Topaz Sharpen AI uses machine learning (AI) techniques to remove or reduce image blur and shake.

Depending on the type of blur/shake it’s been one of Keith’s go-to tools for image processing.

The localised fixing of blur is extremely useful for fixing the complex aberrations of shifted lenses, where problems only tend to show in strongly shifted parts of images. Oh, and it’s handling of camera shake is useful, given Keith’s liking of hand held photography.

Topaz Sharpen AI

Up to April 9th 2021, there is an offer on Sharpen AI. Use Code ‘SHARPEN15’ for a discount.

Also available “Image Quality Bundle”. It includes Sharpen, Gigapixel, DeNoise, and JPEGtoRAW. The retail price is $359.96, but it’s on sale for $199.99. (More than $150 in savings).

Sharpen AI V3

See the changelog for Sharpen AI below for precise changes.

I use it almost entirely from within Photoshop (still CS6), as a plugin. It will work standalone and with other applications.

This is tool that fits in well with liking for hand-held photography. Every so often I’ll get a bit of shake I don’t want – it happens, especially with higher MP sensors.

Even for my architectural photography, a tripod can’t stop some of the distortions I see with with strongly shifted lenses. Topaz AI has meant that my old Mamiya M645 lenses are something to include in my camera bag.

For more about how and why such processing/sharpening is important see the reviews at:

It proved very useful when testing the Laowa 15mm shift lens at full diagonal shift, when the only significant blur was concentrated in one corner of the image.

Sharpen AI V3

The new version defaults to auto updating the preview sample. This only takes a few seconds, even on my oldish Mac, but was easily changed back in the preferences.


One useful feature of the software for myself is that there are auto settings buttons that give you suggested starting points for slider settings. When working from Photoshop I’m very aware that I have the ability (via masking) to turn down sharpening in areas it might be a little strong.

The software handles soft out of focus areas very well, but if you only need part of an image sharpening, it’s worth looking at the masking feature. In Photoshop I duplicate a layer, sharpen that and then mask back in what parts I need. This is particularly useful when making large prints, where smoothness and sharpness can work together to give a much better impression of detail. With older images the sharpening can pick up sensor defects in flat areas – these I don’t want any sharpening applied to.

A couple of examples show uses of Sharpen AI

This first one was taken on a shoot at a factory making fairground ride cars and the like. The guy at work was hand finishing a prototype before making moulds for production.  The light was quite low, I was using my EF24-70 2.8L lens on a Canon 5Ds (50MP). At wider apertures the lens has a bit of softness, but the subject was also moving.

This view (100% crop from a 50MP image) shows more general sharpening on the clothing, but extra motion removal on the hand.

A look at the face shows sharpening and the noise removal in the flat areas.


Once the image is processed (3-4 minutes on my 2010 Mac) the improvement is very noticeable.


The whole image.


Lens shift

This photo was taken at extreme diagonal shift, meaning the camera was pointing down the walkway.


The vignetting I can deal with in Photoshop, but the far corner is showing distinct softness. Stopping down to ~f/11 has helped, but much further and the excellent sharpness in the rest of the image will be reduced.

This view (at 200%) shows the sharpening preview.


The software works really well in dealing with lens softness, and if like me, you like re-using old lenses it can be superb for when their deficiencies decide to get in the way, rather than ‘add to their charm’.


The update is a free one for registered users.
