Sharpen
The Sharpen filter detects existing details in the image and uses them to recreate details lost to blur.
Use it to save your blurry images caused by:
- poor focus
- movement during shooting
- shallow depth of field
- poor lighting conditions
Sharpen uses the subject mask.
Models
Topaz Photo AI comes with two sharpen models, each trained for a different situation.
Standard
Best for low-to-medium soft and blurry images. This model is for all-purpose sharpening.
Strong
Best for medium blur and out-of-focus images. This model performs a medium strength sharpening to bring the image into focus.
Lens Blur
Good for medium-blur and out-of-focus images. This model performs a strong sharpening for blurry images.
Motion Blur
Good for medium-blur and streaking in images. This model performs a strong sharpening to correct movement.

Controls
Enable/disable Sharpen by clicking the toggle.

When turned on, Sharpen displays two AI models, a Strength slider, a Clarity slider, and the Subject Only toggle. Control the sharpen effect with these options.

The Strength slider increases detail. Too much sharpening can create an unrealistic result.
The Clarity slider will clean up noisy pixels that hide details. This is for the Standard model only.
The Subject Only controls whether the subject mask is used for sharpening or if the entire image is sharpened.
Alternatives For Sharpening
There are two alternatives if Sharpen over-sharpens the image or a low sharpening is needed:
- Enable the Remove Noise filter and increase the Detail slider
- Enable Enhance Resolution and increase the Remove Blur slider
The Remove Noise Detail slider increases sharpness for the entire image.

The Enhance Resolution Remove Blur slider performs a slight sharpening on the entire image.
