Photogenic

I'm sure you have heard someone whisper, jealously, "she's just so photogenic". Some of us even hide from the camera because we simply think we aren't photogenic. But we've also probably heard, or come to the realization, that's it's not just that we aren't photogenic. There is something behind being photogenic - beauty. But I think I may have taken it too far - some people simply do look better on film than they do in real life, and presumably the reverse. I realized this when I was looking at some pictures of someone I know. She is a good looking girl, but almost always looks terrific in photos. Something about her shape makes her appear even more attractive in pictures. I suppose this is why people often say movie stars don't look as good in person. Two dimensions just don't capture everything in the three dimensional. But still, the "I'm just not photogenic" excuse gets old after a while.
But perhaps most importantly, there should be a noun for photogenic, like "photogenocity".
