One of the harder parts when working with a model in a studio scenario has got to be the posting of the head. The problem that you run into here is twofold. First – its really hard to give someone direction as to where they should turn when they are opposite from you and in a different position. Want a good example of that? Hand someone a piece of paper, and without doing it for them, tell them instructions on how to make a paper airplane (These are the kinds of things I learned in school when I became a teacher).
The second is more id-driven. We don’t want to look like idiots. We KNOW what kind of look we want another person to give to us, but we don’t want to put ourselves in the position of looking foolish. In our ‘photographer’ heads, it’s bad enough that you are being subjected to making a good image because you TOTALLY dont think of yourself as a good photographer, but to put yourself out there even further by looking like a moron? Absolutely NOT! This usually leaves us with a bunch of “Turn right.. no.. the other right.. no.. tilt up.. no i mean turn up.. I mean open your mouth.. um.. ” And lots of valuable time is lost.
Or, you can pinch their nose.
