Free Workshops Teach Students Basics of Photography

It must have looked a little strange to passers-by on the boardwalk as Steve Wood knelt to take a photo of a small, plastic toy grizzly bear and cub perched on a bench in front of Old Faithful geyser. But it was Jeremy Sullivan's way of introducing his photography students to the concept of depth of field -- having objects close and far away in focus at the same time. "The thing that's fun for us is these folks are on vacation so everyone is in a good mood, and we're in a beautiful place," Sullivan said.
