I think it's a matter of preference. I usually start with a medium focal length of 80 - 110. Then I do my posing, then I may try adjusting FL a bit to see the effect. It really has far less difference in Poser than it does in the real world. In photography, the primary criteria that go into deciding on FL are Depth of Field and amount of light available (there is zero effect in this regard in Poser). The compression effect is another important reason for choosing a specific FL, and is the only one pertinent to Poser. One caveat: the closer the camera is to the subject (and this is true in Poser, as well), the more pronounced the compression or expansion effect of the focal length. If you're doing whole body shots, it will take more of an adjustment to see the effects a focal length change has than if you're doing a closeup headshot. -sk
