So far, I've gotten through all four stages of the test with mixed results (I'll post them after I hear back from a few people).

Ockham, I was thinking about how to make this idea more intuitive. Instead of the target figure's scale, would it be possible to use (f-stop value = x rotation(in degrees)/10)? That would give us a value of 0 to 36.0 for f-stop (disregarding Poser's 6 sig digits) and we'd be able to "fiddle" the value with a linear dial twist.

I've come up with a few problems involved with the "scaled f-stop" idea. Mainly, getting a high f-stop value might require creating scene occlusion. Rotating the sphere in x, however seems more natural. stewer: Does Poser actually use -180 to 180 degree references? If so, linking to rotational value would mean including a line that flopped negative rot values to a positive integer, right? If that's necessary, I can post C++ code to do so, and you Python gods can just convert it if you like. =D
