Anyone else having problems with this stuff being really thin? I recently shot a few rolls of it in 120, and they curl like hell. I have to weasel them into my pages and then set them under a heavy book for a few days just to flatten them.
The Maco films are rebranded stuff, probably Efke 50.
The curling of the film is lessened with higher humidity and slower drying, from my experience. I think it has to do with the acetate base (or polyester in the 120 rolls) and the emulsion drying at different rates, and in a hot/dry environment the emulsion dries faster and shrinks, taking the base along with it, making the film curl.
