Larry DuBois Posted August 18, 2004 Share Posted August 18, 2004 Our company is in very short supply of 16mm frosted film that we use for focusing our cameras. Could you point us in the right direction in where we could find this film? Is there a way making this film ourselves? Any and all ideas would be greatly appreciated!

Mitch Gross Posted August 18, 2004 Share Posted August 18, 2004 Frosted film? Do you mean clear leader or perhaps white leader? If you want clear, simply take any film and run it through some bleach. If you want white then a place like Christie's or Rafik in NYC can sell it to you by the roll. How on earth do you use this to focus a camera? Do you mean a projector?

Larry DuBois Posted August 18, 2004 Author Share Posted August 18, 2004 This film is basically clear film, but has a coating on the emulsion side that allows an image to be projected on it, similar to frosted glass. We use small sections of the film and place it at the image plane, then a bore sight that is mounted on the camera is used to look at the image projected on the film to focus and align the camera. These cameras are old, Nova high-speed units made by Photo-Kinetics. They use a rotating prism instead of a shutter mechanism. Top speed is 40,000 frames/second.

Premium Member John Sprung Posted August 19, 2004 Premium Member Share Posted August 19, 2004 Is there a way making this film ourselves My hand crank camera lets you compose and focus using "frosted" film. The pressure plate latches in a position that puts an aperture in it behind the actual aperture, and with frosted film in place and a black cloth over it and your head, you can work it sort of like a big view camera. I made frosted film for it simply by soaking the emulsion off of 6" of scrap, then grinding one side with a paste of wet kitchen cleanser. It works fine. -- J.S.

It works fine. A dilute warm solution of sodium hypochorite laundry bleach ("Clorox", "Sunny Sol") will dissolve gelatin emulsion off film, leaving only the clear base. Be sure to squeegee and rinse well afterward. Link to comment Share on other sites More sharing options...
