Apple is always upgrading the iPhone camera, and the 5S line is no different. Apple has updated the entire camera system with a new five-element Apple-designed lens with an F2.2 aperture. The sensor has a 15% larger active viewing area, and rather than more pixels, there are bigger pixels. The pixels are 1.5 microns, as bigger pixels equal bigger pictures, and iOS 7 is designed to take advantage of the new camera system. The stock Camera app sets white balance, exposure, creates a “dynamic local tone map,” “autofocus matrix metering” with 15 zones, and does it all automatically.
There’s also a brand new dual LED system with two LEDS, one offers cool white tones, and the other is for warm amber tones. The iPhone can combine the two to balance out that flash to match with the color in the room, which is especially important for skin tones. There’s also a new burst mode to capture ten frames per second, and software can always capture multiple photos, combine them for light levels, and produce the best looking result. In addition to the photo camera enhancements, there are new video camera enhancements centering around a new slo-mo mode. The iPhone 5S can capture HD video at 720P at 120 frame per second. That also includes new automatic image stabilization. Finally, the panorama function can now adjust exposure level automatically as you pan.
