Aperture problem with S30?

[dee_s...@hotmail.com]

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

The aperture number is an indication the ratio between the focal length
and the size of the effective opening of a lens.
A smaller aperture-number means larger lens opening. This also means
more light passing, shorter exposure times, less blur from moving of
camera or subject, but also a smaller range of sharpness from foreground
to background.
The effect of the latter is more noticeable for lenses with long focal
length. The old 4x6 cm camera's (with standard 100mm or so lenses) had a
very small sharpness range whilst digital cameras (with standard 12mm or
so lenses) give a much larger sharpness range from foreground to background.
Therefore the difference between 2.8 and 8 will not be very obvious with
digital cameras.
