The reason I posted this is that I am coating in TOTAL darkness. I usually pour-coat ortho emulsions. But I cannot imagine pour-coating without some light. But I suppose that was what was done with the first commercial panchro emulsions. Of course, what helps one person may hinder another. I have found that the frames that I have made minimize bungling around in the dark. Also, taking ten slow,deep breaths between movements helps.
