Re: lumenprints not chromo?
Jalo, I always called it "making BW paper POP" but that is not as catchy a title as Burchfield's "lumenprints" which is basically his plant forms put under glass on paper for huge amounts of time and then fixed--the same process. I notice in my notes he exposed some prints this way for 94 DAYS. I suppose the difference is I have used negatives with th POP process, not just photograms. How about POPhotgrams...

What would be the correct terms for lumen and such. Isn't lumen related to plant "shadowgrams"? "Invented" by Burchfield. A similar contact print from negative would be POP, or what? I'd like to know, because I need to explain this to students somehow... cheers, -Jalo \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ V E D O S Alternative Processes in Photography & Printmaking Satakunta University of Applied Sciences Faculty of Business and Culture Kankaanpää Paasikivenkatu 24, Box 76 FI-38701 Kankaanpää vedos@samk.fi http://vedos.samk.fi http://www.samk.fi ________________________________________ From: Christina Z.

There is a noticeable loss of density and color shift in the fix. I also know that Jerry Burchfield who does all those Amazon exposures brings all images back in a black plastic bag to the States and fixes at one time. Unless he has changed his process in the last couple years, all of his previous lumenprints were fixed and I have never heard of not fixing before...however, the idea to scan before fixing is a great one and then you get a two-for-the-price-of-one special. My prints do not fade once fixed and archivally washed and treated as if a normal BW print. You can see student examples on my website, and see how brilliant they are--with fixing. Re: scanning. I would find it shocking that a 90 day pinhole exposure lumenprint (chromo is a different process entirely because it uses darkroom chemistry, developer, activator, stabilizer) that will never touch the developer but go straight into the fix, would be affected by a one minute scan. You will also notice a distinct color shift when dry prints are rewetted. But then it reverts again when dry. Chris __________________ Christina Z.

Chromoscedasic print. The image looks good, but do I fix this? Maybe some thiosulfate? Or should I leave it? My plan is to scan it but will the light in the scanner affect the image? Scott B.
