It analyses the image’s tonal distribution and stretches it to use the full range, so the darkest areas become properly dark and the brightest properly bright. That single correction fixes most of what makes a photo look flat — haze, overcast light, and images shot through glass.
On photos that are already well exposed, where it makes little difference, and on images where flatness is deliberate — soft, low-contrast portraits or a misty landscape can lose their mood entirely. It also cannot rescue blown-out highlights, since that detail was never recorded.
Use our Adjust tool, where brightness, contrast and saturation are separate sliders with a live preview. Auto-enhance is for speed — a single click across a batch of holiday photos. Manual adjustment is for when a specific image needs a specific correction.
