Why would you use a large aperture to increase depth of field??? A
large aperture will decrease depth of field. Did you perhaps mean a
large focal ratio?

This may help explain. Here is a series of photos with different focal points
and the resulting image stack. With something as small as an N-scale engine,
you can't get the whole thing in focus and still have it large in the frame.

That's an interesting method, particularly for objects that will not move
from one photo to the mext. For flowers, however, movement of the subject is
inevitable. For subjects such as that, a telephoto lens with a large aperture
is more practical.
