I have a Gossen Luna Pro SBC (I love that meter), and a Sekonic L-398. They both agree 100% when the light source is white, but when the light source is the blue sky, the Selenium cell (Sekonic) reads hot by as much as a stop (or conversely the SBC reads low). Which cell most closely represents the way Panchromatic film handles its values? What spectral response more closely resembles the sensitivity of the human eye. I understand (from the Ilford Photography Manual) that the Silicon diode in the SBC is more sensitive to IR, but it has a filter in place to make the response closer to that of the human eye.
Thanks,
