How to test a shutter
How to run ShutterDoc's tests, on video, starting with the Quick Test.
Quick Test
The quickest way to check a camera's shutter speeds: handheld, in normal light, in a few minutes. It measures speeds up to 1/60 on focal plane shutters and 1/125 on leaf shutters, so you can compare each one with what the dial says.
More tutorials and demos, for ShutterDoc's other tests, are coming soon.
