This was shot on digital. This particular camera had a top shutter speed of 1/8000th BUT although, in theory, the ISO could be set to (I think) 800, the quality was pretty poor at this setting and so it just wasn't possible to use high shutter speeds in poor light. The great thing about this camera was that it could get wet and still work.
Just 2 or 3 years earlier, most digital cameras were pretty unusable above 100 ISO. Most of the "professional" 35mm film cameras could go to 1/4000th or 1/8000th but again, 35mm quality wasn't great at 100 ISO and pretty terrible with faster films, and this limited usable shutter speeds in poor light.
