This image has followed a tortured road. 4x5 film negative >
black and white photograph (Ilford Multigrade FB) > handcolored with dyes >
scanned to digital file > digital b&w negative and digital color negatives >
handcrafted silver gelatin emulsion > three-color gum printing.
( Note: I am working out negative manipulation guidelines. When I feel
comfortable that these are not totally bogus, I will amend this page to
include that information. Currently, I am employing standard gum
printing techniques of pigment v. sensitizer concentrations and exposure
timing, along with selective pigment removal during development. Which
of the time-honored gum techniques will
remain part of my personal work flow is yet to be determined. dwr:

As I have noted in pervious posts, the quality of the print doesn't quite
come through the scanning process. The tooth of the paper, covered with
gelatin and gum is beautifully smooth and reflective. The scan
looks much more matt and rough than the original.

One last go at 'Courage' for awhile. I decided to play with as many
manipulations as I could think of. 1) I made significant changes to the
B&W print. I lightened the sky to leave only a hint of the clouds and I
selectively lightened each cactus pad. 2) Added Q Gold to the
highlights layer. 3) Changed blue pigments. 4) Changed red layer
mix. 5) For a fifth layer, I selectively painted on sensitized
"Sap Green".
All watercolors and gum arabic from Daniel Smith. Potassium
dichromate sensitizer. UVB photo flood exposure.
