Here's what I feel on the two instrument types;
Both are only as good as the software that drives them. Counting and
measuring the low frequency photons at black or near black leans towards the
colorimeter. The colorimeter has smooth or smoother response filter for what
the eye sees. The spectrophotometer has possibly a more accurate absolute
value reading. The colorimeter can do a better job consistently in many
situations where the monitors are less than optimum (resolution, refresh
rate etc). The colorimeter is solid state and quite robust , less expensive,
thus an advantage of portability.
From what I see with the Sequel "Squid" (LaCie BlueEye) and the Gretag i1
Match Pro the calibrations are better with the colorimeter for both LCD and
CRT. With LaCie EyeOne there are all levels of grey even the difference on
the CRT at 0 to level 1 increment.
On the LCD there will be black adjustment (bias) on the new Mitsubishi's,
probably others will follow suit. Then we'll hopefully attain the same black
response on LCDs.
