The ones that get away

I did a week long shoot at the Toronto International Film Festival a few years ago and I got a lot of really great portraits but what I keep coming back to is this board of polaroids that I sent to the lab as color reference and that has been taped up in my office ever since.  There's something about each of these frames of these actors that was captured on polaroid but not on the film.  I got great shots of them on film, but something is different in these polaroids.  I'm not sure what exactly it is that sets these images apart from the "official" shoot.  Maybe it was the fact that we all knew we were shooting polaroids and that put the subject at ease and that's what you're seeing?  I know a lot of photographers can relate to having something on a polaroid that you don't have on film.  You always tell yourself you don't want that to happen.  But it does. This doesn't really relate to shooting digitally because when you're shooting digital your "polaroids" are the same as your finals (they're files, after all).
