Do you have any thoughts on how caffenol works, and how one might optimize this developer solution while keeping it non-toxic and ideally easy to create with simple household products? Or is Caffenol already about as good as it gets? On the caffenol website they don't seem to have link that explain the chemical process, but do mention that it's all about the phenols[0]. Which that in mind, wouldn't berry juice be a lot more effective?
