Works great with all black and white negatives, from 35mm, 120, or any size SHEET FILM.


The most convenient black and white film developer we know.  We use it all the time at here at Famous Format.

FF No.1 MONOBATH DEVELOPER is a universal all-in-one developer, stop, and fix solution for black and white photographic film negatives.  It can be used in the field, in the darkroom, in your bathroom, or in a dark-bag to conveniently develop your black & white negative film in a single pass.

This monobath works with any panchromatic black and white film negatives, and it works especially well with the old-style cubic-grain emulsions like Panatomic-X and others common in the 1950s and 1960s.  We have tested FF No.1 MONOBATH DEVELOPER specifically with our own Atomic-X 4x5 sheet film, Ilford Pan F+, HP5 Plus, Delta, Kodak TMAX, TRI-X, Efke 25, Ferrania P30, CineStill bwXX and Shanghai 100.  It should do a great job with old exposed black and white film that has been sitting undeveloped for years. For that mysterious roll of film that came inside your new, old-timey camera, FF No.1 MONOBATH DEVELOPER is especially recommended.

Perhaps you remember R5 MONOBATH DEVELOPER, which needed to be warmed to 85°F? Well, FF No. 1 MONOBATH DEVELOPER is an evolution of R5 except that FF No.1 works at room temperature (70-72°F) and in most places does not require warming. 


Wear gloves and eye protection, and always use FF No.1 in a well-ventilated space. For best results with 35mm, 120 and 4x5 film, use a daylight tank.

1) Quickly pour the monobath at room temperature (70-72°F or 21-22°C) into your daylight tank. Ensure that the negatives are completely covered by the monobath fluid. Agitate using the inversion method continuously for the first minute, then invert once at each subsequent 30-second interval. Total development time is 6 minutes.

2) After 6 minutes in the solution, pour the monobath back into its container. Then rinse the negatives thoroughly in room-temperature water for 5 minutes.

3) Hang the negatives in a dust-free environment to dry. FF No.1 may be used again and again. This 1-Liter bottle develops about 400 square inches of film:

 35mm (36 exposures) 7 rolls
120 rollfilm 8 rolls
4x5 sheet film 20 sheets


Dealers' Case includes (9) 1-Liter bottles - 25 lbs. PLEASE SELECT "UPS Ground" AT CHECKOUT.
