Exposure and how to fix it
Exposure is the amount of light a camera captures, set by shutter speed, aperture and ISO. When a scene is lit unevenly — a backlit portrait, a room with a bright window, snow or a beach — the camera's metering often guesses wrong, and the picture comes out underexposed and murky or overexposed and pale.
The exposure slider works in stops (EV) from −3 to +3, in steps of a tenth: +1 EV doubles the light, −1 EV halves it. Unlike a simple brightness slider, it scales light in linear space the way a camera does, and bright areas roll off smoothly into white instead of clipping flat. It works best on moderate mistakes; areas that are pure black or pure white in the original have no detail left to bring back. Saturation and warmth sliders help restore colors that faded or turned cold.
For separate control over shadows and highlights, open the photo in the editor and use curves or levels.
