I'm just starting to get into exploring the settings on my Canon S30 camera,
but am noticing that changing the aperture setting doesn't seem to have as
much of an effect as images I see in magazines and on the net would suggest
it would. The difference between the maximum f8 and the minimum f2.8 seems
to be much less than I would expect from what I have seen and read. Is there
anything I could be doing wrong or any quirk of the camera to know about?

Thanks
Dee
