My girlfriend has a Canon S3 IS digital camera with Super-Macro, so I stole it and tried taking a few pics of some smallish minerals I have in my collection. Sweetwater Missouri calcites with chalcopyrite and galena. Largest calcite measures 1/2". Overall: 2 7/8" x 2 9/16". Pyrite after marcasite (??) with hematite, from Baffin Bay, Canada. The large crystal on the upper right side is 1/2" long and 3/8" wide. Overall: 2 7/8" x 2".

Cool specimens!
Good use of lighting and depth of field. Have you tried flipping the bottom one? It "feels" upside down.

Thanks! I had the pyrite piece propped up a bit for the pic, that's why the angle looks weird. I lit it from under the camera with a fluorescent tube for better differentiation on the facets of the crystals.
I read up on macro photography and made a small flash diffuser to play with for more pics. I have to fold up some boxes for a better base to start with too. This camera will take perfectly focused pics with the specimen touching the lens! Now where are those batteries...

Chad: Thanks for the links on focus stacking! That will solve one of the biggest problems with macro: limited depth of field. I'd recommend a focusing rail because changing focus also changes magnification; maybe the software corrects for that.

Here are a few more. Analcime crystals from King's Valley, Oregon. Cuprite on dolomite from Michigan somewhere. Quartz, pyrite, chalcopyrite and hematite from Peru. Topaz from Mexico. Specimen is under 1". I never noticed the tiny green crystals before. I wonder what they are?

Such a world beyond my comprehension, these micro-mounts. It's so easy to focus on size, size, size, that I usually go right past the little wonders.
