Phone cameras can take in more light than the human eye


Phone cameras are an example of what’s called computational photography. Digital tools built into these cameras can enhance your images in real time.

Normally hidden, this depth data enables smartphones to apply effects such as artificial background blur to mimic the look of the northern lights against a night sky. Camera manufacturers like Nikon, Sony and Canon typically avoid tampering with the image, instead letting the photographer take creative control. While you’re taking a photo, AI tools will analyze the scene you’re pointing the camera at and adjust settings such as exposure, white balance and ISO, while recognizing the subject you’re shooting and stabilizing the image.
