MORE INTELLIGENT. The Neural Engine of the iPhone has been given a boost to the A13 chip, which makes processing lighting fast, and this is good news for the camera. It paves the way for smarter HDR, giving you more natural looking photos, closer to what the eye sees. A more intuitive HDR means less overexposed areas and more detail captured. In the fall, a software update called Deep Fusion will use pixel by pixel technology to process photos, giving them the best possible, details, texture, noise reduction.
