A faster card only helps the write time, and the difference would be so small as to be imperceptible. It would have no effect on exposure.
Exposure is strictly a function of the combination of ISO, aperture, and shutter speed. To gain a shorter exposure time means using a faster shutter speed. That can only be accomplished by changing the ISO and/or aperture.
Hi,
I was told that a faster memory card would allow me to use shorter exposure times. Is this true?
Thanks,
