According to the posting on the Logitech forum<ref name=logiinfo /> exposure is equivalent to shutter speed and gain is equivalent to ISO.

  Exposure:    1/1000 [s] (-) <--------------------------> (+) 1/5 [s]

  Gain:                  0 (-) <--------------------------> (+) 10,000

Could this be used to capture even higher frame rates, i.e. theoretically up to 1000 fps?

The possible frame rates for a given resolution depends on the pixel format (see Pixel formats). There are both fortunate and very unfortunate differences when compared to the older (and cheaper) Logitech Webcam Pro 9000. One one hand, the C910 can no longer capture 720p 30fps using YUV formats (bad), on the other hand it can capture at 60fps up to VGA resolution in all but YUV 4:2:2 format.

Worst thing in the package is the accompanying Windows software, which limits the frame rate to 15fps[1] (at least at 1080p) –

HD resolutions that can do 30fps are marked in red. VGA resolutions that support up to 60fps are marked in green.

Notes

Higher frame rates

According to the posting on the Logitech forum[1] exposure is equivalent to shutter speed and gain is equivalent to ISO.

 Exposure:     1/1000 [s] (-) <--------------------------> (+) 1/5 [s]
 Gain:                  0 (-) <--------------------------> (+) 10,000

Could this be used to capture even higher frame rates, i.e. theoretically up to 1000 fps?
