Photo of the Day - 7/25/2014

I wish I had thought of posting this one several days ago to better coincide with the 45th Anniversary of the Apollo 11 landing.

There re a couple of things that make this image more interesting than it first appears. 

First, it is a color shot.  I tried changing it to black and white, but didn't think it looked as good.

Second, it was taken hand-held (as opposed to using a tripod) with a manually set exposure.  The latter part was easy to figure if you know two things.  The first is that all the light of the moon is reflected sunlight, so set the exposure accordingly.  Second, the way to figure this out is using the old "Sunny 16" rule, which says that the proper exposure on a sunny day is f16 at 1/focal length of your lens.  Since I was using a 400mm lens (which adjusts to 640mm due to the nature of my digital camera), this works out to f16 at approx. 1/600 of a second (which is more than fast enough to hand hold).  However, because the sun is really bright, possibly underexpose a bit by changing this to1/800 of a second.

Sorry if all that is a bit technical, but keep it in mind next time you want to shoot the moon.
