are also sharper. Sometimes, cameras overcompensate for low light by making the few points of light too bright. The 5S typically has those scenes properly balanced.
Of course, these improvements won't make all photos better. Many shots appear the same whether taken with the 5, the 5C or the 5S. In other shots, differences are subtle.
The 5S can also shoot slow motion video. You can choose the parts you want in slow motion and regular speed, and you can change your mind later. A burst mode lets you snap 100 shots in 10 seconds, compared with 40 seconds on the 5C. The phone picks out the best moments and filters out duplicates. The front-facing camera is better than the one on previous iPhones. It has larger pixels for low-light videoconferencing.
Many of these features are possible because of Apple's faster A7 processor. A companion chip, the M7, handles motion-related data without draining as much of the battery, something useful for fitness trackers. All this power is so new, apps taking advantage of them weren't available for me to test.
- IPHONE 5C (available in green, blue, yellow, pink or white; starts at $99 with two-year service contract, or $549 without a contract):
Plastic colors aside, the 5C is mostly the same as the iPhone 5 it replaces, with the older A6 chip and a main camera that's not as good in low light. Because the chip is slower, it couldn't do slow-motion video or take as many shots per second. But it does have the 5S's improved front-facing camera.
The 5C is for those who really want the bright color. If you can afford the additional $100 and can do with silver, gold or gray, get the 5S instead. The fingerprint sensor will make security less annoying, and the better camera will be more useful in documenting life. A hundred dollars isn't that much when you compare it with the full price of the phone.
