Developing black and white film just got a whole lot 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 with this ready-to-use single-step solution, 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 exposed silver halide is dissolved by the fixation process before development can take place. Our monobath 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 redepositing it, to achieve crisp uniform grain and wide development latitude.
