Re: lumenprints not chromo?

[Gregg Kemp <gregg.kemp@gmail.com>]

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?
