Texas Capitol Building from UT Campus, May 17, 2013

I was going to do a few shots of the graduation of the University of Texas, Austin, McCombs School of Business, but after review I felt they were too personal or not quite interesting enough.

After the graduation we began to walk back to our vehicle.  It was dusk and we were just below the Gregory Gymnasium.  My older son, Aaron, pointed out the glow of the Capitol Building dome from our vantage point on the sidewalk.

I had the camera cranked up to 6400 ISO, the fastest it will go in normal mode.  I had pushed the zoom lens out to its maximum length of 400 mm.  At 400 mm the aperture opens only to f/5.6.  And it was hand held.  The camera metered at 1/40th of a second.  I took two horizontal frames and this single vertical.

For those of you who are wondering why this is special here is the scoop.  If you shoot hand held the exposure time should be no slower than the reciprocal of the length of the lens.  That means a 400 mm should be shot at 1/400th of a second, a very small amount of time.  At 1/40th of a second the shutter was open a lot longer which means there is a lot more chance of camera shake.  The lens and its internal stabilization allowed 3 1/3 stops more exposure.  That is amazing.

My opinion is this is pretty good, but not great, about a 6 or a 7.  Because it was at a super telephoto length the lens blurred out the foreground trees.  On the other hand the color is great and the subject appears tack sharp.
