Rekd, this was shot during the day in natural light, just lucked out on that background, it was a bunch of dark green trees that just didn't register on the exposure.
These shots weren't really all that difficult to take. The hard part is doing the trial and error of locating your feeders in just the right spot to get good lighting at certain times of the day, then just sitting still and waiting.
I've had limited success so far. Don't want to hijack, link below. I've been learning enough so I'm going to go get my own cat feeders, err, honeybird feeders and find a nice spot under an oak tree where I can sit and relax... :thumbup:
It's an fantastic photo of the humming bird, which are rarely available to watch. I like the background of the 2# image slightly greenish effect and the clarity of the photo is superb. Excellent job.
