This picture asked for a high contrast, something that’s a bit difficult to produce in palladium-platinum prints. I again went the digital negative route, and made sure to use the OHT’s whole tonal range with a levels layer. Then I used a different paper for the print, this time it was Arches Platinum, whereas here I used Kozo paper. Arches Platinum gave clearer highlights as well as deeper blacks. Must look into this, it could well be that Kozo paper is buffered and needs to be prewashed. The amount of contrast agent (Ferric Oxalate Solution #2 from Bostick & Sullivan) made the least influence on print contrast, that’s for fine adjustments.
