Fortunately, the latest-model iPhones feature camera resolutions up to 12 MP; and DSLR cameras often feature 18 MP and up, so you don’t need to be a professional photographer to start with a high-resolution image.

Another name for 7.2 million pixels is 7.2 megapixels (MP); which means you’ll need a minimum 7.2 MP camera to get the best resolution for your 8” x 10” photo.
