About Image Enhancer
Auto levels stretches the tones so the darkest parts are black and the brightest white, which fixes flat, hazy or dull photos. An optional colour-cast correction balances the channels for yellow indoor light. The sliders then do the rest.
This is the same maths a photo editor's "Auto" button uses. It is not an AI model: it cannot sharpen a blurred face, restore an old photo or invent detail.
