So how are the screen colors? Are they better than on cinema display?
I previously owned the 27" iMac. To my knowledge, Apple uses the same display in the 27" cinema display. I've found that colors and contrast are more accurately represented on the retina display in the new MacBook Pro than on the iMac. The processing speed difference was also minimal so I sold my iMac.
I use the 5D Mark III. I took this shot with these shots with the 16-35mm f2.8 II Lens
Yes, the retina display is not what makes these photos look the way they do. I processed them with a tone mapping technique similar to Trey Ratcliff. So thanks for mentioning him! He's one of my photography idols
