I was watching Doctor Who Confidential on Saturday, and the effects people seemed to be recording lightprobe images. Just holding large reflective balls in front of the camera. Look carefully at the images which come with Poser, and you can sometimes see the phorographer dead-centre. Such simple lightprobes will have a gap in the coverage mayching the area of the scene hidden by the sphere, so if you were creating one in Poser I suppose you'd want to get the tight framing by adjusting the camera focal length, rather than moving the camera closer. That sort of fake lightprobe might be useful, but you need a full 360-degree set. And that's what it's supposed to replace. I've seen a description of a low-res lightprobe, using roughly-blocked light and shade.
