Sharpening tool (Topaz Sharpen AI like)


I wonder if it’s possible to have a tool similar to Topaz Sharpen AI. As DxO prime noise reduction is one of the best tool on the market, and it might have similar algorithm to identify borders.

The new Topaz tool is really impressive, such a tool would be a great improvement in DxO, but I guess it’s a complex one…



Hi alexh,

just had a look at it, but did not install, because it does (yet) not support RAW format. Also for me its not clear if this is now denoising or more a sharpening tool. Sound more like sharpening from the description. And if, I am wondering if the Sharpener from the Nik Collection are not doing the same job. Also here export to TIFF is necessary.


It is sharpening tool, which allow to reduce motion blur without increasing noise. Perhaps it was a bit confusing to talk about noise removal tool, but I just said that it may be a similar algorithm based on edges detection.

I was using Nik before DxO repurchase, and Sharpener doesn’t seem to allow reducing motion blur as new Topaz tool does.

The Topaz plugins and Studio and everything Topaz are unbelievably slow (the technical requirements are ludicrous 8 GB latest generation gaming card as a minimum for many of their plugins). It may be that this weird party trick also requires a crazy amount of calculation.

Diminishing motion blur does not sound like a core task for a RAW development tool to me, but more a specialised niche for something like Topaz Sharpen.

Topaz is using AI which creates new pixels. It predicts where pixels should have been depending on a great set of example images.

I tested it and could save some images with mirrorslap caused blur etc. It took 2-4 aminutes to render an image.

It’s working very good, but you need very fast hardware.

I really think that tools like these could be in the NIK suite, not in Photolab

Topaz Sharpen is the best sharpening tool I have ever used. It needs fast GPU for working. Nvidia Geforce RTX 2070 (2304 CUDA cores) is quite fast with it.


Rescuing images sounded great to me for awhile. And then it dawned on me. Learn better fundamental techniques. Carry a tripod when necessary. Shoot correct exposures. Not sure fixing bad photos is the market profile of DxO. Fits Topaz to a tee though. Topaz tools are incredibly slow and gimmicky. Every cent and ever minute I ever spent on their software has been a waste.

I’d hate to see DxO embark on this path.


But sometimes, like it happened to me, you don’t have a tripod with you, because early in the morning, biking on the way to school/work with my son and a super luna in a perfect scenery through a bridges pylon suddenly showing up. So free hand with a Nikkor 300mm, in a hurry and unfortunately a bit blurred. So will try what Topaz can “fix”, because this drives me a bit mad, that this shot wasn’t perfect.
But nevertheless agree with you in generell.
Super Moon again in 2 weeks and will not forget tripod again :wink:
Just tried and the moon still needs a new shot :wink:


Interesting usage scenario. Software as you point out won’t really fix the image, just patch it.

If you’re carrying a 300mm lens and the camera to go with it, I’d suggest throwing either a light monopod (Manfrotto traveller aluminum is just 500gr and about $50/€50) or a Rollei M-1 mini tripod (about $75/€75). Most of my glass is not IS including my 70-200mm f2.8 but if I think I’m going to want image stabilisation and don’t want to carry a tripod or a monopod, my Canon EF 35mm f2 IS goes into the bag. At longer focal lengths, the EF 100-400mm IS USM II.

Thanks for the advice, but it is not the whole story and tripods, also light weight (carbon) I do have enough. From the weather forecast I did not expect to see the moon. So I just took the camera for testing a place and view for maybe later on better conditions.
The next day I had the tripod with me but guess, the clouds blew up as so often the session :wink:
And sure no fix, but where to start if its a patch or a fix? But this would be another discussion about which tool is no cheating :wink:


Another option is to use a higher ISO to increase your shutter speed and use the PL prime noise reduction to get rid of ISO noise.


Sharpen AI would be a much appreciated addition to DXO. I use Topaz AI on some photos with certain lenses and it is remarkable. You have a choice of “sharpen,” “stabilize,” or “focus,” depending upon what is needed. It would be nice to have this ability integrated into DXO. Please vote for this tool.


Interesting that you raise this again RA.

Topaz Sharpen AI is certainly a remarkable sharpening tool. It not only sharpens (variably across the frame) but also compensates for camera shake/subject movement variably across the frame.

The other comments in the thread are to simply take a better photo. This is like saying you don’t need DeepPrime simply use a Phase One XT medium format and “what noise”. :slight_smile:

Topaz Sharpen AI uses AI to do its magic. Coincidentally DXO now have AI technology. This seems like a good possible fit, depending on the skill of the AI engineers.

Having class leading noise reduction and sharpening (probably easiest) and possibly movement reduction, all in RAW looks like a possible game changer. Adobe are integrating AI into their products and I have seen the odd comment that they may do something similar in PS.

Something for the development team to consider if it is within DXO’s skill set to accomplish? Topaz like DeepPrime needs a GPU to work well, but so does DeepPrime.

Worth considering.


I agree. It’s time for the DXO folks to put sharpening on the the top of their “to do” - list! :grin: :ok_hand:t2: :crossed_fingers:t2:

Plain old USM is good but nowadays we expect something more. Topaz Sharpener is one implementation, DXO should consider how to do its own.


If you have the lens module, Lens Sharpness does quite a lot to help and gives better results that USM.
