How does PS use a monitor's profile?
I edit and print a lot of images with Photoshop. I understand why I need to calibrate my monitor regularly to have confidence in my editing and printing. What I don't understand is why I need to identify the monitor profile to Photoshop in the Color Settings window. I've been told that the monitor profile contains "target values," not the actual "physical values" of the monitor. If this is true, it must mean that when the physical values of the monitor drift over time, Photoshop cannot dynamically adjust what it displays by referencing the monitor profile. True? If so, then linking Photoshop with the monitor's profile must have a purpose that I don't understand.
