also change the lighting - Kodak has some nice old booklets from the 1970's or earlier on how to do this sort of thing (if you can find them)

you can add an aux. lens or flip a lens backwards for closeup work also - or buy an old micro lens

Lighting:

you generally want 2 lights, set at 45 deg to the subject (crossed) on each side of the camera

then put an old cut up milk jug in front of each one to diffuse the lighting
