Goodnight Mr. Sun [C_079730-2tc+92]
Not as interesting as I had hoped. I endeavored to capture the sun setting behind the Point Bonita Lighthouse. Calculating a sun alignment is quite a lot easier than a moon alignment, but not without challenges. I had never been down to the requisite beach so didn't realize that only the upper portion of the two structures on the spit of rock were visible. It's still gratifying, however, when the calculation works. Unfortunately I left in a hurry as I went to help a friend by bring him some gear for his photoshoot and left my solar filter behind. As luck would have it, the weather was unusually clear (for San Francisco), and there was very little "atmospheric extinction" (which translated means the sun was still extremely bright even though it was less than 1 degree above the horizon).
This isn't a single shot. It is a shot with the sun at very high speed (about 1/4000 of a second) and a longer exposure taken just after the sun had set. The focal length was not changed so the sun is indeed actual size relative to the objects in the view.
If you'd like to calculate when the sun or moon will be aligned with your favorite landmark, you can join me on one of my Catching the Moon webinars.
