A recent topic reminded me of something I noticed once when I made a video of myself shooting a bow I made. When I froze the video just after release, I could see the entire bend of both limbs and although I find it extremely hard to visualize tiller, it was extremely apparent to me from that view. I don't have a nice enough camera but I think that you could do the same thing if instead, you set up your camera far enough away to see the entire bow, set your exposure time for 3 or 4 seconds and bent the bow within the exposure time. Do people do this?
