Has anyone tired the new AI noise reduction/image enhancement available for Topaz Studio?

If so, do you think it better than DxO Photo Lab's Prime NR and/ or Neat Image?

Thanks.
 
Solution
It seems that the only reasonable conclusions are two:

1. It works in some configurations an/or with some images, and doesn't work in other configurations and/or with other images.

2. Therefore try it for yourself.

Thanks to all of you for your posts that helped make this clear. I hope they will encourage On1 to look into the issue and see if it can be made to work over a larger range of configurations and images.
the only information I have is what was in the email, which I copied and pasted in my post.
Got an email today that I could download DeNoise AI and since I already had Denoise 6, that there was no charge for the product.

I had been really liking AI Clear, and am now trying to understand the placement of this product. Does it do everything AI Clear was able to do? I was really liking how it could make soft images sharper. DeNoise AI has a slider to shapen the image. I will need to play with the sliders more.

Topaz has FAQ section and there is a question regarding DeNoise AI:

https://help.topazlabs.com/hc/en-us/articles/360026224352-DeNoise-AI-Frequently-Asked-Questions

11.) What is the difference between DeNoise AI and AI Clear?

DeNoise AI is much more powerful than AI Clear at reducing noise and includes completely new processing models. These processing models are better trained for noise removal and retaining image detail. AI Clear is only accessible as a Studio adjustment, whereas DeNoise AI can be accessed as a standalone or a plug-in for your host editor.
looks like topaz is saying DeNoise AI is their best NR product for now

better than AI Clear
 
You can't argue with a free upgrade, especially when you get to keep the old plugin as well. Less controls but it does a fair job out of the box. Not sure about the sharpening. Makes a mess of the signs in my example, but it did a pretty good job on some branches against a sky (not shown).

I got Topaz AI NR as a free upgrade, so I figured it might be fun to play with. Actually, it is not fun at all, because of extremely slow operation, at least on my MacPro (late 2013) with 32Gb RAM. The results look good, but there is no way that I would use this glacial software when I can use DxO PRIME. PRIME does slow the final output process, but that is far better than having to wait for the Topaz program to render every single adjustment and then waiting what seems like an eternity for the final output.
 
Weird .... it isn't slow at all on my 2013 27" iMac - 24 G Ram, 2 G VRAM.

Now, Sharpen AI is sloooooow........
 
AI, in general, and these tools in particular, take bazillions of GPU calculations. A 2013 Macbook GPU may not be up to the task. It is time-consuming on my generic Intel GPU, but it's manageable.

Likewise, serial modems seemed fast at one point...until you started shoving truck-loads of data through them. It's all relative.

BTW, the OP is referring to AI-Clear which is much less computationally intensive, and therefore less time consuming, than AI-DeNoise (released yesterday).

Personally, I cannot see why anyone would choose to subject himself to the pain of using AI NR when DxO PRIME is so freaking good. In addition, DxO Photolab 2 (where PRIME lives) is a very solid raw converter, so for those files that require serious noise reduction, just use DxO both for raw conversion and NR. OTOH, for those who enjoy pain.... ;-)

I have DxO Prime, and DeNoise AI and AI Clear. I am not having any pain. Additionally, I find DeNoise AI is taking less time than DxO Prime.

Running Topaz AI-NR has induced no pain for me. I have a fast machine, and AI-NR is running fine for me.

I already own the older DeNoise, so this came along at no cost.

As for a raw converter, I use LR & Capture One. I have no need for a 3rd. I shoot raw mostly at lower ISOs with a Canon 80D, and LR handles most of the noise well. If not, Noiseware or topaz Denoise has worked fine. CO does ok, but it is not made for midrange ISOs.

On some very high ISO (8000 & 16000) shots I have tested AI-NR and it has done an excellent job; better than the older deNoise. I have more testing to do. But right now, I would use it on the few good shots that would really need it.

Perhaps you are using the default settings and not making any adjustments on your own, because those adjustments do take time. Also, I have found the final output from AI NR is much slower than from DxO with PRIME on my computer.
 
Well, I am glad that the program is running speedily for some users. For me, it is a tortoise. Regarding DxO PRIME, I have always thought that NR is best done very early in the editing process. PRIME works on raw files. Are you using AI NR with raw files or with converted jpegs or tiffs?

I am running it on a machine designed for LR and PS. Those packages fly.
For me, it is a tortoise.
I have only timed it once, but it seems to be the same for multiple runs.

These are the results for a 24 mpixel raw opened by PS, then AI-NR applied:

It takes 2 1/2 secs to do a preview at 100%, and 33 sec to process the whole image.
Regarding DxO PRIME, I have always thought that NR is best done very early in the editing process.
I tend to agree in principle. But with both LR and CO I don't know the order they process in. When I play with an image in PS where I can control the order after I use Camera Raw, it seems to make little if any detectable difference before of after tonal adjustments.
PRIME works on raw files. Are you using AI NR with raw files or with converted jpegs or tiffs?
I only shoot in raw, and I have only tested raws and tiffs so far. My only jpegs are finished photos, generally to share on the web.

I am not too hung up on detailed systematic tests, as the preliminary results look real good. But I have tested a couple of raws directly into AI-NR and output dngs. I have also tested AI-NR called from LR, which sends it a tiff, and I have tested it directly in PS from both a raw and a tiff sent from LR - which is consistent with my current workflow. I have opened up the dngs in both LR & CO.

AI-NR seems to be much better that the older deNoise on very high ISO shots with people in poor light. Some of the other shots have been good, but I have not made comparisons yet. My sense is that is about the same on some shots, better on others.

No, I make separate adjustments every time.

What I have done so far is to start with Lightroom, and let Lightroom call DeNoise AI with a TIFF file.

So there's little chance that someone on this thread will have the same computer, OS, and be processing the same RAW file generated by the same camera.

Hence the acronym YMMV.

I have Denoise 5, got a free upgrade to 6, and to AI. Since I'm doing a project on architecture I occasionally have to deal with street signs. AI really messed this one up. In fact D-6 combined with Infocus yields a much better result.

Here's a better result from AI.

I didn't consider the time to render to be excessive, nor do I own DxO so I can't evaluate PRIME. My experience with it, maybe 3 years ago, was that it was really slow.

Again, YMMV.
 
AI-NR seems to be much better that the older deNoise on very high ISO shots with people in poor light. Some of the other shots have been good, but I have not made comparisons yet. My sense is that is about the same on some shots, better on others.
The way I see it is that AI clear tackles light to medium noise very well, Denoise Ai was targeted towards medium/heavy noise and Sharpen Ai is targeted towards removing blur...

So, if you want the best out of images, use clear AI and Denoise AI in conjunction with eachother.

Some people's personal tests show that Denoise Ai is better at high iso images then dxo prime, wich tackles light to medium noise very well.

I am not sure that it is messing up text. A an example, here is a shot taken in front of the LA Zoo. I used an Olympus EM5ii with the 12-40mm f2.8 Pro lens. This was taken at 12mm.

Here is a blow up of the sign in the middle taken from the original RAW:

And here is the same blow up using AI Clear:

And here is the same blow up using DeNoise AI

a87244f540804fda9c36650f1ff54160.jpg

Here is a slightly larger version of the DeNoise AI image. Understand that this is really pushing the image and the finer print is not readable due to the fact that there just aren't enough pixels per letter to make out what the letters are. But there is no smearing of the text.

One thing I do notice, is that the AI Clear does seem to be the sharpest. Maybe if I played more with the DeNoise AI results I could match it. But AI Clear was basically a one click solution.

I use Denoise AI on some shots of a performer in low light stage light (changing colored LED's) all shot at the same ISO of 6400 on a E-M!X and 75 1.8



7df741718c5d4ec1884c370b2ed9434c.jpg



.

Results were very good. Since all images were close to the same I wanted to batch process which is not available. By putting the selects in a separate folder and running from PS File->Scripts->Image Processor an action that created a new layer and then called Denoise AI, set some parameters, and then closed, I was able to batch. The action is simple and easy to create,

What I found surprised me. On a couple of images there where areas that were not denoised. This was a high contrast edge against smooth out of focus background with no detail. There were several other areas of highlight, mostly specular, that also were not processed. They were easy to fix using a low Gaussian blur on the selected regions, but still a time killer.

What was strange is that most of the other shots, often the next one that was taken a minute latter, were fine. Most of the shots were processed fine.

On the shots without the artifacts the results were outstanding.

This is a new program and does not have the refinements of most Topaz programs. No presets and the setting are not sticky. This will all come with upgrades as well as improvements the algorithm that should fix the areas that are not processed.

Image is one of the good ones. I like the grit and realism that grain gives skin. So I masked the denoised layer and reduced the denoising in the skin ares to show more grain - to taste. On the bad images the area at the bottom of the image over his right shoulder was the are effected. It is fine here.

I like how it came out. I have one image of an "old cowboy" like this that also came out well. I am finding that deNoise AI is doing well on faces in poor light.

I have also experienced DeNoise AI missing some areas. Don't know if this is still a bug that they need to work out. Tended to be where a dark shadow was in the background.
