Nokia's latest ad for its Lumia 925 slams Apple for its own campaign, which said "More photos are taken with the iPhone than any other phone." That might be true, but at what cost? Blurry pictures, bad color and low light? In a series of comparison shots, one taken by the iPhone and one with the Nokia, the phone company shows that in this case, it's quality, not quantity, that matters. It's a fair point: Why should any photographer care how many people use the device he does? What matters to the user is the quality of their own pictures.
