I've been meaning to mention this for a long time, but I am a huge fan of Vincent Gallegos' blog and photography, and essentially a while back I realized that Gallegos is easily the best "event photographer" in the DMV.

If Gallegos is there for your opening, taking pics and mixing in, then you know you've got a kewl opening going on.
Check him out here and be prepared to see what one day will be a historical record of the DMV visual art scene and then more.
