Sharpen AI v2.1.8

Remember that Stabilize is only for camera shake. It won’t fix any other situations such as focus or general softness.

It also fixes perfectly motion blur of an animal/bird due to insufficiently short shutter speed (as shown in the pigeon photo on the program cover, by the way). For this reason, I use this mode most often.

Actually it is “Sharpen AI’s Stabilize module has been trained to reverse motion blur and make handheld images look like they were taken from a tripod.”

But if it works for you then you should keep using it in that way.

I respectfully disagree, if you look at the product page and scroll down to the description of the stabilization module:

“Animal Photography
You can pose people, but it’s much harder to ask animals to stay still! Use Sharpen AI’s Stabilize module to correct camera shake and the inevitable motion blur you get from fast-moving subjects.”

And down from that a good example image of a head of flying duck. That’s how it works, and works very good.

Try Focus mode it works better in situations where the subject is blurred.

Blur because of poor focus and motion blur are different, and require different algorithms. I’m on these plugins for >1.5 years, and know what works when. I’d post an example but not allowed to do so. Anyway, my example would be very similar to that duck head on the Topaz web site. This motion blur cannot be fixed in focus mode at all. Cheers.

Focus mode would be a poor choice in this case (as described) because it doesn’t handle motion blur well. On the other hand, Stabilize mode can also work well on non-motion blurred images, as it tends to create fewer artifacts.

I don’t see the relevance of what stabilize mode is used for when the discussion was about banding artifacts being introduced by GPU (but not by CPU). It’s clearly something that needs to be looked at and fixed as a priority.

That banding shows up in Stabilize mode only, hence the relevance.

Understood, but I meant when we were talking about the banding issue with Stabilize, not sure why AiDon interjected with ‘stabilize should be used for ____ situations’

My Sharpen 2.17 keeps exiting in the middle of a batch process randomly. Early on I though it was only when selecting Auto Mode and the mode changed in the middle of the batch.

Today I tried leaving Mode as manual, but the program still crashes/exits in the middle of a batch. Is anyone else experiencing this problem?

Hi, please go to Preferences and post what your Advanced Preferences are set to. Also you need to update your GPU drivers as it is our of date.


Here are my advanced preferences:


As of 10/4/20 the driver I have installed was supposed to be the latest stable version, there is a less stable version “vR455 U1 (456.38) New Features Less Stable” is that what you are thinking about?

OK, then don’t bother updating the GPU driver but have you tried switching to GPU with Medium or even Low memory consumption?

And do you have a log available from the last run that crashed?

It should be in the “ProgramData\Topaz Labs LLC\Topaz Sharpen AI\Logs” folder so, if you do, change the extension to .txt and upload it here please.

I switched to GPU with Medium. I did a batch of 20 images and it ran fine. I’ll run some bigger batches tomorrow and post the log if it fails again.

Thank you.

I did a run of 100 images this morning. They all ran fine without Sharpen exiting. I did choose Auto for both Mode and Settings. The only thing is that there was no change of mode in the run, only sharpen.

An added advantage with that using GPU medium memory usage the program is processing faster than before.

Interestingly I used reset and the program automatically chooses to turn of GPU and use Vino. I am leaving it with GPU on.

Thank you for your feedback.

I don’t know if it was like this before V2.1.8, but in Split View, the bar between the views is just a fuzzy white line. If your image is mostly white (E.G. an image of a text document with white background) the bar can be impossible to see. The same is true for DeNoise AI, so I guess it’s been “a thing” for a while.

In Adjust there is a thin black border around the white line which ensures it is visible regardless of the colour of the image.
