Dear list,
I plan to build several radiance models of Alzheimer care facilities in
preparation for a field study examining daylight exposures and cognitive /
health outcomes in partnership with a colleague in health sciences.
The radiance work is intended to supplement the data collected from
physical sensors to provide greater insight into 24-hour patters of light /
dark.
I would like to measure the surface optical properties (color,
reflectance) of the walls / ceilings and floors etc.
I am aware of two devices that have been used to do this.
1) The first is the X-rite Colormunki (actual name of product) that Michael
Donn was using while visiting LBNL.
The second is the Minolta CM-2002 Spectrophotometer used by Mehlika Inanici.
If anyone has experience with this task who can provide some comments on
their approach it would be appreciated. (Michael and Mehlika, i will likely
contact you directly!).
Best,
-Kyle

I ASSume you are happy with simple spectral info (RGB) for your Radiance model? If so you could do this on the cheap and easy with a MacBeth color chart and the macbethcal utility in Radiance. Just sayin'.

P.S. I know we're all lighting peeps, but recent research suggests the way to avoid Alzheimer's is cholesterol. Brain by bacon!
P.P.S. I may have oversimplified the current research, a tad.
