This is a negative image, printed on Platinum\Palladium paper.
I am currently searching for a silver paper that will give a similar look - I don't want cold B&W tones in the print. I would like to get a warmer even partly sepia tone to it. Then I will bleach the print to bring out the whitness of the spines. I will want to hold detail on the far gight, but still print it dark.
