The diagram has markings showing distance values in meters
Dof from via to
Lens tilt is degrees
Lens to sensor distance is % of focal length
Focal length is mm
Aperture is f/
Camera tilt is degrees
rise/fall % (100% is full rise)
CoC is mm
use 0.2/m where m is magnification if you want 'noseable' prints. 0.05 is an excellent choice, 0.1 is OK.
