I have several antique cameras that I've restored that I would like to use in my photography. Many of them have focal plane shutters capable of speeds up to 1/1000 (Graflex cameras) but in order to use them seriously I need to test whether or not the shutters are performing at the marked shutter speeds and if not I need to adjust them. I've read articles from back issues of old photo magazines describing a method of testing shutter speeds above 1/60 by photographing a television screen and counting the lines on the film. The method is purportedly very accurate. Here is a description of the method from the Dec 1967 issue of Popular Science.
Now, does this method work with modern televisions i.e. plasma screens or LCDs? I understand the description of how the image is made on the screen but I'm wondering if this is only true for older televisions and if this is no longer a feasible technique with digital televisions. If anyone has any information on this please let me know. In the meantime I think I'll start building a small shutter speed test as described on Jo Lomman's website here.
Any insight into the best way to go about all of this would be very helpful! Thank you.
