When to use a very small aperture

[johnpower@verobeachlaw.com]

My camera will go to 22 but I am not sure when one would want to use
that small an aperture. It seems like most people range between 2.8
and 8.0. When would you use a 22, 16 or another high number?

When you have enough light to allow a fast enough shutter speed and you want
a deep depth-of-field.

10D, but I don't have to go to f22 to get good DOF.

Obviously you haven't done much closeup/macro photography. You've gotta
struggle for every millimiter of DOF then. Especially at longer focal lengths.
