Depends on how the renderer removes objects not visible in the scene. If Poser considers the "parts" of Victoria as separate objects that can be removed because they are not within the view frustrum of the camera, then they will be removed early enough not to effect the rendering time much. Also, most renderers (hopefully all) do what is called polygon clipping at the view frustrum. Here, polygons that are completely outside the camera's view are removed from consideration. Still, there are times when this must occur later in the calculations - when shadows or reflections must be calculated - can't remove objects and polygons before doing these. If you want to do a head shot and definitely remove unnecessary geometry for quicker render calculations, you should make those areas hidden or not used in the render. BYS
