This is a German soldier with a panzerschreck.  The scan is not retouched.  I have focused the original camera, and upgraded  to focusable lasers.  I think I'm at the limit of what can be done without upgrading to the 8MP Camera Module v2.

These were scanned in 5MP still mode, with noise removal disabled (I figured I'd rather preserve details, and remove errant points in Meshlab). I did use the talcum powder technique to knock down the gloss, and make the black bumpers, top, and tires visible. 

I'm quite pleased with the results so far.  The Atlas3D seems to have picked up the details nicely.  I'm continuing to refine settings, lighting, etc.

I should have the new software updated wrapped up soon.  Once I do, I will switch gears and see what we can do about scanning smaller models at higher detail.

Any movement on this front Uriah?

Excellent!  I wasn't looking down far enough.

Thanks Uriah!
