bought a 1949 BJP Almanac ........... in it there's an advert
for Johnsons ColourForm, a colour developer/colour coupler system
for toning etc. Ian adds "I've used the same process but from raw chemicals and Bob Carlos Clarke used the Tetenal version for many of the images in (his 1985 book) The Dark Summer". An article on Using Colourform, from 'Practical Photography' magazine, July 1962, can be downloaded here. |
