Here are two pictures taken with a D70s and the Nikkor 60mm at f8 (could be any camera).
One shows the "normal" DOF and the other an extremely larger DOF.
How was this done?
- set the camera on manual focus
- mount it on a tripod
- shoot several pictures, each picture with a small change in focal plane
- combine all the pictures into one with a special program e.g. CombineZ (free!)
On a slow computer it is now coffee or Belgian beer time

Does this work the same as stitching programs for panoramas? Or can you also increase DOF this way if you want to have a horizontal environment sharp front to back and a vertical subject sharp top to bottom at the same time?

It is very useful if you want to increase DOF locally, using masks. Looks pretty weird though. For general increases of DOF, if one has the camera mounted on a tripod anyway, using a very small f-stop is just as effective. Photoshop is a wonderful thing; decreasing DOF (masks and gaussian blur) or adding motion blur can be very succesful manipulations.
I would say, Peter, that using local DOF enhancement in various passes can put your increased DOF anywhere in the picture you want.

Jaap,
Pay attention with very small apertures. At a certain point they start to act as a pinhole camera, decreasing the overall sharpness.
Anyway the DOF example I posted would be difficult to obtain just playing with the aperture.
This technique can be combined with panorama's.
An example :
A macro with large DOF and an enormous resolution.
For examples: see the forums of PTAssembler.

This is a common technique in micrography and sometimes used in macro photography. Most member in the site below use similar software with microscopes.
