Fixing Auto-Developed Photo Paper?

[Joe VanCleave]

I made an auto-developed photogram of a leaf, onto grade 2 RC paper, with the leaf sandwiched between paper and glass, exposed to noonday sun for an hour or so. I love the colors resulting in the image, and hurriedly scanned it, and have it now stored away in light-tight protection.

I'd love to somehow preserve this photogram and its colors, but am not sure if it's possible. The image results from the property of silver halide emulsions to auto-develop, given sufficient exposure. If I fix it, will the image disappear?

PS: The vaporous appearance above the leaf was most likely due to the frost covering the leaf was slowly evaporating in the heat built up under the glass, it being angled toward the sun and the vapors rising above the leaf.

I can't say for sure if this will work, but I'd be inclined to try this: (there was a url link here which no longer exists). It reportedly works on solargraphs, which are sort of like pinhole autodeveloped photograms.

Thanks for the link, I'll try it and post my results.

ME Super's link is what you need.

i have been making photograms like this for a while now
you fix them, even in excessively dilute fixer, they disappear,
you fix them in dilute hypo they disappear,
you fix them in carbonated fixer, they disappear ...
weak oxidized, black developer, the turn black ..

excessively weak spent caffenol full of washing soda and some have survived ( sort of )
nedL is quite a wizard figuring out how to preserve this sort of stuff,
beautiful image joe!
i hope it works

Gold toning seems to work well, though I haven't tried it myself.

Wolfgang Moersch seems to have had good results using both toning and "fixing" in Chromoskedasic stabiliser (and sometimes both). Have a search of his photostreams on Flickr and Ipernity.

I think the formula he uses for the stabiliser is

Water -- 750ml
Ammonium thiocyanate -- 200g
Sodium metabisulfite -- 70g
Acetic acid (5%) -- 340ml (I can't find the 28% figure but it's easy enough to work out)
Water to 1000ml

Dilute 1:4 for use

Never heard them called "auto developed" before
