I was just curious if shooting indoors would counter depth of field problem when using digital instead of film.

To what problem are you referring? The depth of field is only changed indoors if the iris is opened because there is low light available. Most digital cameras have a very broad/wide depth of field in almost all conditions. It is possible to use neutral density filters outdoors to be able to open the iris more to get a more shallow depth of field (background out of focus), but it is not as apparent as in a 35mm film camera.

To have the least depth of field you need to open the iris wide open. This is easier indoors because there is less light. Outdoors you can use ND filters to reduce the light.

Still more difficult, but not because of being digital, but mostly because of the small size of most digital cameras sensors, 1/4" 3/8" etc.
