If somebody manufactured gelatin dry-plates in the most common large format sizes, would you realistically buy/use them? I'm talking about a slow, color-blind, black & white emulsion on glass. Bearing in mind that you may have to find/fashion a glass plate holder and become accustomed to shooting with a material that is quite different than panchromatic (or even orthochromatic) stock. Assume for the moment that this product will be well made, reliable, expertly packaged & shipped, easy to purchase, and capable of producing very beautiful photographs. Yay or nay?
