The Fine Art Collection is a limited Cibachrome print collection signed by the
author. The prints are made by Roland
Dufau, one of the best handmade
Cibachrome printer. A steady value to collectors and museum conservators.
Each
print is unique and numbered (edition of
9 or 30). The price of each print depend on the size ( from 12 x 16 to 24
x 32 inches ), the number of print already made and the frame.
The
shots were made with large format camera on Fujichrome RVP film. The Cibachrome
paper used is Ilfochrome Classic - CLM - 1K. All colors of the slides come from
the nature light.
Note : the images on Internet can not reproduce the subtleties of colors,
transparency and
fine detail of the slide ( jpeg format, monitor setting, Digimarc
Copyright, ... ). For your convenience and help you to take a
decision, a 13 x 18 cm proof can be realized on Cibachrome paper (not numbered).
In most colour processes, colours dyes are formed during the
chemical treatment. Impurities inevitably appear during chromogenic processing. This is
not the case with Cibachrome. Colour dyes are incorporated into the sensitive layers of
the material during manufacturing. The main advantage of this technique is that the purity
and the light stability of these dyes can be strictly monitored. Control of these elements
give Cibachrome its unique qualities. Once exposed, the sheet of paper is processed ; the
final colour rendering depends on the amount of dyes destroyed during processing. Yellow
dyes, for example, are destroyed to produce the blue parts of the image.
Principle of
silver dye bleach : The structure of the emulsion is identical in all colour processes.
Silver halide crystals are incorporated into three blue, green and red sensitive layers.
In chromogenic processes, yellow, magenta and cyan dyes are formed with the help of colour
couplers incorporated into the layers ; the dyes are formed in proportion to the exposure
received (blue, green and red light respectively) to restitute the colour of the original.
In the case of Cibachrome, dyes of azo type (yellow, magenta and cyan) are already present
in the emulsion in a saturated form ; they are destroyed during processing, in proportion
to the quality of complementary light received (blue, green and red light respectively),
that is in proportion to the amount of silver formed in these three layers.
A main feature of a Cibachrome print is its outstanding colours, with an estimated
permanence of more than 300 years (Kodak study 1989, Sciences et vie magazine).
This make a favourite amongst artists, exhibitors and collectors. Excerpt from Roland
