Hello, I am calibrating a Apple Cinema (the new 20" model). I am using Eye-One Display 2 with Eye-One Match Software. I am following guidelines published in ISO 12646, with some modifications for LCD. Here are the settings I am optimizing for: Monitor Luminance: Target 140 cd/m2 Monitor Gamma: 1.8 (mac) Monitor White Point/Temp: 5000K Room Ambient Light: 32 lux Light Booth Light: 2000 lux Light Booth White Point/Temp: 5000K And to get to the point, my question is, it seems that even at 140 cd/m2, my monitor does not match the overall brightness of the Light Booth at 2000 lux. I find it to be too dark overall, and have to either turn up the monitor brightness, or turn down the light booth dimmer. I find this interesting with the Apple LCD because CRTs have typically had an even lower target (around 100 cd/m2) for soft proofing. Is 2000 lux too high for the light booth (even though recommended by ISO 12646)? It seems accurate in that the color temp is right on 5000K at that level... Is there some other target level other than 2000 lux that I should shoot for on the light booth? Or should I pump up the brightness on the display? And to what luminance? Thanks in advance to any responses.
