Adobe Denoise - nutz not to use it?


Recommended Posts

OK with all the talk of noise and denoisers in other threads but with a tendency to get sideline into other areas of discussion often irrelevant to the original post, I figured it might be time for a practical demo of what Adobe Denoise can actually do for high ISO images. It is actually remarkable in that it effectively removes noise while maintaining or enhancing sharpness on the main subject. You might call it a game changer in that images that would never have passed Alamy QC in the past, if they were to be examined by QC, could now easily float on through.

 

So I have just uploaded a set of nutty images to Dropbox which anyone interested is welcome to download and examine. These are full sized JPEGs at the highest quality from a 45MP Nikon camera shot at three different ISOs: 64, 800 and 12,800. There are two versions of each image. The first version is at my default Lightroom import settings, basically default Adobe sharpening and very light colour noise reduction 25-50-50 which I always apply but no luminance noise reduction or any other processing. The second version has been run through Adobe Denoise at its default settings. The images have plenty of bland areas where the effects of the noise reduction are very evident.

 

The really remarkable thing is how good the ISO 12,800 image is when Denoised. I would never have considered submitting anything from my 45MP Nikons above ISO 1600 or maybe 3200 max before but this would probably pass QC as it is and it definitely would if downsized a bit. 

 

Others have their favourite AI denoisers. I have only ever tried one of these and I was not at all satisified with the results. Given how good Adobe Denoise is and given that I subscribe to the Photography package anyway, I have no intention of investigating any of the other ones. However, if anyone would like to join in here with their own images and post links for downloading, please feel free to do so. There is no point in linking images from one's Alamy portfolio as these are too small to examine.

Don't mention it. If you have time to do something similar with a high MP Sony, it would be intersting to see.

That is nuts! How good the results are, can’t wait to get my new MacBook, this will resurrect older images I couldn’t denoise good enough. Thanks for sharing this, very helpful.

My Sony has a 42 megapixel sensor and is a bit old by now. It may well be the same sensor as the D850.

I have rented the 60 megapixel Sony bodies as well, but have not gone beyond 100 or 200 ISO.

I was thinking the opposite: small sensor / low resolution could be interesting. Jeffs RX10 my RX100. Early Nikon dslrs.

We probably all have files from the dawn of digital. (Hey if someone is looking for a good book title..)

Maybe even my Canon files with horrible noise in lifted shadows - that may be a bridge too far though.

And like read out banding, that seems impossible to fix. (I'm investigating Leica Monochrom at the moment.)

No worries. You definitely a need a decent computer to run Denoise but any of the M Macs should be fine. Edo has been using it on a first generation MacBook Air with 8GB of memory as far as I recall.

Most of my early Nikon DSLR images were shot on a tripod at low ISO as were my dawn of digital Canon 20D images. The latter were pretty horrible for noise at anything even approaching high ISO. I no longer have my RX100VA but I don't think I ever pushed it to the limits either. I think the big boon is for me is going forward, being able to shoot in relatively dark conditions, handheld with IBIS at much higher ISOs than I would ever have dreamed of before. 

 

So have you invested in a monochrome Leica or just investigating?

That’s good to know, I’m about to order the MacBook Pro 14 M3 and go for 24GB unified memory and a 1TB storage, then at sometime get an external monitor.

Sounds good. You will find it unbelievably powerful in comparison to a 2012 model. These Macs are amazing little machines. The XDR screens are made for for HDR stills and video editing.  If I was buying now though, I would try to stretch to 32GB for future proofing, which would mean going up to M3 Pro model, but it is quite a lot more expensive. That said you should get a lot of years before 24GB is not enough unless you start editing 8K video or the like.

Just investigating. The banding came up in the process, but was not part of the initial problem/question.

Students get a lifetime guarantee.  Most anyway. 😁

Excellent. Adobe Denoise has certainly done a much better job than my old copy of Topaz Denoise 2.4.2. I took the ISO 12800 default jpg image and applied Topaz to it. I played around with the settings but couldn’t get anything as consistent as Adobe’s Denoise. When an image is this noisy my Topaz 2.4.2 seems to flip between 2 extremes. In some areas of the image the noise is completely gone, but the detail is also lost leaving a smooth waxy type appearance. In other areas Topaz interprets the noise as real detail and replaces it with false looking “structure/texture”. Adobe Denoise shows a similar effect, but it’s much more subtle and well controlled. As you know I’m a fan of Topaz, but that’s largely because I find it useful for reducing film grain in digitised images of 35mm transparencies. For control of high ISO noise I use Adobe Denoise, even though it’s a bit slow on my 2017 iMac.

 

If you posted the RAW of the 12800 image, then maybe others could post results they get with their preferred denoise packages? It wold be interesting to see what DXO Prime makes of it, for example, as well as the latest Topaz.

What version of Photoshop are you using for this test is it beta?

Will sort some raws in due course.

I used the latest version of Lightroom (13.2) which is the same as ACR (16.2). I don't know if it has changed since the full version was released last April I think.

I've made some changes to the original upload - the raisins will become apparent on viewing. I've reshot and added ISO6400 and ISO25600 samples to the previous sets of ISO64, ISO800 and ISO12800. There is no difference in the conclusions: Denoise is amazing. The ISO25600 sample looks horrible befoew Denoising but becomes pretty acceptable especially if downsized. Because Denoise includes the Enhance function which seems to apply a very tasteful sharpening to the main subject while leaving the background alone, the loss of detail even at very high ISO is much less than one might expect. Anyway the new link is below and the previous one no longer works so I've removed it from the OP.

Should have said Topaz

 

I don't know if the Topaz denoiser can work on raw files. I used an early version about four years ago and it couldn't work on raws at that time.  Being able to denoise the raw file is of major importance in my opinion. That is a massive advantage of Adobe Denoise - it fits neatly in my workflow. I can do everything in Lightroom or ACR and finish in Photoshop if required. And it's fast. 

 

If you are an Adobe Photography Package subscriber, I'd recommend taking the Adobe Denoise for a test drive on a few high ISO images. The results are astonishing.

Many thanks, yes the Topaz Denoise 6 works on my raw files but would be interested to have a go at the Adobe Denoise though I don't use Lightroom, is there something else specific I need to download, sorry to be a pain😁

If you have the Adobe package which I presume you do, you can use Denoise from Adobe Camera Raw. It's exactly the same as using it in Lightroom.
