Deformed Rock

Deformed Rock

I find these rocks beautiful.  They were included in a bucket I bought at the lithic and lapidary show a year ago last summer.  I am still going through them as I have time.

How could these shapes come about?  I have learned from watching "How the Earth was Made" that there are forces and heat as well as sedimentation that brings these about.  Hypothetically speaking, the lines could have been laid down as sediment.  Later that rock could have been subjected to heat and pressure, probably deep in the earth's crust.  That could have formed it into these intricate shapes.

Please note the skin of crystals on top.  We will see more of it later on.  

Crystals on Deformed Rock

This is a closeup view of the skin of crystals from the previous shot.  As I understand, the crystals form as the rock cools.  It the rock cools quickly near or at the surface, the crystals are small.  If it cools slowly under pressure, further down, the crystals grow larger.  This skin of crystals may have formed as a separate process at a later time than the deformation we saw first.

The crystals appear to be clear.  The question becomes, "What could they be?"  Diamonds are formed at great depth and under great heat and pressure.  They then come to the surface through kimberlite pipes.  I have no idea whether they are diamonds.  I can tell you that if they are, they are very, very small.

Bird Skull

Skull and Spine

This partial skeleton was given to me by someone.  I don't know if it is illegal for me to have it.  I have been told that at Gorman we must turn in dead birds and even bird feathers.  I have had it for several years and just got around to photographing it.  I am told that it came from the shores of Lake Erie.

Skull and Spine

It was most interesting to me as I photographed it, to note how is was made.

Eye Socket

I wondered if I could figure out what kind of bird but I had no success.  Any ideas?

Spine

You may note that there is some connective tissue still present.

Eulalia Grass II

Eulalia Grass

My daughter recently remarked that she would like a print of eulalia grass for her house.  Her comment motivated me to work our one clump of the plant while it still remains with seed on it.  I captured this one the other morning during high wind.  Needless to say, it was difficult to get it sharp, especially using a 500mm lens.  I did like the blurred back ground it provided.

The next morning I arrived earlier and worked it more while the sun was in the process of clearing the trees behind.  The light is filtered through the trees on this one.  

Eulalia Grass

This capture has a slight flair in it.  I have since edited it out in the master file.  The wind was only very slight to none.  I wanted as little DOF as I could tolerate and keep the subject sharp using a 70mm lens.  I wanted the background to be as soft as possible.  I found that f/8 was the least DOF I could use.  It left the background sharper than I had hoped but the shadows helped set off the grass heads to my satisfaction.

Eulalia Grass

I decided to work the scene at least until the sun cleared the trees.  It gave more highlights on the grass head.  At the time, I thought that might be ideal.  Since, I have gravitated more toward the softer light filtered by the trees.  What do you think?
