Works great with 35mm, 120 and any size SHEET FILM.



The most convenient black and white developer we know.  We use it here at New55 FILM.

R5 MONOBATH DEVELOPER is a universal all-in-one developer, stop, and fix solution for black and white photographic film.  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 well with the old-style cubic-grain emulsions like Panatomic-X and others common in the 1950s and 1960s.  We have tested R5 MONOBATH DEVELOPER specifically with our own Atomic-X 4x5 sheet film, Ilford Pan F+, HP5 Plus, Delta, Kodak TMAX, TRI-X, Efke 25, and Shanghai 100.  It should work with any black and white film, and has even been found to work well 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, R5 MONOBATH DEVELOPER is especially recommended.

DIRECTIONS FOR USE:  Wear gloves and eye protection, and use in a well-ventilated space. Warm the R5 MONOBATH DEVELOPER to 85° F (30° C) in an external water bath. In total darkness, quickly immerse your exposed black and white film completely in the warmed monobath.  For 35mm, 120 roll films and 4x5 sheet films in your daylight tank, agitate continuously for the first minute and for 5 seconds at every 30-second interval. Maintaining the temperature is key: avoid pouring the warmed monobath into a cold tank or tray; use more monobath than you need to cover your film in order to keep it warm. Remove your film from the monobath and rinse it thoroughly in room-temperature tap water for at least 5 minutes. A wetting agent is optional. Hang to dry.

1-Liter (32 ounce) plastic container.  Keeps for a long time and you can develop more than 400 square inches (2,500 square centimeters) or about 7 rolls of 36 exposure 35mm film in 1 liter before it needs to be replaced.
