This video is very cool to watch. I love that his work room is messy like mine.

I've tried Carbon not using dichromate and I've had very few successes so far. Using ferric ammonium citrate and oxalate, it has been such an elusive beast. But in the way there I've pit together my own cyanotype on anything formula and of course figured out how to use a dlp projector to expose images. All my negatives are basically just files.

I have dichromate but I'm afraid of using it. I work with aluminum components that get plated in various ways and a guy who used to work in the processing using dichromate died of cancer recently. Hexavalant chrome in conversion coatings is practically the same as dichromate. It seems harmless because its diluted but its definitely not. If I try it I'm gonna be using gloves and PPE.
