Experimenting with new lens

I bought a Nikon AF-S Micro Nikkor 105mm2.8G ED VR lens to use for photographing my larger mineral specimens. As I have not completed the setup for that, I gave it a try outside today.

The flat ends of the crystals would be considered the top or bottom. This is the c face. The three crystal axes in the orthorhombic system are at r...

Charles,

I was over your way a few weeks ago to visit the mineral show there. As I recall, we met last November at the Kitsap Mineral and Gem Show. I was the guy with scope, camera, computer, and digital projector.

Thanks for the kind comments. The lighting is done with a 9 lamp LED ring light which is diffused and two 19 lamp LED spots which I position to the best effect. I may or may not use a diffuser on the spots. Exposures typically run from 1/3 second to 1/20 second depending on subject and magnification...

Albite

I have been looking on this site for several months. Having just registered, this is my first post. This is an albite crystal from the Poudrette Quarry, Mont Saint-Hilaire, Rouville County, Quebec, Canada. This is one of my favorite mineral localities due to its complex mineralogy. The photo was tak...
