Sharpen Image — how it works

Make soft photos crisper with an adjustable sharpening filter.

What sharpening does

Sharpening increases contrast right at the edges — dark sides get a little darker, light sides a little lighter — so outlines and textures look crisper. It cannot recover detail that was never captured, but it makes a slightly soft photo look noticeably clearer.

How much

Start light and use the Compare switch. Too much sharpening creates bright halos around edges and exaggerates noise; for print and social media a light to medium amount is usually right.

When sharpening is not enough

For small, low-resolution or very blurry photos, the AI Image Enhancer upscales 2× and restores detail with a neural network — a different job than a sharpening filter.
