These images combined the old and the new – my\u00a08 year old\u00a0100-400mm zoom lens (with attached\u00a01.4 teleconverter)\u00a0and the new 7D Mark II camera. I thought the combination performed\u00a0pretty well.<\/p>\n

I photographed this Northern Harrier a month ago as it was hunting the Antelope Island causeway.\u00a0These two shots are consecutive images in a burst with the Great Salt Lake in the background, including horizontal bands of mud in the very shallow water. I found those mud bands useful in gauging something I’ve been mildly curious about\u00a0– how much elevation is lost,\u00a0if any, during the wing upbeat?\u00a0(yes, I do wonder about trivial things like that…).<\/p>\n

The two images were taken 1\/10 second apart and the wings are in the down position in the first image and the up position in the second so the two images cover a single upbeat. The lowest band of mud behind the bird is an indicator of elevation since my elevation didn’t change. By comparing the position of the harrier relative to the mud band in the two\u00a0photos…<\/p>\n

it appears that no net elevation was lost.\u00a0 Only the angle of attack changed, which tipped the head\u00a0lower and the tail higher (first image to second image)\u00a0but the center of gravity seemed to remain in the same position relative to the horizontal mud band. With most backgrounds this is something that would be difficult or impossible to judge.<\/p>\n

But why do I care about stuff like this?\u00a0That bit of knowledge\u00a0likely has no practical application to bird photography so I guess it’s nothing more than “pure science” for me.<\/p>\n

And curiosity.<\/p>\n
