Through trial and error, I have discovered that the VrayPhysicalCamera with Vray Sun/Sky with intensity of 1.0 at at these settings: f-stop 8, shutter speed 200, ISO 100, vignetting disabled, Color mapping Linear defaults (dark 1, bright 1) is almost identical to the Max camera with Color mapping Linear of dark 0.031, bright 0.031 (using 1.5 SP 1 w/ Max 2008 ).
Is there a (simple) formula or chart somewhere that can take the guesswork out of this? I need to have diffent exposures (interior vs. exterior) with Max cameras that match Vray physical cameras. I do not want to adjust the intensity of the sun, because it just feels wrong.
If I wasn't mathematically challenged, maybe I could write a formula...
