Direct Positive Reversal Prints On Regular Photo Paper

I was inspired by a video on instagram by Don Froula (@donfroula) a while back, he was making direct positive prints on photo paper that he was shooting in large format cameras. I love shooting paper negatives, and thought that this would be a great next step from that process. I had put this project on the back burner for a while until the Homemade Camera Podcast started a Self Developing Camera Challenge (homemadecamera.com E31 - the Afghan Box Camera). I thought that this would be a perfect time to dig into the process a little bit. Major thanks to Joe Van Cleave for his many many videos on the topic and for working out one of the major hurdles to the bleaching process that I am using. Without his videos and posts on Photrio/APUG, I would have never figured this out. I am hoping to share this process and see what else people start using it for, and what great work they will make with direct positive reversal prints. If you are really really interested in this, and want to take a deep dive, here is a selected bibliography of my research: Joe van cleaves original video that inspired this:    • Reversal Print Processing: A New Approach   Joe Van Cleave's video where he figures out the separation of the acid and vleacn in the bleaching step (note this is part 6 of a 6 part series - very interesting if you're curious about this sort of stuff):    • Reversal Print Processing - Part 6   Don Froula's iron out reversal processes:    • Iron Out reversal processing   Photrio thread all about the technical details. This thread goes on for hours of reading, but it is totally enlightening to watch a few people correspond over a message board over months to figure out a new chemical process. It's really one of my favorite pieces of technical literature of all time: https://www.photrio.com/forum/threads... Also, just go check out Joe Van Cleaves channel in general. It gets pretty typewriter heavy, but if you are into building cameras, he's got some of the best videos anywhere on the internet. I am a particular fan of his series on Agent 51's secret camera designs:    • Agent 51's Secret Camera Designs - Episode 3
