Noise Reduction tool not effective

Hard as I try, I can't see any effect in using the Noise Reduction tool. I've tried it on photos from both compact cameras, as JPGs, and also Raw images from my DSLR. I've tried some images with visible digital noise (low light, long exposure shots), but whatever I do with the sliders, it makes no visible difference to the noise level.
Am I missing a trick, or does this tool just not work very well?
Cheers.

I just tried that, but switching the tool off and on made no difference here. I did find I could type a larger number into the 'Radius' box, which takes it up to 4.00 (it goes to 2.00 on the slider). That did make a visible difference, although it just made the entire image blurry. Adjusting the edge detail only beings out the noise again.
It appears to me that this adjuster is not much more than a simple Gaussian blur with some sharpening. The effects are similar at least. Indeed, I just tried adjusting the same image in Graphic Converter (from a fresh Raw file copy), and it is very similar to using a straight Gaussian blur (radius 4 did the job in GC too), and then apply some sharpening.
The only time I've found Gaussian blur to work well is if you can switch into Lab colour mode, and apply the blur to the different channels.

Are there any other enhancements in noise reduction tools in CS6

Are there any other enhancements in the noise reduction tools besides the improvement mentioned of the spot healing brush. Are there improvements on the click and pop removal tool and the noise reduction in the spectral editing view. Quite anxious to know...

Paul:
Welcome to the Apple Discussions. There is a hidden feature for changing the Redeye and Retouch tool size:
How to Change the Size of the Retouch and Red-Eye Removal Tool
Type Caps lockControl9
Undo caps lock
Click on the Retouch or Red-Eye Removal tool
The tab key will toggle between cursor types, a cross or a circle
The "[" and "]" keys decrease or increase the size accordingly.
NOTE: Using the "{" "}" keys will will change the value next to the circle and that represents the degree of change or intensity that the tool imparts on each pass.
Also check out the tip at the end of my signature for backing up the library database file on a frequent basis.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application, iPhoto dB file backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Noise reduction - RAW fine tuning and the Noise Reduction tool

Hi,
1- If I get it right, Aperture's RAW fine tuning "Automatic noise compensation" (translated from French) option uses the camera's information to adjust the noise. Is that correct?
2- The Noise Reduction tool is there to provide additional noise reduction, but this makes you lose some details. Is that correct?
3- How do you use them? I often find the Noise Reduction tool a bit overkill, but that's me.
4- This one is just out of curiosity. How does A3 compare to LR3 beta for you in that regard? In my testing, LR3 did a slightly better job (but A3 totally beats the crap out of LR2 for noise). BUT I have an old D50, and newer cameras handle noise better (especially Nikon), so does it really make a difference for a 2008 or newer camera?
Thanks!

I wonder if it's due to the type of files (Canon 7D). Do you still have those 7D files I sent you? Does the checkbox appear in Raw Fine Tuning for you with them?
I noticed this option in the manual the other day, but forgot about it until now.
True, it doesn't have the checkbox with the 7D files. However, it as a slider "noise suppression" (again translated) in the RAW fine tuning options (and still has the Noise suppression brick).
If you don't have this one too, have you reprocessed your images with Aperture 3? Since it has a new raw engine, it may be the cause of it.
I find it strange that Apple didn't tout the new RAW engine on Aperture 3 new feature, it clearly is an improvement over Digital Camera RAW 2, especially in noise suppression.
I agree the built-in noise suppression is much better than A2, but IMHO it pales in comparison with the Noise Ninja plugin from Picturecode. The key is that you calibrate a profile for Noise Ninja by shooting a color chart full screen on your computer at varying iso settings with each of your cameras. You then feed the images back in to Aperture, and tell Noise Ninja to create a noise profile for each setting. The results are amazingly good.
Now with a lot of new cameras, noise processing is getting less important because the high iso performance is so good....but this is what makes Noise Ninja special...even when the noise adjustment is subtle, because it is working from a profile created with your camera, at the iso the shot was made at, its effects are seamless. They just announced a 64 bit plugin for Aperture 3, so no bouncing into 32 like other plugins at the moment...
Sincerely,

Noise Reduction tool

What exactly happens while adjusting the options in Noise Reduction tool? I can hardly see any difference in the video. I would like to know Why is it used and what is the result?

Noise Reduction Tool Disappeared

Hi,
I'm using the LR 5 Beta and I'm new to Lightroom in general. I was editing some photos last night and was able to use the "Noise Reduction" and "Sharpen" tools just fine, but this morning when I went to edit the same photos (and subsequent photos) those tools seem to have disappeared completely. I feel like I'm taking crazy pills.
Can anyone help me figure out what's going on?
Additional info:
I'm shooting in RAW and I've tried opening the original file as well as several other out of camera files and nothing is showing up.

Right-click any panel header on the right panel in develop (Basic, say) and check the Detail panel to get that panel back.

Export of noise reduction does not look like Develop preview

Hi,
I have a photo that has noise reduction applied, however, after export, it looks as if NO noise reduction has been applied. Other photos look like they have the noise reduction applied. Not sure why this one would refuse to export the noise reduction filter. In the Develop preview, it looks great, no noise. After export, noise.
Different but possibly related, On all photos, I noticed that the noise reduction preview in Develop doesn't update unless I zoom-in/zoom-out, then it updates it. But if I make any adjustments to the slider it doesn't update until I zoom-in/zoom-out again. This seems like a bug.

Noise Reduction is not working

I just upgraded from LR 2 to LR 3 and for some reason I'm only able to move the 'luminence' and 'color' sliders.' Why aren't the 'detail' and 'contrast' 'sliders' activated?
Thanks!

In the menus: Settings->Process. Or click the (!) icon in the lower right corner of image area.

Noise reduction / adjust amplitude not available for mono tracks.

Hi,
If there is a better group or forum for the following questions, please let me know.
I am presently performing the sound editing and mix for a feature using version 3.0.1 of Soundtrack Pro. Though I am mixing using the surround feature, I have chosen to only use the center channel for dialog, and the front right and left speakers for everything else.
Furthermore, the picture editor (who is in a different state) sent me mono dialog tracks (he first sent me location and ADR on the same stereo track, which I could not separate for elimination or proper levels) and stereo tracks for the effects and score. The two problems I am running into are:
1. I am unable to access the noise reduction tools for any of the mono tracks. The individual stereo tracks allow me to do this. What appears to be going on? Is there a workaround?
2. Similarly, I am unable to access "adjust amplitude" under the same circumstances. Again, the stereo tracks are fine.
Any assistance would be much appreciated!
Kind Regards,
Andre

No, although ACR v4.1 does apply some baseline noise reduction to many raw files, I do not think that it applies any default NR to TIF files. Lightroom v1.1 does not apply any noise-reduction to TIF or JPG files by default, at least as far as I've noticed, so I believe this will likely carry over to ACR v4.1 as well. Of course you *can* turn the NR sliders up from zero and then it will! In any case, you'd be advised to test that theory yourself just to make sure, before designing a workflow around that assumption...

LR4 Feature request: Add local noise reduction

Hello,
I wish to apply noise reduction localy. On the backgroud apply a lot of and in forgroud (where the object/personn ist) a little.
See this example.
The current local noise reduction ist NOT the same as the one in the detail panel. It is a lof f less efficient.
Thanks

I use negative sharpness combined with negative clarity and/or contrast for blur effects. It's not unusual that I stack multiple brushes when -100 isn't enough
Thanks for the tip. My problem with blurring in Lr is that the blurred region ends up "too clean" (the rest of the photo has at least a bit of noise in it). I have dealt with it in the past by applying grain to the blurred region using an external editor - but that takes a lot of the fun out of doing the blur in Lightroom.

Adjustment brush with exposure setting cancels noise reduction

Hello,
I just noticed the following problem:
1) Camera Raw 6.5; Bridge CS5 (4.0.5.11); Mac OS X 10.6.8; Mac Pro 3,1; Dual Quad-Core Xeon; 8GB RAM.
2) Start with a noisy raw file (mine is from a Canon 5D II).
3) Apply Noise Reduction (Luminance:30; Lum Detail:75; Lum Contrast:0; Color:25; Color Detail:50).
4) Go to Adjustment Brush and set a non-zero Exposure value.
5) Apply brush to image and notice the Noise Reduction effects disappear (noise returns).
6) Click Clear All button to clear Adjustment Brush and Noise Reduction works again.
This seems to only happen with Adjustment Brushes with a non-zero Exposure value (applying brightness or other settings don't seem to produce the problem).
Anyone else seeing this?
Thanks!

Richard (and others),
Yes, very good idea to check that. The problem does indeed get applied to the full sized, opened image as well as to the display previews. After working with this more, I now notice that I was wrong to say that the entire noise reduction is cancelled - rather it "changes", sometimes subtly, sometimes more dramatically depending on what the noise reduction settings are set to. Further, how dramatic the "changes" appear depend greatly on the preview zoom (the changes are more subtle at 100%, but it can look like the noise reduction is completely turned off at 50% and 66%).
Now I realize that the noise reduction does not ordinarily display at all preview sizes (especially smaller ones), but this is different. At preview sizes where it does normally get applied, applying an adjustment brush with any non-zero exposure value (even just +0.05) can have the appearance that the NR is completely turned off for the whole image. Simply nudging the exposure value back to zero brings all the noise reduction back.
Also, to be clearer and avoid confusion for others, the change in noise I'm seeing is not localized to just the brushed spot. Obviously if one increases exposure, you'd expect to potentially see more noise. Instead, what I'm seeing happens to the entire image, even if I simply paint a single small brush dot, say in a far corner. Having the image change globally in response to painting a small spot with the adjustment brush cannot be a correct result. Further, this does not happen with any of the other adjustment brush settings like brightness, contrast or saturation. There must be something unique about the exposure setting that perhaps introduces a new step into the processing pipeline, and this step is affecting the entire image.
In any case, the problem only seems to be an issue in somewhat extreme cases and is less noticeable at 100% (and the finally opened image). It's more just annoying when previews are generated for viewing in Bridge, for example.
I suppose one alternative might be to rob a bank and go buy one of those new 1D X's. Then maybe I wouldn't have to worry about noise anymore.
Thanks for the responses!

Noise reduction problems LR3.4

I have some problems with the noise reduction.
1. When watching photos in library mode the noise reduction is not working. Switching to development shows the correct image with nr removed.
2. When using the brush (reducing exposure on face) on an image the complete NR for this image isn't working. As soon when the brush is removed everything is fine!!!

Hi
You can't really do effective and selective (that's what you want) audio editing with FCP filters. But if you HAVE to, you can use the following filters (not sure if they are all in version 4.5):
Hum remover
compressor
equalizer (3band)
Sound editing is an art, and may take a while to get the best filter settings and combination. Good luck.

Noise reduction techniques

I took some action photos on a dark overcast day so I had to use high iso.
There is quite a bit of noise in my photos.
what is the best way to moderate the noise???? not sure how to use the noise reduction tools in LR
Is there a good plug in that will simplify noise reduction?
thanks for the discussion
diana

Diana-
In Develop Mode, zoom out to 1:1, and then go to the section for noise reduction. This is a subject about which books could be written ( and have!), but do use the sliders to bring it down till it starts to look off.... that'll probably print fine.

Background Traffic Noise Reduction

Hello all,
I'm currently editing my short film and I have huge issues with background traffic. I've faught with Adobe Audition for about 2 hours now and I can't get a good reduction on my background traffic. I've used adaptive noise reduction and Noise reduction (Process) and I just can't seem to get a decent reduction without having weird noises that would just make everything worse.
If you want you can listen to it for yourself, I'm linking it with dropbox.The beginning is the worst I have plenty of other audio that has more backgrounf traffic.
Thank you in advance for you help! Cheers!

I couldn't find a link to your Drop Box but I can make a few general comments.
First, traffic noise is going to be very difficult to work on because it's constantly changing. Noise reduction is most effective on things like electronic hiss or an air conditioner running continuously in the background.
However, to give yourself the best chance, use the Noise Reduction (Process) version. Grab a sample of the background noise but don't try to get rid of all the noise at once. Do a very light reduction, grab another noise sample, then do another light process. Keep this up until you hit the best compromise between background noise and the sort of artefacts you've noticed. Depending on exactly what the noise is, you may find that increasing the FFT size helps.
Because the background will be constantly changing, you MAY find you get better results by breaking it up into smaller chunks with more similar noise problems....general traffic is different from a passing bus.
Which leads me to a final suggestion...if certain noises are a fairly specific frequency, instead of using NR, you might try to go to spectral view and use the marquee tool to draw around the offending frequency and either just hit delete or maybe the spot healing tool. This'll only work with a narrow frequency band--I was once able to remove a passing ambulance siren almost totally using this method--but a passing truck rumbling through a wide range of frequencies wouldn't really work.
Finally, you might find that some subtle boost in the fundamental voice frequencies might help your intelligibility a bit. You'll have to play with frequencies to find the right ones but they'll be in the mids somewhere.

Noise Reduction for Premiere CC 2014

Before the new release, I have used Neat Video for noise reduction. Unfortunately, this plug-in is not working well with CC 2014. The only native plug-in I saw was to create noise, not reduce it. Does CC 2014 have a noise reduction tool?

The Mercury Engine can use OpenCL in Radeon cards. That being said, the R9 M290X is not in the list of currently supported cards, and therefore the Mercury Engine should default to Software Only.
Adobe won't add the R9 M290X to the list of supported cards until they can fully test it. So hopefully they will add it in a future update (*fingers crossed*).
Until then, you may be better off with a maxed out 27" iMac which has the GeForce GTX 775M, which is supported. It will no doubt perform better, and yes it will be like a hot knife through butter.

Noise Reduction is a PITA! Will this ever get easier?

One of the things (and there are many) that I like about LR is the
non-desctrcutive nature of the changes it makes. Recently I had a couple a
hundred shots where I had to use ISO 1600-3200. The LR noise reduction can
not hold a candle to the 3rd party tools. I use Noise Ninja myself. In order
to make sure that I had the best image to work from I had to export from LR
as a PSD in 16 bit and then run NN on the PSD file. The resultant PSD file
is 4 times larger than the DNG in LR. I now also have to deal with 2 files.
I remember reading about an SDK for LR that should allow NN and others to do
this in the same way that LR does its edits in a non destructive fashion.
Is there any progress on this front?
Does DxO 5 offer this?
The current way is really akward.

L. Little,
I haven't lost all hope that Adobe will get more into this. Raw Shooter Pro did not have near the issues with NR that LR has, had some nice pre-processing aspects for Noise (you can set up similar things under LR), and did not seem to create the issues frequently seen in LR especially with High ISO. Hopefully Adobe can pull more of that into the product. I think, from some of the readings on forums, that the whole NR engine in LR was a new redesign, maybe this is a case of "if it isn't broken, don't fix it" at play, with that comes a desire to make whatever the new design is work.. so I guess we'll have to see if the refinements keep coming. I don't think they can ignore all the complaints from people.
The possibility of 3rd party tools linked in from the folks at Noise Ninja, Neat Image, etc. is also something to look forward to. For high ISO images, I tend to let NR tools in CS3 handle the exported JPG after I've done any other adjustments, as opposed to sending it out via conversion, and bringing it back into LR.
