– here a
pigment print is created on the paper, then the paper is coated with
a photosensitive Van Dyke Brown emulsion.
Once dry, a contact
negative is placed on top of the pigment image which is then exposed
to light and processed in water.
The print is the
new fixed in a weak solution of hypo. The print is the washed in fresh
water for about 3/4hr. Van Dyke Brown emulsions produce dark brown coloured
prints - so they suit earthy colored subjects. Again a channel with
these darker tones can simply be dropped from a single image when pigment
printing and replaced with a Van Dyke Brown emulsion over print- or
the background can be printed from another image.
Where it appears
that exposed areas of the Cyanotype emulsion wash off the pigment print
- the Van Dyke emulsion tends to remain on top of the pigment discolouring
it, so you need to create dense areas on the negative where you want
the emulsion to wash off.
this contact negative the areas printed onto the paper with pigment
have been blacked out - this stops UV light effecting the emulsion
and leaves the colours in these areas vibrant.
of the image intended to be revealed as a Van Dyke emulsion can
be subtly printed with pigment by reducing the opacity of this
layer to about 85% in photoshop. This produces a combination of
pigment and Van Dyke Brown in these areas.
