The iPhone X is exceptional for stills, achieving the best Photo sub-score yet at 101 points. Compared the iPhone 8 Plus, the X’s improved telephoto lens boosts results in several areas, notably Zoom, Exposure, Color, Texture, Noise, and especially Artifacts, Outdoors, exposures are outstanding, with great dynamic range, impressive skies, good fine detail, and punchy color rendering. A natural-looking bokeh effect in Portrait mode is another strength.
