[Radiance-general] pfilt: picture too dark or too bright

[Ignacio Munarriz]

hi Giovanni, the test01_sky.rad file includes the bright function 
definition of the sky but does noy apply it to any geometry, probably 
you need to include the sky definition, i cant try it because i have not 
the perezlum.cal file

skyfunc glow sky_glow
0
0
4 1 1 1  0

sky_glow source sky
0
0
4 0 0 1 180

Regards,
Ignacio
