Hello Nathan, this is jimcseke.
I am not sure if you remember me, but a while back you and I had a discussion in the Photosynth lounge about edit images for an improved point cloud.
I have been away from the actual synthing for about 2 months now, and since you and I seemed to share an interest in accuracy, density, and editability of the point cloud, I though you might find the discussion I just started interesting and useful.
try to read it in it's entirety as most of what is written is relevant.
Have a great weekend,
