iPhone 6S Plus's camera takes on iPhone 6 and Galaxy S6: Outdoor photo shootout

We take the iPhone 6S Plus's camera around sunny West London to see how its outdoor shots compare to those of the iPhone 6 and the Samsung Galaxy S6.

Apple's brand-new iPhone 6S and 6S Plus are finally upon us, and one of the main areas that's been given a boost is the camera. On both models, the camera's resolution has been upped from 8 to 12 megapixels. The iPhone 6 was already one of the best phone cameras around, and it's capable of taking some truly stunning photos. That Apple had taken something already superb and made it even better was an intensely intriguing prospect.

As a photographer, I was very excited to take the new 6S Plus for a spin around an unusually sunny Ealing, West London to see how the new camera compares to the older iPhone 6, as well as its main rival, the Samsung Galaxy S6 -- another phone that we at CNET found to be a superb photographer's companion.

A quick note on resolution: All phones were shooting on full automatic mode, and at maximum resolution. For the iPhone 6, that's 8 megapixels, with 12 megapixels available on the 6S Plus. The Galaxy S6 offers 16 megapixels, although at max resolution, it takes its shots in a wider 16:9 aspect ratio, rather than 4:3 on the iPhones. In actual fact, the vertical number of pixels isn't all that different (2,998 pixels on the S6; 3,024 pixels on the iPhone 6S Plus). The extra resolution of the S6 comes largely from its extra width -- 5,312 pixels versus 4,032 on the                                                     iPhone 6S Plus.
