RA-4 Direct Positive Reversal Process Update - Large Format Friday

After months of not making progress on a project I'd started early 2020, I found some inspiration to chip away at the RA-4 reversal process. You can see more about my start in this process here: https://youtu.be/M34136M-8NU RA-4 is the name of a color process intended for taking color negative films and printing them in the darkroom as a color positive. With some heavy filtration, a bit of patience, and heaps of light, we can actually expose this paper directly in-camera and specialty process this paper as a color positive!
