Hi Eddie - thanks this means a lot to me , I have been working on the solarized to Gum Pigment Idea for about 8 years now.
This negative is a silver gelatin negative to size, something very unique and exclusive to me and a lab in Germany... the film allows for greater blocking power, not so important
with gum printing , but I could use these negatives with Ilford Warmtone and the prints would be as nice as enlarging the original film.
