Leaf shutters MAY not record one entire sweep at this speed if they start halfway through a picture trace (raster return timing). Most pro recommendations for shooting from TV screen (using 35mm focal plane shutter camera, normally sold by all mfrs.) are as follows: 1/8 sec shutter at f8 aperture using ISO/ASA 400 color film. Obviously, brightness of TV image can affect this setup, but be sure to go to the overexposure rather than the underexposure side if unsure (The final print will be properly adjusted by the printer). If you are shooting Black & White (Tri-X 400 ASA) use a red filter to compensate for color sensitivity of B&W film (CC40R filter). A tripod is required for this setup and unless the action is extremely fast, shoot from running picture frames, NOT FREEZE FRAME. Lens used should be between 100mm and 200 mm on 35mm camera. This will give best perspective rendition. The room should indeed be darkened so that there are NO REFLECTIONS on the TV screen that can make their way into the picture. Be sure to set the tripod up SQUARELY in front of the TV picture tube to keep distortions out. I have used this method and have been very pleased with the final results. Good luck.
