great!

Now we do understand the Dolly cam a bit better, can somerun run similar tests for the Revolving cam? 

That's a good idea! I gave up trying to work out an exact value for the inherent offset value for orbiting cams ( http://www.renderosity.com/mod/forumpro/?thread_id=2880985  - roughly 1.2 Poser Units along the +Z axis was as far as I got.) But using the same test as the dolly cam (i.e. a 90 degree FOV, the diagonal stripes, and butting adjacent renders together) and the assumption of 1 inch sensor size, then a bit of trial and error with the +Z offset might be worth a try...

I may give it a go sometime over the next week (and I'll be reading your stuff on the revolving cams too!  :)  )

The 3Dcheapskate (also available in DAZ and HiveWire3D flavours) occasionally posts sensible stuff. Usually by accident.
And it usually uses Poser 11, with units set to inches. Except when it's using Poser 6 or PP2014, or when its units are set to PNU.
