NBC News photographer Jim Seida spent a day shooting stills?with the iPhone 5, along with the iPhone 4S, iPhone 4, the new Samsung?Galaxy S III and a high-end point-and-shoot from Nikon, the P7000. The results? While the iPhone 5's 8-megapixel camera performed well, it did not noticeably?outperform its most recent forebear. But there was one way that the iPhone 5 clearly?bested the 4S.
The key to the test was that Seida didn't use any special apps, just the native camera mode, and the only manipulation he did was to tap the same spot on the screen each time, to focus the camera and determine the exposure.
By?comparing low-light portraits of Seida's colleague, you can see a slight reduction in noise compared to the 4S, but the picture itself is a tad?underexposed, too.
While noise was also not a problem for the Samsung Galaxy S III's 8-megapixel camera, it did lag in detail (and also appeared somewhat dim).
Outdoors, Seida challenged the phone-cams with high color contrasts and an abundance of light. The only noticeable difference between the iPhone 5 and 4S was background detail, which could be explained away by multiple factors. (Besides, having a slightly blurred background is generally preferred.)
The Galaxy struggled a bit with exposure ? towards the top, the meter is?too washed out.
The results aren't surprising.?One of the biggest leaps for the iPhone 4S was its camera ? just look at how the iPhone 4 did in the above experiments, paying special attention to the noise in the low-light shot and the over-saturation in the outdoor shot.?Meanwhile, the specs on the iPhone 5's camera never suggested a quantum leap forward.?
But Apple has promoted its camera as improved ? going so far as to say that the new A6 chip has an image signal processor that can deliver more brightness to a picture, up to two full stops. In our real-world and controlled testing, we have not seen any significant difference.?
Consumer Reports had similarly unspectacular results in its comparison test of the iPhone 5 and 4S cameras.?Though usability is better, due to the phone's overall?faster performance and bigger screen, outdoor shooting showed a?"modest step up," yet "the claimed improvements of the iPhone 5 in handling low-light shots were not apparent in our tests."
When it comes to the front-facing camera, however, the difference doesn't require expertise to spot. The FaceTime camera on the 4S supports?"VGA-quality photos and video" in the 640x480 resolution, while the new one on the 5 brings 720p HD-quality video and 1.2-megapixel stills. Seida's self-portrait shows just?what that means:
