Dear all,
I would like to understand how ra_tiff and pcond work.
I'm using pcond specifying contrast (-d) and max luminance (-u) of my
display. Then I transform my picture (.pic) with ra_tiff to obtain a tiff
picture.
Does somebody know which function is applied in ra_tiff to transform a .pic
in a .tif ? It seems that my picture in .tif has a mean luminance greater
than my .pic
Thank you in advance for your help,
Coralie

The pcond command does not maintain the original values of the image,
but rather adjusts them according to a visual interpretation of what the
image should look like when printed or displayed on the screen. If you
need to do exposure adjustment but preserve original data try pfilt.
