I've been using coffee as a developer as part of a demo in a lecture that I give!! However, as far as using it for "serious" work, I don't!! As you can imagine dev times are a bit hit and miss - I rate FP4 Plus at 400asa and leave it in the "dev" for 30 minutes with agitation every 5 minutes - but I've left the film in for an hour!!!! With no ill effects!! I hasten to add that I use it just to prove that it works - not to print from. Top tip - I use a nice strong Columbian and dilute it with warm water 1:1.
