Resist. or get dirty.
This shot, with its imperfect focus, is not .. perfect. But see that wildly distorted background? I was hanging out the window of a 4WD while it was bouncing and sliding down a gully on a washed out mud track. It happened that the butterfly was on the wing beside us, and I couldn’t resist going for a shot.
Have you been four-wheel driving in the mud and wet… with the window down?
Not even if a butterfly keeps pace and you have an irresistible urge to shoot it on the fly.
