there is latitude for error and experimentation. I’ve recently become interested in DIY photochemistry, and will have occasion to use a large-format camera for course work, so yeah, the gears are turning.
The bigger challenge would seem to be the acquisition of chemicals.
