I recently posted a thread about The Photographer's Ephemeris and what a useful product it is. http://www.pnwphotos.com/forum/showthread.php?t=980
Tonight I decided to do a field test of the product. We had an incredible sunset last night, and the haze in the air tonight made it appear that there would be another nice one.
So, I decided to fire up the Ephemeris and see how it did...
My goal was a sunset shot on Puget Sound. I wanted to get as much water as possible in the shot.
