A friend recently posted this to my timeline, suggesting that it was an unedited photo. That by the time the shutter opened to the bottom half (right side of this photo) of the sensor, the child had opened his eyes. I know this sort of camera trickery isn't necessarily useful, but it makes me curious. Is he blowing smoke or is something like this actually possible? If so, I'd love hear your suggestions as to what shutter speed range youd suggest using to try replicating something like this. So far I've tried speeds in the 1/250 - 1/500 range with no luck.
