When Apple announced the Retina display MacBook Pro, they made a number of claims about its improvements. Beyond the obvious improvement in resolution, these were a bit vague. I will be publishing an article on the reduced reflectivity of the screen later today. But first, I wanted to show the color gamut of the new Retina display, and compare it to that of my earlier 15″ Unibody MacBook Pro.
As you can see from the gamut graphs above, Apple has done much the same thing in moving to the Retina display on the MacBook Pro that they did when moving to the Retina display on the iPad. The gamut is no longer small and skewed; it is very close to sRGB. This means that non-color managed sRGB content, such as materials on the web, will be much more accurately displayed, and that the display will be more capable of displaying photos than earlier MacBooks, since even when earlier versions were calibrated, they could still only display about 70% of sRGB, rather than the whole sRGB gamut.
This gamut normalization and enlargement will do wonders for using MacBooks for photography work, and will even make advanced image editing possible. Other factors that are improved on the new Retina display will also be important, including its much improved viewing angle, and its reduced reflectivity. The Retina display is, simply put, the biggest advance ever, in laptop screens for photography and video work; and would be even without the resolution increase.
While the gamut of the Retina display is a good match to sRGB already, calibration made improvements to the white point and gamma which were crucial to getting good matching to a high end desktop display. Visual match to my calibrated desktop displays is excellent with the Retina display MacBook Pro.
