Preslav, a member of the PhoneArena team since 2014, is a mobile technology enthusiast with a penchant for integrating tech into his hobbies and work.
The camera is one of the most important features in a smartphone — we use it to capture memorabilia, to video chat, to share funny sights in our Instagram stories, show off the 'fit, or whatever else. Sure, some users have other priorities — camera often ranks third on the importance list, behind battery life and display. But, it's a huge part of the device, and there's a good reason why most of us no longer own a point-and-shoot camera.
Well, mostly yes. But since small sensors and small lenses can only capture so much light, smartphones rely heavily on software to clean up, sharpen, and enhance the photos. It has become a reality of modern times that we are mostly judging the software post-processing that a smartphone does automatically, instead of the actual hardware.
Of course, every camera has a limit on how far it can go with its dynamic range — bigger sensors with big lenses can do better at this. Smartphones rely on our next point of discussion:In order to widen the natural dynamic range of the hardware, modern photography relies on HDR technology. What this does is — the camera automatically takes multiple photos at different exposures, and then intelligently stitches them together.
Skin tone — a camera could have pretty realistic colors when shooting objects, nature, pets. But very often, human skin tone can look off. You can come out yellow-ish or desaturated, appearing pale and sickly. Or, you can come out looking pink, as if you were ashamed of the camera. Funnily enough, even top players like the iPhone can give you a pink face if the sunlight hits the right spots in a scene, tricking the algorithm to overtune the colors.
The algorithm carefully smudges the small grainy spots, tying pixels around them together to make them disappear. And thus, fine details that these grains covered will also disappear. Facial features, grass strands, lines through trees and rocks — nothing is safe from The Great Noise Reducer!So, a"good" phone camera will try to strike a balance between noise reduction and the complete eradication of details.
