Hi all,
Has anyone here tried heliography? Apparently this was the first photographic process, and the materials employed include bitumen of Judea (asphalt), and lavender oil for the washing. I'm looking for any information on the process. A quick search yielded this work: Heliography & physautotype : dabbling in pre-Daguerrean photographic processes / Howard F. Efner / El Gato Macho Press / 2007. I might be able to view this work at a nearby library.
I used to work at a geotechnical engineering firm that did extensive asphalt testing, so I probably have access to this material. I was thinking of using a non-traditional substrate such as a concrete slab, with a digital negative, exposed to the sun.
Any info is much appreciated.
Thanks!
