There is a SWEET FREE ap to let you preview and look at radiance values.. called HDRview
for windows..but may work on macs? dunno maybe macs can run exe files or thru emulator? so no gaurantee will work on mac
(I didnt author this program but have used it for YEARS its AWOSOME very fast way to look at hdr files and change exposure and get pixel value readouts form your .hdr..)
http://www.debevec.org/FiatLux/hdrview/
the download is a zip 3rd 4th paragraph down on this linked page..
Its just the HDRview.exe zipped.. at least thats hows ive had it for years.. and I but that in my c:progrmafiles directory..
I right click on a .hdr image and say open with>choose program... and the BROWSE to the programfiles directory selecthe the hdrview.exe AND MAKE SURE TO CHECK: always USE the selected program to open this kind of file (in the open with window)
now everytime i double click an .hdr it opens it quick with hdrview.exe...
AND you can mouse over parts of your .hdr image and On the TOP left of the WINDow will give you readouts.. of your pixwel location.. and MOST important your color info for that pixel.. in the streetatdawn.hdr (http://resources.maxwellrender.com/) (the sun is a value something like 21,000.00 15,000.00 11,000.00 !!! wow thats intense..
with HDRview.. you can use the "+" and "-" keys on your keyboard to go up/down in expoure as weel as other shortcuts explained in the html above. (or right click on .hdr image and it will give you options.. like zoom in/out) you pan your image by clicking and draging it..
