So why, then, would it be better to work with a 16-bit image? One word - flexibility. When you're editing an image in Photoshop, sooner or later, if you continue making edits, you're going to run into problems. The most common problem is what's known as "banding", where you've lost so much detail in the image that Photoshop can no longer display smooth transitions from one color to the next. Instead, you get an ugly stair-stepping effect between colors and tonal values.

The problem is amplified when saving for Retina, where there’s twice as many images, and the 1× images must match the 2× images precisely. The best solution I’ve come up with so far is: Build your design at 1×. Use copy merged to save all the 1× images. Duplicate the entire folder containing the 1× images. Use Automator to add @2x to all the filenames. Open each @2x image and run the Scale by 200% Photoshop action. This gives you a file with the correct filename and size, but upscaled content. Scale your main Photoshop design document by 200%. Use copy merged to paste the higher quality elements into each @2x document, turn off the lower quality layer, then save for web, overwriting the file.
