Photographic Processes - (Hand

Special
effects with alternative photographic processes
Multiple
exposures, moving or changing negatives between exposures.
Multiple
coatings of sensitiser - exposing and processing and drying between
coats. · Use different negatives, varying exposure times, etc,
for the different exposures or coats.
Layers
of gum bichromate in different colours, using different negatives and
so on, may be added on top of the processed and dried brown print. For
best results with registration, pre shrink paper by wetting it in warm
water for several minutes and letting it dry before the first coating.
Line up negatives the way you want them and make registration marks
with pencil or tape on the paper before making the first coating. ·
Coat
sensitiser over wax resists or crayon drawings. Try coating small areas,
spattering, or painting designs with sensitiser. Spattering may be done
with an old toothbrush or airbrush.
Cynaotype over pigment prints
Wear
an apron; and rubber gloves and goggles for messy or close work. Clean
up spills and spatters in the area as soon as you are finished. These
can cause permanent stains.
Coating methods, exposure and processing times may vary; and it might
be difficult to get good results with very porous or very smooth, hard
surfaces; so experiment with small test images first!
