[Radiance-general] Obtaining proper luminance values in scene image generated using HDR sky-probe luminance data

[giulioandrea antonutto foi]

something that Greg and Santiago discussed a while ago (and wrote for us):

#!/bin/csh -fe # Undo any exposure to one or more Radiance pictures 
foreach i ($*) 
set expos=`sed -n -e 's/^EXPOSURE=//p' -e '/^$/q' $i | total -p` 
pfilt -1 -e `ev 1/$expos` $i > $i.$$ 
mv $i.$$ $i 
end

may be of help
