I have both Photocal and Optical and have profiled 5 monitors at my
workplace. Following ColorVisions suggestions I have them at a total
luminance of 90 cd/m2. We work in a quite dim room to avoid reflections so I
am wondering if the total luminance should be lower? Is the recommended
range of 85-95 cd/m2 for "normal" ambient light - which is at the same, or
just a bit lower intensity as your monitor? Or am I just beeing paranoid...
Many thanks for your comments
