Can I calibrate my Macbooks screen?

You calibrate a notebook the same way you calibrate a desktop. I haven’t calibrated my macbook, but I know others who have used my old photography professor’s spyder. He used to calibrate the desktops in the digital darkroom once a semester, and if you happened to be about with your laptop he’d do that for, you, too – same process.

You don’t need a Spyder with a Mac – just run through the calibration process.

Calibration is under display in system prefs. From apple.com:

Using the Display Calibrator Assistant in Mac OS X:

1. From the Apple menu, choose System Preferences.
2. Click Displays.
3. Click the Color tab.
4. Click the Calibrate button.
5. Click on the Expert Mode checkbox.
6. Follow the instructions, and save the custom profile when finished.
