Photographers’ Formulary TF-5 Archival Fix
The TF-5 Archival Fix is a non-hardening fixer with very little odor if mixed with distilled water. Works with film and paper processing. It is a near neutral fix that will change the pH of the film or paper from alkaline to near neutral. No stop bath necessary; use water rinse after developing. No image bleaching effects, which may provide richer blacks to your prints.
