5"x7" Platinum Palladium print on Arches Platine, coating the
paper 10:9:1 (Ferric Oxolate/Sodium Palladium/Sodium Chloroplatinate),
humidity at 65%, exposed 7.5 minutes.

The same 5x7 negative, processed as a Ziatype is shown here.

On a computer screen it is difficult to see any great difference between
the two images, however, holding both prints for viewing, the platinum
print shows more 'depth' and a slight but discernible 'glow' in the highlights.
