Crystal photography using a Macro lens

As I’m experimenting with my new Macro lens and crystal photography.  I am trying to figure out how to better shoot crystals using a macro lens, which I am really enjoying! 

I have been cleaning some crystals in an Iron Out bath recently and thought I’d take some progress shots.  These are crystals dug earlier this year and some last year.  Here are some of the experiments.

These two both came out of the same area of the little seam I was in. Both had interesting secondary growth patterns! f11,1/100, iso400, 90mm

This one had small crystals growing in the overgrowth gap. Interesting etching as well. Needing a good depth of field for these macro shots. Manual focus, f11, 1/100, iso1250, 90mm.

This crystal has some interesting faces in the overgrowth. Trying to capture the point and the faces in focus, so needing a deep depth of field. f11, 1/00, iso1000, 90mm.

Amazonite. f11, 1/100, iso125, 90mm

This crystal has some neat little gemmy sidecars. f11, 1/100, iso1250, 90mm.

I love this side shot showing the color zoning in the crystal. Love the sawtooths at the top left! f20, 1/100, is0640, 90mm.

Was going for a shallow depth of field for this end crystal which shows the iron staining and multicolors this fluorite has to offer! f5.6, 1/100, iso100, 90mm

This is part of a much bigger fluorite crystal that disintegrated once I tried extracting it. But the apple green contrasting with violet is amazing! Background was the 12 inches of spring snow and the crystal was backlit by the morning sun. f3.2, 1/2000, iso100, -0.7 step, 90mm.

This is two of the three pieces I was able to salvage. They are still pretty stained with iron oxide, will continue giving a iron out bath. f9, 1/100, iso100, -.7step (oops), 90mm.
