whooo, I've done it! I've finally written up the blog post about the ink print process, an apparently forgotten positive black and white photographic process from 1880!

#InkPrint #Cyanotype #photography

ok, trying the ink print formula in camera for the first time today. obviously it's cloudy and raining today…

#InkPrint #Cyanotype

ok, time for more #InkPrint bullshit. gonna first of all test the pH of all the different sensitizers and then also just stick them in my photoreactor to see what happens. Might also just check pre/post exposure reactions with different developers like ink print or cyanotype

ok, all set up to test some more 1880s photo chemistry!

Gonna test all my variations on the ink print process to see what's going on with that

#Cyanotype #InkPrint

ok, more #InkPrint experiments. Prepared a bunch of new variations on the original recipe using different sources of Fe3+ (ferric chloride, ferric sulfate, and mixtures of both) and different acids (oxalic, citric, tartaric and maleic). Once I have the energy I'mma coat them onto some paper and do text exposures. I'm especially curious to see what's going on with the mix of ferric sulfate and ferric chloride in the original recipe and if that actually does something

Wheeeeeee! That's a lot better! Could have probably exposed for a little longer but it's still really nice!

ok, so, the diffuse light box definitely wasn't the ideal choice, barely any contrast there. probably also overexposed. maybe closer to 20 minutes would have been better?

I think I'm gonna try this again with my remaining piece of paper and a spotlight this time to hopefully get something more interesting

#InkPrint

photogram time!
