The platinum-palladium process was
developed in the 1800s. I began printing with this method
in 1998, and continue to this day. Because it relies on
contact printing, the platinum-palladium technique requires
a negative, usually made 'in camera', the same size as the
final print.
I do all my printing on 100% cotton fine art papers. These
are hand-coated using a light-sensitive solution containing
platinum and palladium metal salts. After coating and
drying, the paper is placed in direct contact with the
negative. Both are exposed to a light source rich in
ultraviolet. Finally, the exposed print is developed,
washed and dried. A properly processed platinum-palladium
print will last generations.
In early 2000, using Dan Burkholder's book as a guide, I started to
experiment making enlarged negatives with an inkjet
printer either from film that was scanned or directly
from 'in-camera' digital capture.
Since then I have tried many different methods and
suggestions. Until recently my results were, to say the
least, unspectacular. With the generous help from others on
the 'net' I have finally found a melding of equipment and
workflow that can produce satisfying negs for alternative
processes. Currently I use both Mark Nelson's PDN workflow and Ron Reeder's Quadtone
workflow for making inkjet
negs.
