I'm sure this question has been asked and answered before, and I just didn't search long enough. If a camera has a 4000 x 3000 resolution, and I select a reduced resolution of 2400 x 1800 or so, does the camera read only that part of the sensor, or does it read the full sensor then mathematically crunch the pixels to the reduced resolution?
I know it is recommended to shoot at full resolution, but I have an older computer that stumbles transferring larger files through the USB ports, and it was either a new computer or a new camera.

It reads the full sensor then mathematically crunches the pixels to the reduced resolution. It's a lot more complicated than that, but that's basically what happens.
Here's a pretty good explanation - »www.linkwitzlab.com/dpp/A-D-conversion.htm
SandShark, thanks for confirming my suspicions, and thanks for the link to the article. I think it will take me quite a few readings to comprehend half of what he is saying.
