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 five 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.
Standard v2
A new beta model which will replace Standard for low-to-medium blur images.
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 four AI models, a Strength slider, a Clean slider, the Subject Only toggle, and the Edit Subject button. Control the sharpen effect with these options.
- Strength: increases detail. Too much sharpening can create an unrealistic result.
- Minor Denoise: removes noisy pixels that hide details. This is for the Standard, Lens Blur, and Motion Blur models.
- Subject Only: this toggle controls where sharpening is applied. Toggled on, only the subject is sharpened. Toggled off, the entire image is sharpened.
- Edit Subject: opens the masking controls to change the subject mask.

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 Minor Deblur slider
- Enable Enhance Resolution and increase the Minor Deblur slider
The Remove Noise - Minor Deblur slider increases sharpness for the entire image.

The Enhance Resolution - Minor Deblur slider performs a slight sharpening on the entire image.
