The iPhone’s new selfie camera, also called the Facetime camera, has three-and-a-half times the pixel density of its predecessor and boasts Retina flash. While this will make for better lighting, it might not be popular with users who blind themselves taking their first selfie at close range.
Apple may also win back the “best camera” title from Samsung, with a 50% increase in pixel density to 12 megapixels on its rear-facing camera. But pixel count isn’t as important as things like lens quality, imaging software, sensor quality, and exposure control. Professional photographers may notice a difference, but, then again, they buy professional cameras. Casual users won’t see enough of an improvement to warrant an upgrade.
