[Radiance-general] Desktop radiance Glare Analysis: Pcond

[Lars O. Grobe]

Hi Ann,

first, Desktop Radiance is unsupported and has not been updated for 
ages. Avoid using it, there are better, supported software around based 
on current versions of Radiance.

Second, glare analysis is based on the pixel values. Thus I would not 
adjust anything in images that are supposed to be used for analysis. To 
make sure that you are working with original pixel values, use pcomb -o 
: pcomb -o filtered.hdr > raw.hdr and use raw.hdr as input for all your 
analysis.

But: Images generated by pcond -h can NOT be used for such analysis, and 
as far as I know, there is no way to revert the changes made to the 
pixel values. The idea behind pcond -h is to give a visual impression 
what an scene would be perceived like by a human observer, which 
requires changes to the pixel values beyond exposure settings.

Cheers, Lars.
