I have new-found respect for the patience of nature photographers. I took this photo standing in the hot sun at Taylor Bray Farm in Yarmouth. The swallows were flying at the speed of light in and out of the lower level of this old barn, and I thought it would be easy to capture a shot of them as they whizzed back and forth to feed their babies. After about 10 minutes and 30 or so shots I gave up, hot, tired, and disappointed. But when I got home and looked through the pictures, I realized I'd gotten one good photo after all.
Patience is a virtue. Have it if you can. I'm working on it.
