Mark, could you expand on the technique? I think you are saying a flat face measurement of the source illumination is logarithmically averaged with a flat face measurement with the flat face pointed at the subject,
a single hemispherical domed measurement with the dome pointed at the subject (opposite of the typical incident measurement with the dome pointed back at the camera). Do I understand you correctly?

Oops, fixed.

Thanks for the proof read!

One reading pointed directly to the source light, one directly toward the camera, then logarithmic average.
