What is computational photography, and how it it making the iPhone and Pixel cameras better?

To work around this, companies have had to get creative. The biggest advances have all come from ways to stack or combine multiple images in the phone. Depending on how many images are stacked, and how clever the algorithms, this technique can be used to reduce noise, boost the tonal range, take clear shots in the dark, or even artificially boost resolution.

These techniques were known to photographers, and they’re doable in programs like Photoshop, but the success of computational photography is having all these tricks happen seamlessly and nearly instantaneously, inside your phone. All you have to do is click the shutter, and the software handles the rest.
