@babe I mean, I'm sure it will be reverse-engineered at some point, the question is: at what cost. obviously it won't be something that can be done by an amateur, the original process is 9 steps if you omit washes, and requires multiple re-exposures at specific light wavelengths to only re-expose one of the layers, with a lot of developpers that are toxic and need specific temperatures etc. obviously not credible to do at home. so even if someone reverse-engineers it... how much will they want
