great thread !
ming, some caffenol folks ( over on flickr in the palace )
use salt in their caffenol developer to reduce fog ..
its fun to see other folks experiment with it ...
did you get a chance to print any of your experiments ? some
salty film looks better electrified, some looks better contact printed, and others look best enlarged
i guess the trick with film is to dovetail the whole chain .. film>dev> what type of print ...
don't stop having fun and experimenting, its when you get off the main road you see the good-stuff.
and don't listen to the nay-sayers, sometimes they just enjoy stepping on everyone's buzz ...
