Stevie Wonder -- For Once in My Life ... I'm a TMZ Photog!

Stevie Wonder can't see, but Wednesday he shot video for us and frankly it's as good as most of our clips.

Our photog Adam armed the singer with his rusty, trusty camera outside Letterman's show, and with a few tips Stevie was a great pupil ... his shooting was dead on, even picking people out of the crowd.

It's been a dream of Stevie's for several years ... to join forces with our camera guys.
