My attempts at using fixer with similar multi-day pinhole exposures resulted in the image pretty much disappearing off the paper. I used Arista fixer at normal strength and diluted as much as 1:20, but always lost most of the image. Perhaps a different fixer would work better?

I also had problems scanning at first, but that may just be my scanner (an Epson 3200). I found that if I scanned a 5x7 negative at more than 600 dpi, the scanner would pause during the scan. And the scan would show a slight darkening after the pause. So I now scan at 600 dpi. But perhaps a scanner with more memory or more memory on my computer would not do this. My suggestion is to scan a plain piece of paper at the resolution you plan to use before scanning the actual negative, just to be safe. I also put a piece of black felt behind the negative before scanning, in hopes of keeping down the amount of light bouncing around - just superstition perhaps.

Chris - I looked for the student work on your website that you mentioned, but didn't find it. Would you please post the URL?

I always fix mine. 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.

Just completed a 90 day pinhole exposure on gelatin silver paper. 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?
