Steve Spicer (Australia) and I sell those - free samples to anyone
interested!

I got this idea from rec.photo.darkroom some time ago. Basically, it uses
the fact that Tech Pan has a steep contrast curve very similar to normal
printing paper, when you develop it in Dektol.

Two side-by-side Sputnik images -just- fit on a 4x5" sheet of Tech Pan.
I did a first exposure as a test strip, doing 4-5 bands of 5-sec exposure
each. From that I was able to pick an exposure I liked.

Develop in Dektol about 2 minutes (as in printing papers, the time is not
very critical), stop and fix as usual.

This week someone on r.p.darkroom described doing the same thing with
"Arista litho film" from Freestyle Sales, Inc. - they said they were able
to successfully alter contrast by using different dilutions of developer.

Of course, this isn't limited to 4x5 sheets; but 4x5 is really convenient,
as you can tray process it in the same session as doing other printing. But
you could also use the technique with a slide copier for duping 35mm negatives
into positives for Realist format, for example.

Any more specific questions, please let me know!

Joel.
