Does sensor size still make a difference?

“We’ve seen huge breakthroughs in the computational photography techniques in the latest smartphones, as well as the launch of some excellent small sensors in more traditional cameras. Does that mean that bigger is no longer necessarily better?”

How to check & correct your autofocus: tips for fine-tuning AF to get sharper images

“Modern DSLRs generally rely on what’s called phase difference autofocusing: basically, a rangefinder scheme updated with new technology. But .. this technology uses a second optical path within the camera, independent of the lens-to-sensor path used to make the photo…. Given manufacturing tolerances and the routine punishment you visit on your camera, it’s possible that these two paths are slightly different. Sure, your autofocus oughta focus. But it could be off.”

Why smartphone cameras are blowing our minds

“There’s no getting around physics – smartphone cameras, and therefore sensors, are tiny. And since we all (now) know that, generally speaking, it’s the amount of light you capture that determines image quality, smartphones have a serious disadvantage to deal with: they don’t capture enough light.

But that’s where computational photography comes in. By combining machine learning, computer vision, and computer graphics with traditional optical processes, computational photography aims to enhance what is achievable with traditional methods. Here’s a rundown of some recent developments in smartphone imaging – and why we think they’re a big deal.”
