Collodio-Chloride Printing out Paper (POP) and orotones

Just found an interesting variant of printing out paper (a photographic print on paper that does not require a development stage, i.e. the image appears during exposure to e.g. sun- or UV light).  The albumin print is another variant which uses egg-white (albumin). This particular version uses collodion rather than egg-whites.

Interesting in the sense that it is supposedly quite archival, and I should have most of the required chemicals already. So might be a nice thing to try out at some point in time, once I figure out how to create negatives and find a decent paper…

Another thing to look at, is a means to create orot0nes with liquid emulsion :
