Prokudin-Gorskii's images are fascinating, but he didn't use Lippmann plates. Gorskii took three images using red, green and blue filters. That was also much more practical, because I don't think you can reproduce Lippmann plates, while you can print a positive RGB image with CMY(K) dyes. That's why they're CMY after all (cyan absorbs red, magenta absorbs green, yellow absorbs blue).
- throwup238 2y agoThank you for the correction! I didn’t realize that there were multiple different plate emulsion methods.
- jazzyjackson 2y agoThis is the first I'm hearing about this lack of reproducibility, I can't make sense of it, you could always just take a picture of the resulting plate, no? Except color photos weren't a thing yet, so there just wasn't the technology at the time to make multiple copies?
- ajb 2y agoSounds plausible. A the start of the photo era, the state of the art for illustrations was for them to be drawn by an artist and then engraved on a wood block, manually, that was then used as a printing plate. There was a period when no method was available to convert photos to printing plates, so from that period you find prints of photos where someone has manually copied it to a wood engraving for publication.
