sorry...they\'re terms used in the proceesing of "film"...(that\'s what we had before digital cameras...) I used to do a lot of my own developing when I was in high school (in fact I also got laid in the darkrrom there)...
I see. I think I know what you mean when you say push it a few stops. Maybe it\'s something related to ISO? What is your setting on the ISO mode? Most point and shoot digital cameras have rather small image sensor where if you shoot it in a low light environment, the picture could gets very noisy and grainy if you use the high ISO mode. If you use the low ISO mode, the noise and grain will be reduce nicely, but that requires a longer exposure time for the light to enter the camera\'s image sensor. Hence, meaning you have to hold the camera steady for few seconds before the picture is finally taken...I could be wrong though...
Bigger image sensor remedies this problem because the image sensor is big and are a lot better at capturing light than smaller image sensor, meaning it doesn\'t require longer exposure time to get a good picture in low light situation.
Most SLR digital camera uses big image sensor like the Canon Rebel, although not as big as a 35mm film camera, but its a lot bigger most point and shoot image sensor. Nikon is another good brand to recommend for digital SLR camera and can be competitive with Canon digital SLR camera.
