Sports shooting High ISO Low light MK II HELP!

The most common cause of "excessive" noise in high ISO images is under-exposure.

Could you (or someone else) elaborate on this point? I need to shoot at an indoor swim meet this weekend and I will have to deal with higher ISOs. I am not familiar with exposure techniques for noise management.

Thanks,
Roger

When you under-expose a shot and then bring the exposure up in post-processing, the noise will be more apparent. If you nail the exposure and therefore don't need to bring the exposure up, the noise will be much less noticeable.

Noise can also be a problem if cropping into the image. Regarding exposure just make sure you nail it in camera to eliminate that problem. If its still a problem run the images through any noise reduction software as previously suggested.
