== Coffee-based Caffenol == | |||
* Smells extremely bad, avoid doing this again until the darkroom has improved ventilation. | |||
** First two 8x10 prints came out great, then there was an hour delay due to other things coming up, then we did two prints that were very dark and very low contrast no matter what we did. Unsure if it was the time delay causing the developer to break down, or that it was exhausted after two sheets. | * Tones the paper slightly sepia-like | ||

== Green tea-based Caffenol == | |||
* Worked great, doesn't smell nearly as bad as the coffee-based solution. | |||
* Developed 5 sheets over an hour or so and no noticeable degradation over them. | |||
* Despite looking like a green milkshake, doesn't noticably tone the paper at all. | |||
