Wow! talk about expensive. Actually I did try this method but with cyanotype
solutions. The results were not good. The gelatin layer readily absorbs
liquids, but not evenly. The trick is to get a really even coating.

I wouldn't know where to start to do this. Besides with such a nice,
uniform, quality controled gelatin layer already on commercially available
paper why bother?
