Camera
Samsung Galaxy S6: 16-megapixel rear camera, 5-megapixel front camera, single LED flash, optical image stabilisation
iPhone 6: 8 megapixel, phase detection, dual LED 'True Tone' flash
Photography is a big battleground for both these devices. The iPhone 6 camera is rated as an 8MP snapper but the internal optics have been upgraded and it's capable of some outstanding shots in all kinds of conditions. The big update is the iPhone 6's autofocusing technology, a.k.a "Focus Pixels." The camera decreases the likelihood of taking a blurry shot, thanks to the phase-detection autofocus system. The 6 focuses twice as fast than the 5S. There is also an option to capture 1080p HD at 60 fps, 240-fps slo-mo and time-lapse video. The front camera, also known as the FaceTime camera, is much improved. The 1.2-megapixel camera's resolution remains the same from the 5S, but now has a slightly faster f/2.2 aperture which gives a slightly better picture.
However, unlike the iPhone 6, the iPhone 6 Plus has optical image stabilizing technology, which enables the camera to compensate the natural motion of hand shakes to produce a clearer shot.
Samsung is also proud of S6's photo taking capabilities. The sensors in the Galaxy S6 series are notably larger both for the front and rear cameras. The front sensor is over 3 times better at 5MP and the rear sensor is a 16MP. Samsung has used the new f/1.9 aperture lens on both the front and rear cameras. The f/1.9 aperture lets in an incredible amount of light, which means you're going to get much, much improved pictures in low light situations. It is this f/1.9 aperture that enables the S6 series to produce low-light images that are better than the iPhone 6 camera.
