Wallpapers for iPhone Duo, outer and inner screen

Apple lists the iPhone Duo's outer screen at 1398 × 2034 pixels (460 ppi) and the inner screen at 1878 × 2670 (430 ppi). Both are close to 1.4:1, far from the 19.5:9 of other iPhones, so a regular wallpaper loses a good part of its top and bottom on them.

What works: pictures whose subject sits in the middle, and patterns that have no top or bottom. Gradients, contour maps, flow fields and starfields crop well; a landscape with its horizon low does not.

A note on sharpness: the wallpapers here are made 1320 pixels wide, so for the 1878-pixel inner screen the Get it button enlarges them about 1.4 times. Smooth gradients stand that without visible loss; for a perfectly sharp inner-screen file, make a gradient at 1878 × 2670 in the maker.

• Marble tide silk gradient
• Ocean glass silk gradient
• Contour lines, forest
• Flow field, sea
• Prism conic gradient
• Stephan's Quintet
• NGC 346, a nursery of stars
• Bokeh, cool
