Okay no progress here.

I have a carrara project open to render.  On the right I click the main camera.  So now I look under transform and see xyz across

Then down  I see:

Center
Hot Point
Orient
Rotation
scale
sizing
overall

Is there where I am supposed to be.  I have tried rendering and then going back and adding 0.06 each way but now am thinking of setting original to 0 and adding 0.03 each way.

Please advise which camera dial I should use.

Thank you.
