People must've wondered what in the world I was doing, for the car was parked on one side of the road with the four-way flashers on, and I was standing on the other side of the road. Another dog walker gave me a very wide berth.
Anyway, I got set up, and hoping that traffic wouldn't be heavy (it wasn't), I took a few shots. The first one came out the best.
But then as I was going through the photos this morning, I noticed something:
That green ball wasn't there in the first photo.
And it seemed to move around the subsequent ones.
Could it be just a Newton's Ring, or is it "something else?"
(Correction: Could it be just lens flare, or is it "something else?" See comment section for explanation.)
