[Radiance-general] HDRI - Camera Response Curve

[Jack de Valpine]

Hi All,

Happy New Year first off.

I am making a first pass through the "High Dynamic Range Imaging" book 
that Greg co-authored. I am wondering about methods for generating a 
good response curve for a given camera. The book gives a variety of tips 
and suggestions, however I am curious about good scenes.

In a prior email footnote from Greg (a faq item relating to camera 
response curves and Photosphere), he suggests shooting a scene looking 
out a window during daytime with about 10 exposures. What about shooting 
a controlled scene such as a Macbeth Color Checker or a Kodak gray scale 
chart (can't remember the name of this) outdoors under daytime 
conditions or using some type of interior fixed lighting setup?
