In December 2020, with the release of the iOS 14.3, the owners of iPhone 12 Pro (and ProMax), got to experience Apple’s new photo format, ProRaw. In simplest terms, the iPhone camera captures multiple image frames, picks out the best bits from these frames, and stitches them together in a photo with higher amount of data that can be manipulated for editing later. These are big files — about 10-12 times the sized on normal files captured by the iPhone.
On the Adobe Photoshop side:
The term ‘Super Resolution’ refers to the process of improving the quality of a photo by boosting its apparent resolution,” Adobe engineers write on the company blog. “Enlarging a photo often produces blurry details, but Super Resolution has an ace up its sleeve — an advanced machine learning model trained on millions of photos.”
The results are pretty amazing. Follow the headline link, keep in mind that the two base photos were captured with an iPhone. The crops used Photoshop’s Super Resolution machine learning to tease extra resolution and sharpness out of those originals.
