Wouldn't it be cool to see photographs projected on the sides of iconic buildings and skyscrapers in downtown Boston?

That's the dream of some local photographers and visual artists who are working to put together a festival next fall that would use buildings and huge projectors to highlight some of the best local photography.

The Bedford Center for the Arts is starting a four-week digital photography series this week, featuring three professional photographers who know what they're talking about, and one real duffer.

Connie Drapeau Kennedy, a RAW regular, sent us an e-mail about the Second Annual Worldwide Photo Walk being held this Saturday, July 18, in hundreds of places around the globe. She's hosting a walk in Marshfield, but there are 13 other walks in Massachusetts alone.

The walks are social events where photographers get together, usually in a downtown area or trendy section of town, to walk around, shoot photos, and generally have fun with other photographers. They last about two hours, and Connie says they're fun, free and it doesn't matter whether you're a beginner, serious amateur, or professional. All you have to do is sign up, using the event's web site, then show up.
