Brightness in photography
Brightness is how light or dark an image looks overall. Photos taken indoors, at dusk or against the light often come out too dark, while a bright sky or a flash can wash them out. Changing brightness scales the value of every pixel by the same factor, which is the quickest way to rescue such a shot.
The slider starts at 100%, the original. Move it right to lighten and left to darken; values between 80 and 130% are usually enough, as stronger changes flatten the shadows or blow out the highlights. Two extra sliders adjust saturation and add warmth, since a brightened photo can look a little dull and cold.
The file keeps its original format and size, and the preview shows the result instantly.
