Outside the CNET office: iPhone 4S
Though it doesn't have the hype of Siri, the iPhone 4S' camera is one of its best features. Now with a resolution of 8 megapixels, the iPhone 4's shooter offers huge improvements over the iPhone 4's. It has an f/2.4 aperture lens, a sensor that allows 73 percent more light than the iPhone 4 camera, a hybrid IR filter for better color accuracy, and improved auto white balance.
I know that's a lot of techno-babble, so to show just how the iPhone 4S is different, I shot a series of 10 photos using both phones. I then showed the photos to Lori Grunin, CNET's senior editor for digital imaging. She was quick to reply that the iPhone 4S is vastly superior to the iPhone 4 in several ways. White balance is much better and the memory colors (greens and blues) are far more accurate. She also said that the tonal range for the 4S is more open, which gives the images a lower contrast and shows more detail. That's the brief scoop, but I added more observations throughout the photo gallery.
Here you can see that colors in the iPhone 4S image are very sharp. There's also great detail and little image noise.
