Superb work. Digital technology has brought us gear that can finally make this kind of capture possible, but it still takes deft skill to pull off this kind of performance. Congrats on beautifully technical art.
Could you please post a list of your gear and settings? Though I don't think it will be anytime soon that anyone else will be able to reproduce your success!
I have seen many many butterfly photographs, but, I never see them of the butterfly in flight. Here are a few of mine. A butterfly is so much more expressive when it is aloft, don't you think?
Yes, I agree, it is much better to get a good shot of a flutterby in flight (I like that!), but it takes a lot more effort, skill, and patience. I spent about an hour photographing some moths (I think they're moths, not butterflies), got a bunch of good shots with them on a plant, but only a couple of good shots of them flying.
