Just got a new high res retina display Mac. Having fun with how great photos look on it, but I notice that when I export and look at the photos on another machine or even in certain apps like facebook, they look terrible - very soft, loss of contrast, etc. Basically they look magnified to 200%.
I'm guessing it has something to do with how I might need to export given the high resolution of these machines, but not sure what I should be doing. Its great and all to see my photos look so nice on my machine, but if they look lousy when I share then no point.

Thanks. I've tried exporting from both iPhoto as well as Lightroom 4.0. Same result. When I look at the file in the Mac's image viewer, looks very small (at 1,000 pixels) and very sharp and like I would expect. When I attach to an email and look at it on a different computer, it is now double the size and looks terrible. If I upload to flickr or facebook and look at it on my Mac, same problem.
I think it has something to do with the higher resolution of this Mac which other applications cannot process, but I don't know how to get around it.
I used to use a PC and used Lightroom or Capture NX to export, and didn't have this issue.

The Mac itself doesn't have a higher resolution in the way you've described. A file is a file is a file. The resolution of the file does not change when you move it to a different computer. Rather an increased resolution monitor packs more pixels into a given area making the image appear sharper. This maybe an over-simplification but that's how I understand it and explains why your images appear 'twice the size' on a lower res monitor.
You mention 1000 pixel wide image, well that's not a particularly large file. The 15" Retina display is 2880 px wide so a 1000 pixel wide image is going to be small as you describe (at 100%).
I'm sorry I don;t have an answer for you, it's tough to diagnose without being there, but I doubt if the export issue has anything to do with the retina display other than the relative appearance of the image against a lower res screen. Instead I'd look in the Export settings to find a solution.

Ok - I think I'm getting closer, but still am not sure. When I export and look at the file in either iPhoto, Lightroom, or in the native Mac Preview/Image viewer, it looks as I would expect. A 1000 pixel wide image looks quite small on the high resolution monitor. However, if I open up that same file through Safari (just by browsing to it), it now looks 3x bigger and of course and much less sharp. If I upload the file to my website, and look at it from another computer, same thing.
I don't really know how to adjust for this, but hopefully it is the type of information that will make it obvious to those trying to help me.
