I have some outdated, but frozen-stored Fujichrome CDU duplicating film. Does anyone have suggestions on how to use this as camera film? All I know is that is has an EI of about 10, and is balanced for halogen lamps. I plan to process this by E6 or some equivalent reversal process. No crossprocessing in C41. I've clip-tested a couple of strips in E6 already, and the images came out too blue- likely because of its halogen-light balance. The contrast wasn't as low as I thought, it being a low-con duping stock. The EI 10 speed, loaded in an old rangefinder does give a feel of how it was to shoot in colour in the camera's day. Any tips and samples from anyone?
