Tips for Creating Great Artwork for the Retina Display
If you merely scale up your existing artwork, you miss out on the opportunity to provide the beautiful, captivating images users expect.
Instead, you should rework your existing image resources to create large, higher quality versions that are:
More detailed. For example, in the high-resolution versions of the Safari and Notes icons, you can see details such as the accurate contours of the continents behind the compass and the torn paper left by the previous note.
Add detail and depth. Don’t hesitate to draw very small elements, because the high-resolution version of your artwork allows much more room for fine details. For example, a 1-pixel dot in your original image becomes a 4-pixel dot (that is, 2 x 2 pixels) in the larger version.
