Photographing big white birds on a sunny day on dark dark water is an exposure nightmare, lol. Here's one where the whites weren't COMPLETELY blown out on momma. I like the pose, it's like she's trying to teach them proper posture but the little guy in the back is the only one getting it.
Then there's this one ... I just like it because of the grouping of the little fluffballs.
And then in this one I think the exposure on the cygnets was pretty good, but of course now momma's tail is blown out. Oh well, I'll get there eventually.
