Chris T:

I think that I'd like a camera that would automatically take a series of photos with different foci so they can be combined to make a picture with tremendous depth of focus.

When taking macrophotos, sometimes manipulation of f-stop does not produce sufficient depth of focus. What are some ways (preferably easy and inexpensive) to improve this aspect of photography in close ups of model dioramas? I have heard of something called "stacking".
