iPhone photography has come a long way in the past 13 years. The original iPhone had a 2 MP camera that produced images that were 1600 x 1200 pixels. Today, the wide-angle camera on an iPhone 12 Pro has a 12 MP camera that can take shots that are 4032 x 3024 pixels.
Hardware advancements have played a big role in iPhone photography, but so has software. The size of an iPhone and physics limit hardware advances, resulting in diminishing returns year-over-year. Consequently, Apple and other mobile phone makers have turned to computational photography to bring the power of modern SoCs to bear, improving the quality of images produced by iPhones with software.
Computational photography has advanced rapidly, pushed forward by the increasingly powerful chips that power our iPhones. Every time you take a photo with your iPhone, it’s actually taking several, stitching them together, using AI to compute adjustments to make the image look better, and presenting you with a final product.
