RE: Trick for increasing speed of photo papers?

I've been able to get an asa of 10 to 12 with Ryuji's DS10 developer using
Kodak CGP lith film. see http://www.kpgraphics.com/

To get this speed I need to flash the film - expose it to just below the
fog level.

See http://silvergrain.org/Photo-Tech/film-dev-recommend.html for the
developer.

CGP is available in a wide variety of sizes as well as rolls. I think its
possible to get rolls from something like 6 inches wide to 24 inches wide.

Could make some interesting pinhole panormic cameras using this film :)
