The camera club was invited to do some macro photography at the Missouri Institute of Natural Science.  When I first heard about the trip, I knew I wanted to shine light through translucent objects just to see what it would look like.  With the exception of the picture of anthracite coal, all were photographed using this method.  All were surprising.  For example, seeing a rainbow in the calcite, or the deep hues of the fluorite and the other-worldly red of the sea urchin!
