I have shot endless hummingbird photos in the backyard at home. There was one shot that eluded me for a while. At a certain time of day, if a hummingbird is at the feeder, its shadow will fall on the post on the corner of our deck. I have seen it a few times when I didn’t have a camera handy and have had a camera when none came or the light moved around too quickly. However, I did finally get the combination I was after. I like the hint of the hummingbird without the actual bird in shot that it delivers.
