Just remember that the image from a mirror is reflected at the same angle as the original object, but in the opposite direction.

So if your figure is standing directly in front of a mirror which is at 90 degrees to him/her (and upright), then the camera would have to be directly behind the figure to see the mirror-image (which probably wouldn.t work, 'cos the figure itself would get in the way of the reflection).

So shift the figure slightly to one side, and shift the cam the same amount in the opposite direction. (Or, equivalently, shift the mirror slightly to one side and shift the cam twice that amount in the same direction.)

It still coms down to "suck-it-and-see", but if you understand the physics, it'll help.

One way to think of it is like playing snooker/pool/billiards.
The cushion is the mirror.
The ball is the figure.
The cue is set at the angle which the ball will hit the cushion.
Position the cam as if it were something you want the ball to hit, but looking at the point where the ball will hit the cushion.... Imagine it from a top-down view (and in Poser, use the top-view cam to work out the angles..)

Cheers,
