Developing black and white film became much simpler with the CineStill Df96 Monobath. The worries of too much development, dilution, time, or agitation are gone. Stop bath? Fixer? Hardener? Gone the way of One-Hour-Photos and formaldehyde. Finally, foolproof at-home film processing. 

Many of the pitfalls and hazards of a multi-bath process are eliminated, such as improper dilution, over-agitation, bubble marks, surge marks, etc. Over-processing is impossible because the fixing action overtakes chemical development while aiding physical development, creating better image uniformity and finer-grain negatives.

Monobath solutions were first proposed as far back as 1889, but only recently have the difficulties associated with their formulation been possible to overcome. The main problem has been the loss of emulsion speed that results when the fixation process dissolves the exposed silver halide before development occurs. Our mono bath is unlike home concoctions or old technology that failed years ago. Df96 uses a more effective processing technology (akin to D96 motion picture developer) that buffers fixing and archival fixing agents that are more solvent and aid in breaking down the silver and re-depositing it to achieve crisp, uniform grain and wide development latitude.

Fully Archival Processing:

Df96 uses one of the most influential archival fixing agents and will produce fully archival negatives in 3-6 min. With proper care. Extending processing time to ensure complete removal (fixing) of undeveloped silver halide will not affect development. Washing time after Df96 processing is exceedingly rapid because the solution is alkaline. Five minutes of washing is sufficient to achieve archival standards. This self-terminating process is fully archival and boosts shadow development while terminating highlights from over-processing.

Cost Effective: 

1000 ml of reusable mono bath solution will quickly develop 16+ rolls of film. Simply pour the used chemistry back into the bottle and add 15 seconds for each roll previously processed. 

Process All B&W Film:

Df96 mono bath works with any black and white film and is designed for traditional cubic-grain emulsions with high silver content, like BwXX and TriX. All films can be pushed or pulled by adjusting temp—+/-10°F per stop.
