Re: Colored Dags?
In 2002 I met a modern practitioner of the Lippman process, Darren Green who resides in the UK. I have one of his Lippman plates and its beauty never ceases to amaze me. After a bit of searching I found an article that describes his process and I have posted a pdf of it on my website, you can view it at;
The paper also describes the Helichromes of a mutual friend, David Burder. I gather these are not Hillotypes but another process. These were on a copper plate and he would buff them with a cloth to improve image before viewing. Strange but true.
On the subject Of Rev. Hill's images - Bill Becker of the American Museum of Photography gave a very good presentation at a Dauerreian society conference a few years ago and in covering the History of the process mentioned and showed slides of the ones produced in the 1980's. The photomicrographs showed a colored crystalline structure, not an interference pattern as happens with Lippman images

Dear etienne Thank you very much for that clarification. Having seen more than 100 Lippmann color photographs which also utilise interference generated colors, I was quite certain of the additional facts you now mention in your current post. It is not surprising that one might have trouble reproducing and or viewing such colors. Now, to see some of these images, either originals, or somebody's recreation.... Does anyone know who holds these?
