Phil Harris writes: I have
in the past (about 1960) processed Ferraniacolor with the kit. I
even obtained Dufycolor films and processing kit when they closed
down and kits were being sold off cheaply, but never actually used
them, though a fellow pupil at school did, and the results were very
good.
I was born in 1940’s and
was a Barrister for 30 years, and I am now painting in the egg
temprta medium and researching various scientific and botanical,
especially dyes and pigments. As well as taking photographs, often
of flowers, using fantastic Superdrug colour film, I am still
interested in black and white photography and old colour.
Currently, I am obsessed by
the direct colur systems, not using dyes, but producing interference
colours, like the Lippman process or the alleged Hillotype process,
recounted in the New Scientist of 9th November 2002, whereby colour
plates were produced without dyes by some chemical wizardry. The
author’s book mentioned at the end of that article Banyard’s
Folly, contains nothing about this process, and is simply about a
series of American grandiose scams, which I think this probably is.
I can find nothing about it in the British Library. It seems to me
in principle extremely unlikely, though and American academic claims
to have followed Hill’s recipes and instructions and found that
the process works. Do any members know anything about it? I should
very much like to know.
