Photo Developing Using the Gum bichromate Technique

Gum bichromate is a 19th century photographic printing process based on the light sensitivity of dichromates. My courses are in Austerlitz and Amersfooort in the Netherlands. For more info visit my site: http://www.rogiervanderkruk.nl

I live in England, so sun is not an option ;-) Sunbed lamps, which means are they used for SAD(Seasonal Affective Dissorder) , also called phototheraphy treatment unit? Can I use that lighting source instead?

Thank you very much for all the helpful videos

, very useful for a student like me.

@coolnsblue1 No, just normal philips sunbed lamps. You just need a very bright light source.. sun is also good option.

Thanks. That was a wonderful overview. I remember seeing the work of a French photographer once- I think he used a process similar to this. He took pictures of various animals. Wish I could remember his name to see if this is the technique he used.
