Having that psychokiller smile

I don't photograph well - either I gurn like an idiot, or else look so pyschopathic it frightens the horses. Yesterday an interviewer needed a photograph of me, but they were in London and I live in Scotland. So I sent them the nearest thing I've got to a headshot. Ten minutes later I got a request for a picture of me smiling, something less... scary. I took some snaps with my digital camera and sent off the most cheerful, optimistic picture I could extract from the bunch. Below is one of the images that didn't get chosen. You can see why, can't you?
