As I'm totally overdue for an upgrade, I've been reading the forums on and off since the launch of the new MPB(r) line. I found answers to most of my questions, but I'm pretty unclear on a thing or two. Tried asking around, but got no clear answers so far. To put it simply, my situation is the following: The nature of my business makes me depend heavily on my clients seeing the photos I upload or send being as close as possible to the original colour and sharpness seen on the monitor I edited them on. Small differences can have massive impact here they can literally make or break a deal. Would I be correct in assuming that pictures that were edited optimized on a retina screen wouldnt suffer in sharpness when seen on other, lower resolution screens? For a specific example, lets say I edit and export a low-res photo ready for the web or e-mail say a 500 x 500 or 1000 x 1000 px image. If the photo looks sharp on a retina it was edited on, will it look just as sharp on standard lower resolution panels? In other words, can I assume that beyond modifications of whites/blacks/contrast photos from a retina screen wouldn't suffer in sharpness when sent to other lower DPI screens? Also, another question, but a bit less urgent Is there a way of encoding colour profiles/exact colour coordinates into a picture, so as to make the colours appear equal on all screens? In essence, force a screen (through a browser) to show the colour coordinates that were seen on the one the picture was originally edited for colour? Of course, allowing for different brightness settings and contrast. Im not that apt screen-wise and thats something Im working to change. So helping me out with this, if possible, would really be appreciated.
