The iPhone 8 Plus and the Pixel 2 use high dynamic range (HDR) image processing, combining multiple frames taken in quick succession into a single image. Landscapes on the Pixel 2 look brighter and sharper up close.
When the Pixel 2 gets it right, it can produce even better portraits than the iPhone 8 Plus. The colors in this shot of Frisco Fred are more accurate, there's more detail in his face, and I liked having a wider angle to chose from.
The iPhone uses a quad-LED True Tone flash and its new Slow Sync technology which allows for a slower shutter speed and a short burst of light from the flash, together producing a more even exposure throughout the photo. The light here seems more natural and you can see more of the foreground, although you do lose some detail in her face.
The Mirror Maze looks sharp in this shot and the colors look just as vibrant as in real life. This year Google added a faster f1.8 lens, which lets in more light than last year's f2 model, and it added built-in optical image stabilization (OIS) that holds the camera steady to counteract shaky hands that often spoil shots in dim conditions.
