Dear list members,
I use hemi-spherical HDR images to compute a vertical irradiance value (W/m^2) for each color channel.
If I wish to compare/calibrate these numbers to a reading from a light meter (giving illuminance in Lux) how do I go about converting the three (RGB) irradiances to illuminance?
