I recently brought up a thread on LFF about coating Dry Plates by hand, thinking that since the subject hadn't really been addressed there would be great interest. It landed with a quiet thud. But, I wasn't surprised. Since learning to coat plates I've perty much lost interest in using commercial film, which has been to my benefit. I would have no problem making my own emulsions if I could justify the labor and time that is required. Cost wise it seems to be about the same a using Liquid Light or an equivalent.
