You can find information about camera calibration on this site:
http://luxal.dachary.org/webhdr/calibrate.shtml
You have to find the response curve for your individual camera.
With this you can create reasonably accurate HDR images that
could be compared with each other.
Because of the image manipulation that goes on inside of a
digital (consumer) camera, I doubt there is a straight forward
relationship between two picture taken by different cameras.

Hi
Two different cameras are used for taking the same scene at same time and
same day. If we know the each camera ISO value, shutter Speed and f-stop
value and the HDR pixel value of the images produced by them then what is
the relationship between them with respect to captured outdoor scene
radiance value or how one can compare the radiance value captured by both
camera. I will appreciate if one can give some mathematical relationship or
formula.Best Regards, Brajesh Lal
