Am trying to take some action pix with the "S" wheel setting, 4000 shutter speed, bright daylight. Pix are coming out WAY underexposed (dark). I've tried reducing the shutter speed way down, several times to no avail. The aperture indicator keeps blinking. The manual says nothing other than to slow down the shutter speed.
Am I missing something.
Anything I should do/try? Manual doesn't go into any other suggestions regarding this problem.
