There is a description of the process and some pictures on
http://www.plumart.com/vf2400/html/body_1124alfons.html
It is in French, but basically it seems to say that bichromated gelatin is
exposed and then washed and cooled, when the pigments are applied using a
very soft brush, being absorbed in pockets of water in the soft gelatin,
before being heated to 40 C to make the image final. I think.
Wasn't quite sure whether the last para should be taken as technical
information or not:
>"Flaque d'eau enrichie de rouge manganèse avance vers une coulure de vert
>malachite et se fait freiner violemment." Au réel de la photographie se
>rajoute le divin de la peinture.
