I used to have a terrible habit of blinking just as the person took the photo. I remember loads of facebook pictures where it looked like I was asleep because I'd blinked at just the wrong moment, or because my eyes were reacting to the camera flash. To counteract this I now raise my eyebrows ever so slightly. As weird as it sounds, it seems to do the trick. I think the other important thing when having your photo taken is to just try to be natural. If you don't want to smile, don't. If you want to grin like the cheshire cat, do it. Whatever you feel comfortable doing.
