How To Create iOS 7 Parallax Wallpapers For iPhone, iPad And iPod Touch

Step 1: Source your desired image. Although it’s not an absolute must, you’ll want to be working with an image larger than you actually need, so you can crop it down to size without degrading the quality. You can grab the image from anywhere – the Internet, or even your own photos – to find the perfect backdrop.
Step 2: If the aspect ratio happens to be correct for what you’re working with for your device, then resize, and if not, then select the appropriate area as per the aforementioned resolutions, and crop. There are a plethora of different apps you can use for Windows and Mac, including Photoshop, The Gimp, or if you’re feeling really adventurous, MS Paint.
Step 3: Next, you’ll need to save the image to your device.
Step 4: Finally, set the perfectly-sized image as your wallpaper, and simply enjoy the crisp, elegant effect.
