I have been experimenting today with developing cyanotypes in a
solution of water and vinegar. The proportion of water to vinegar is
five to one. But then I read that you should not mix potassium
ferricyanide and acids, because the former might release cyanide gas!
Does that mean it is not really safe to develop cyanotypes in vinegar
water?
