Hi John,

I have done a quick comparison (probably 7 years ago or so) as I was working on 
validating Photosphere. It was not a comprehensive comparison but I remember 
that Photsophere results were more reliable when compared to measurements with 
Minolta luminance meter, especially with higher luminance values.

Best,
Mehlika

Anyone aware of any comparisons between Photolux and Photosphere -- mainly for 
accuracy and calibration?
