Here's a conundrum: does an upside-down smile shutter become a frown shutter?

Saturday afternoon experiment, readers! A friend of mine brought up an interesting question last night. If you turn a camera with a “smile shutter” upside-down, will it only take pictures when everyone in the picture is frowning? And if so, have we just stumbled on a new photography technique for emo kids?

It’s a serious question, and I wish I had a smile shutter camera with which to answer it. But I tend to avoid those as if they’re covered in poison ivy. My theory is that it won’t work because the face recognition won’t work — I think the pattern they use to recognize faces won’t function when all the faces are upside-down. But maybe you could make it work somehow.

If your camera has a smile shutter, give it a shot and report back.
