Cinestill Df96 Monobath
Single-step monobath that develops and fixes simultaneously. Temperature controls contrast rather than time. Processing over 28°C pushes negatives, below 20°C pulls density. Requires good agitation and temperature discipline.

Limitations & Warnings
- Greatly increases grain and contrast vs traditional developers
- Temperature-sensitive: above 28°C risks reticulation, below 20°C causes underdevelopment
- Early batches had reticulation issues — ensure proper temperature control
- Not archival-grade compared to separate dev/fix
