Can anyone dig out for me a b&w reversal formula for such as FP4? I found one
in a 1941 American Photographer magazine which referred to a formula in the
1941 British Journal by Andre Page and another in a photo chemistry book.
However, the instructions are not really clear and consistent. In order to
shoot positives with a 12x20 for photgravure, I have been buying a kit by
Ilford in France. It works nicely, quite, perhaps too, contrasty, but it costs
$25 to develop one sheet of 12x20, and it is not available in the US. There
has to be a better way.
