Retina vs Non Retina Photos

This page shows the resolution difference between retina (4K) and non retina photos. The first photo of each pairing shows the lower resolution image and the second displays the higher retina-quality image. If you look at the meta data in the lower right hand corner, you can see the images dimensions. If you don’t have a retina screen (4K), then, you probably won’t see a difference in image quality.
