I haven’t posted much in the last little while, been calibrating my platinum printing process with digital negatives and quadtone RIP using Ron Reeder’s new book. Highly recommended! I picked up a UV exposure unit with a vacuum frame for a song a few weeks ago and I figured it was time to standardize so I can get consistently repeatable results and a pleasing full range of tones in my prints. So far I’m pretty pleased with the results.
Testing out my recently acquired 90mm Super Angulon’s macro capability. Massive bellows extension, this was a 17 minute exposure at f32 in a bright room using available light — those are tiny snail shells. This is a square crop of the original 4x5 shot, printed on Arches Platine with Potassium Oxalate developer. I’m really loving the warmer golden look of the oxalate vs the ammonium citrate cool tone developer. (Three Shells, Platino-Palladiotype © 2011 18pct)
