    Default Sensor Questions


    Some Qs regarding images sensors on digital cameras.

    1) What actually happens when you select lower picture size (say, 3 meg) on a 6 meg camera? Only half of the sensor is being used?

    2) Whats the difference for the sensor in a compact and DSLR of the same resolution (8M for e.g.), other than the obvious sensor size difference?

    1) No, the internal image proceessor of the cam crops the image from full resolution to lower.

    2) Bigger sensor has less noise. iso1600 on dslr is comparable to iso200 or even iso100 of a PnS cam.
