I haven’t purchased an NEC Spectraview monitor yet, but I can calibrate my iMac monitor at EV 8.5 brightness. (It’s not the same, I know.)
In a dimly lit room, the low values on the monitor appear too light, too easy to discern. In a normally lit room (EV 8.5) the shadows on the monitor look appropriately dark, as dark as the print examined under EV 8.5 lighting.
So why do we recommend working in a dimly lit room ? Am I getting the wrong impression because I’m not using a truly calibrated monitor ?
