re.your #328 and the comment on not doing OM 3-Ds, I had intended to mention this long ago but it slipped me. They obviously have a way to do OM 3-ds if they want.
All they have to do is take an image at a particular stage position, say 6134, and then rotate the stage to, say position 6160, and take another image. The two images should show a 3D effect for at least the bigger particles.
That shouldn't be too difficult.
