[Radiance-general] Photosphere

[Martin Moeck]

Greg and others,
 
I will validate Photosphere and thought about the following testing parameters:
 
matte saturated colored samples
matte Munsell gray cards
variation of f-stop from 2.8 to 8 (min and max on my digital camera)
incandescent vs. fluorescent vs. daylight (daylight is tough as it varies)
on-axis vs. 40 degrees off axis
colored and gray cards on black vs. white background
sample size around 4 X 4 cm^2 photographed at a distance of 5 meters or so
 
tested against spot luminance meter 1 degree
 
Any other suggestions?
