Photographing Pentagonite


Photographing Pentagonite
The field of view in this one is 7.74mm.  The cluster of crystals is about 5mm wide.  When I removed them from the capsule.  I wondered how to mount them.  I read about the mineral and found that it was not very hard, 3 - 4, and brittle.  I was afaid to handle it for fear of breaking it.  I'm fairly shaky this days but I succeeded.

Pentagonite
I removed it from the capsule and finally decided to mount it on a piece of glossy photographic paper.  I placed a drop of super glue on the paper and set the cluster in the middle of it.  

Mounting Pentagonite
I could then crease the paper and use it attached to the alligator clip.

Mounting Pentagonite
I wanted frame filling but not frame bursting.  I had  to look for a less powerful combination of lenses.  The one at the top was the outcome of less power but it also cut of the top of the central cyrstal.  I set it on a canvas that extended beyond the limits of the edge and drew the top of that crystal.  The results are shown in the image at the top.  With the less powerful configuration, Sigma 105 mounted on 136mm of extention I was able to achieve this one.

Pentagonite
 I consider it the most successful.  The superglue did show a little at the bottom and I cleaned it up.  I wanted it to show so that the image would be grounded.
