Mitsubishi Imaging, Inc. is running a sale on the Pictorico line of paper and transparency film. I use the Pictorico Ultra Premium OHP film for making daguerreotype contact prints.
You can use this film for any number of alternative processes that require same-size negatives or positive transparencies. Platinum, palladium, carbon, Kallitype, Vandyke, Cyanotype, and tintypes come to mind just to name a few… 
The sale goes on until 8/31/2008 and there is no minimum. The discount is a very friendly 20% off if you use the discount code ANN08 during checkout. So go stock up!
