I read on Dick Sullivan's blog the other day about the use of Fumed Silica and gave it a try. I have posted a short essay on Facebook about this easy process. I thought the results were worth sharing. I made the portfolio public so I think we can all see it even if we're not friended. http://www.facebook.com/media/set/?set=a.3157306927923.2148017.1122723189&type=1 Feel free to comment. Apologies to those who can't see the essay, here is a comparison of the difference. Image on the left, normal development process, image on the right, the use of fumed silica applied to paper before coating with metals.
