Chad and Megan

Chad & Megan
Chad and Megan are two of my biggest supporters.  They have a houseful of my images, almost literally.

I recently had problems with my old TV.  The power supply burned out and I had to replace it.  I bought a new one and was on my way to pick it up.  I stopped by to see them on my way.  They had a TV that they wanted to give me.  It is several years old but lightly used.

New TV
I had been having trouble seeing and hearing my old TV but this one has fixed all that.  I am most grateful for their generosity.

Thanks, Chad, Megan, Lucas and Loudon.

Obsidian Recap with Video

Obsidian
I consider this the best capture that I made of this side.  You can reduce the strength of a flash with settings on the master unit or you can move the flash further from the subject.

I am finding that the way for me to summarize my macro shots of a rock is to shoot video of it.

Obsidian Video
This video uses an LED light which casts a bit of a harsh glare even with its diffuser in place.  It does light it sufficiently for us to see the obsidian surface features in their juxtaposition to one another.

The sound is from Gorman Nature Center.  As the weather warms, the birds vociferate their joy.  Watch the Obsidian Video.  It is at the bottom of the page.

Obsidian

Obsidian
Volcano glass is formed by lava which cools quickly.  It contains a lot of silica.  I find that I enjoy trying to show it in the most informative light.  I am using flash instead of incandescent lights.  It is not as easy to set up the lights with flash.  I must anticipate what the light will do.  Digital makes this easier because I can look at the camera's LED monitor and learn what the light did immediately rather than wait for the film to be processed.  

Obsidian fractures to sharp edges.  It, among other materials, is still used on surgical scalpel blades.  Obsidian is metastable on the Earth's surface.  It breaks down in the presence of water.  None has been found older than 150 million years because of this.  It breaks down to Perlite, which is used as a soil amendment because of its lack of density.

Obsidian
This piece is thin, having two sides.  I found it interesting to try to show the surface features with the light.  I had to use FEC, flash exposure compensation, of -2 because my camera meter and yours tries to make everything gray.  I had to do this to get it black.  The features on the second side required me to put another light near the camera.

setup
The "master flash" is off.  It only functions to control the others.  I had to move the one near to camera to get the right angle.

setup closeup
I used a Stofen diffuser on that flash.  I placed the gray mat behind it so that you could see it in this shot.  It was not there when I captured the image of the Obsidian.

Bud Consolo, Volunteer

Bud Consolo, Volunteer
I had the privilege of meeting Bud the other day in the Visitor's Center.  Bud was very interested in talking about his children and grandchildren.  I was unsure about his wife, but later I learned that he has a wife.  I was sad to hear that Bud and his wife are moving to Cleveland to be near their oldest son.  

Bud raised his family visiting parks and camping.  This taught his children to love the outdoors.  The only one who does not work outdoors is the son in Cleveland who is a lawyer.  The two daughters work for the National Park Service, one at Yellowstone and one in Maine.

Bud, thanks for all you do at Gorman.
