    Bostick & Sullivan-- new developments in Alt Photo

    Ok, you'll have to do some detective work as I am not allowed to post links until I have five posts but you should be able to find them. Don't go to the old blog go to the new one that at the carbon works.

    If not email me and I'll email back the link to the blog.




    Fumed Silica

    Techniques developed at B+S: A finely divided quarts powder that that in liquid form or dry can be applied to art paper to improve dmax and resolution. Josh Partridge of the Cunningham Trust is now using it to print his grandmother's work.

    The Athenatype

    This is a silver process that uses guanidine ferric oxalate. A strong POP image, develops in water, does not bleach back in the fix, and is predictable in outcome.

    Included in this doc.

    The making of guanidine ferric oxalate and coating with silica

    Selenium-tungstate toner for metallic silver images

    This toner looks and acts like a gold toner. The colors run from a rich brown to neutral black to blue black with no yellow staining of the highlights that is typical of selenium toners. Made with a thiosulfate free selenium solution and a tungsten carrier. Stunning colors at a tenth the price of gold.

    We fully document, formulas and all, a new toner replacing gold, silica quartz sizing enhancer, and a new easy to use POP water developed, predictable silver process among other interesting items.

    Other new things include:

    A complete description of the making of Autochrome plates. Yes, how to make them, not just how to develop any you have laying down.

    A 1908 doctoral dissertation of the Lippmann Process. How to make full color images on a glass plate of a single layer of panchromatic emulsion. Lippmann got the only Nobel Prize ever awarded for a photographic process in 1908.

    Lots of other goodies as well as a few rants from me.

    Hi Dick, just introduced myself over at your forum this last week. That article you posted regarding toning cyanotypes with copper was quite interesting and I foresee experimentation with that soon. This new selenium-tungstate toner; do you have any prints in your shop done with this process? I'd love to take a look.

    Wow- very cool stuff! I will definitely have to give some of this a try. Question- do you apply the fumed silica prior to coating, or to a finished, developed and fixed print? Can you use it with any alt process, or does it work best only with specific processes?

    Great Blog and good name, "Swings and Tilts".
    I'm also interested in the fumed silica. One art supplier I checked wanted only $12 for a quart but $40 to ship.

    Not to be a wet blanket (and I say this with a smile) but the Autochrome instructions are nothing more than a basic description of their design. I was hoping for something really in depth.

    Quote, "Yes, how to make them"

    You got my hopes up!!
