IIRC, Stevie Wonder isn’t 100% blind. He is capable of the vague discernment of light and dark and extremely vague shapes. But he is, functionally blind, by any practical definition.

So if someone was approaching him, especially if a group of friends surrounding him might have whispered into his ear, “hey, Michael’s walking up to you!“ He might’ve smiled in time for one of the dozens upon dozens of paparazzi surrounding them both to snap an opportunely-timed photo.

One must consider context

Wide angle lens distortion. The camera is probably a lot closer to the whole scene than it appears, and because of that, it’s closest to whether of in the middle foreground of the frame.
