<DIV><FONT face=Arial size=2>I am primarily interested in the image analysis
features of radiance but have not found any step-by-step instructions for
installing the software on a Mac G5 running Leopard. Not interested at this
point in the rendering functions. Very interested in using HDR photography
for luminance measurements. Would appreciate any references covering these
topics. Unix and Matlab naive, although I suppose I could learn!</FONT></DIV>

<DIV><FONT face=Arial size=2>I have reviewed several articles including Inanici
& Galvin 2004 and Beltran and Mogo 2005.</FONT></DIV>

<DIV><FONT face=Arial size=2>PS There is an useful program, ImageJ, developed at
the National Institutes of Health that allows for luminance calibration of pixel
values and arbitary selection of image areas for computation of average
luminance and other functions. I have used this successfully for contrast
measurements of scene objects; however it is limited to LDR images. It is a free
download.</FONT></DIV>
