64

The strangest thing about this, is that I took about 5 shots in succession, each with a slower shutter speed than the last, while walking forward. This image at 1/6 of a second is the lowest shutter yet the sharpest of them all. Where it should be quite abstract.
What I find strange is the large swooping blur, yet the faces are very distinct. The entire frame is sharp yet blurry and the world is blended together in such an interesting way.
