A couple of weeks ago I wrote a piece about what the then rumoured 5K iMac would mean that for photographers, and how you would now be pixel peeping on such a display even just looking at images. It was sort of a tongue in cheek piece, but now that the Retina iMac is real, I thought it would be important to have another look at the implications of a 5k display for photographers. If you're considering one of these new iMacs (I know I am !) then there are a few things you may want to ponder first!
