Yes, Tom is an enthusiastic theorist, so what he's saying is both interesting and true, but probably not applicable on a practical level...
My concern is that i would like to think that me and my clients are
seeing roughly "the same thing" when they look at my files...
Agreed....
I think that I can instinctively grasp the concept of color vision and
lightness versus brightness but how does this come into play when using
a calibration gear with a software only allowing you to set your own
black and white point in candela unit? Plus again, how does all this
relate to your display adjustment knobs?
Here's the scoop. If you run an LCD at a relatively high candela value for White Luminance, in a relatively light room, it will look (relatively speaking) the same as a much dimmer CRT, with much dimmer ambient light (and a warmer white balance as well, due to another variable in the eye). The Ambient Light functions measure your room lighting, and define WhitePoint and White Luminance target values that will make for this relative match, and the hardware controls are used to reach these defined monitor target values. Is that clear enough?
