I am no expert by any stretch but one tip I can offer is use a stable tripod and a shutter delay. That way when the shutter snaps there is absolutely no lens movement. If you are holding the camera you will move it. I guarantee it.
I have also learned that most point and shoot cameras (not all but most) cannot focus well up real close, or with the digital telephoto feature. The best camera is the kind that will let you overide the autofocus and do it manually.
Lighting is the number one consideration when taking good pictures and since I am too lazy and too cheap to make or buy what is needed, I usually take the pictures outdoors on a gray overcast day. No direct sunshine.
Jerry is making a set of one piece ivories for a 44 SAA of mine as well as fitting a 44-40 cylinder. I am lucky to live only about 15 miles from himso there's no shipping issues.Last time I was over there he had two whole tusks sitting on a workbench.
