I recently bought a new 13 inch Macbook Pro with the Retina Display and was super excited to use it with Lightroom 4. I began to edit and export photos for airplane-pictures.net for upload. The website requires that the photos be a .jpg file between 1024px and 1600px on the long edge and less than 3MB. On my old MBP (Macbook Pro), I always exported photos with the same settings at 1280px on the long edge with 72ppi, and a quality of 80 and high sharpening for screen. I did the same thing with my new Retina Display MBP and the photos look terrible. There is an excessive amount of jaggies that make the image look really over sharpened and even out of focus before and after uploading. (I have tried adjusting quality, pip, and screen sharpening but they have resulted in no improvement) However, if I keep those settings, but I don't resize the image at all and leave the "resize to fit" box unchecked and is opened in Preview, the photos look beautiful, AND they are fit perfectly in my 1280px screen. So it's like the photo is automatically resized when I export it without checking the box and it seemingly fits at 1280px, however the website will not accept at the large proportions of something like 5363px × 3352px. Does that make sense? In short, when I resize the photo in export to 1280px, it looks awfully out of focus and over sharpened, but when I don't resize the image and open it in Preview it fits to my screen and looks gorgeous! Has anyone used Lightroom 4 with the Retina Display and figured out some sort of solution? Again, when I used these same settings on my OLD MBP the photos looked just as great.
Thank you in advance!
