How does the G10 exposure compensation knob actually work? Does it lighten & darken the exposure digitally, or does it adjust the aperature, or something else?
Thank you again,.....marc

I don't have a G10, but assuming that the exposure compensation is the same as on all other Canon cameras:
EC tells the camera to make a different exposure than it would normally select according to the metering mode and software.
Suppose you are in Av mode and select ISO 100 and f/4. The camera looks at the scene and selects 1/100 seconds.
If you then dial in +1 stop EC the camera will change the shutter speed to 1/50 and the resulting picture will be one stop brighter than it would have been at 1/100.
If you dial in -1 stop EC the camera will change the shutter speed to 1/200.
This is all for just one example condition. Every picture will vary for the actual light.
