I understand that colorometers are faster than spectrometers, and so most calibrators profile their colorometer and then use that as their primary device. I just want to know if speed is the only reason or do spectrometers get inaccurate when reading low light readings?
The reason I ask is that I rented a Colormunki and did two TV's in my house so far. I profiled my Calman X2 Colorometer off of the Colormunki, then used the X2 for my calibration. Once I was done, I check the grayscale and color gamut with the Colormunki. First, I found out the Colormunki is not that slow - slower than the X2 at low light levels, but perfectly managable for the DIY'er. Second, the readings were very close to the same as I got from the X2, but were a little further off in the low light levels of the gray scale. I want to know whether I can just use the Colormunki and adjust the lower part of the grayscale or should I trust that part to the X2 more.
Thanks for any help.
