Okay, I can't resist. Nice pics Donnyj. Like you guys, I have an ongoing informal "capture hums in flight" project. I just recently saw the most outrageous hum-in-flight pic I have ever seen! I have exchanged emails with the fella that took it, and have begun following his instructions. The first photo is my very best shot to date. Many times better than I have ever done before. The second shot is this fella's fantastic photograph!
My shot was taken at about 7:50 in the evening on the fourth of July. The essence of this deal is to stop action with flash. Our hums come around until about 8:15 or so. So the time of my shot was during their last evening feeding. There was still enough light that I could see the trees in the background, but the flash pretty much blacks out the background.
My shot was taken from about three feet away, at 1/60sec. shutter speed and f 3.5, which most cameras will do as a default flash setting. The only other secret to it, is to lock the focus on the feeder, which is I guess a little fancier thing to do than some cameras may be capable of. You can probably tell I'm into photography. It isn't a very fancy camera though, a newish Canon A620.
