I am going to buy a Pantone Huey to calibrate my Macbook display. I do photography and work with a printer so I need accuracy. I work in sRGB. I am confused though. When I calibrate my display what am I actually doing? ...I want to show sRGB accurately, so when I calibrate my monitor, am I calibrating it to sRGB specifically or am I calibrating the monitor to just be accurate piece of hardware in general? Its confusing because for one of my displays, I have a choice between many existing, calibration profiles--why so many? I don't get it.
