Hi Folks,
I was reading a review and the person said that as the ISO went up the pixel count when down. (two questions).
1) Does the camera actually lower the number of pixels as you shoot at a higher ISO?
2) If you stay at a lower ISO to Avoid problem (1), if you use a tripod and a longer exposure in lower light, a few seconds, do you get lots of noise and ugly clumping?
Thank you for the help
