Noise reduction issue

Is anyone having issues with exporting the noise reduction adjustments from Lightroom 3?
After I make the changes and export a new jpg file I notice that the image does not appear
as it does in Lightroom development stage. I also noticed that the image looks different
in the library and develope modes. Not sure what I am missing here or do I just need new
contact lenses

There is a fair amount of discussion about this and I find it a bit of a pain as well, particilarly when dealing with very high ISO images - I find my self having to go back and forth to the Library module to see the effect overall on the image. So, but as best I can tell:
1.     The Develop module in 3.3 does not show effects of NR unless it is zoomed significantly, probably around 1:1 or higher.
2.     The Library previews are generated after development changes are made/finalized and thus have NR included though maybe just a very good approximation.
3.     Some have requested an option to show NR effects in Develop module regardless of the zoom level (which I think was the default for a while in at least one version of LR3).
4.     The reason for the current feature is primarily to improve performance in the Develop module, particularly when the visual effect of NR is sometimes very difficult to see at anything less than 1:1 zoom.
I am on the list of those hoping for the option to show NR at any zoom level. If the hit to performance is too great we can always then opt to turn it off.
Hope this helps.

Noise reduction issue LR 3.6

Hi,
After reducing noise in an enlarged image, said reduction is no longer visible when going back to full view mode in LR 3.6. Does anyone know how to solve this?

By "enlarged image" do you mean 100% view?
If so, this is by design - except on high ISO images, the effect of NR can only be seen at 100% view. It's partly a resource thing, and partly because - the logic goes - noise in low ISO images can only really be seen at 100% anyway.

Noise Reduction output Issue

Every time I apply noise reduction in LR3 Beta 2 the adjustments appear in the preview window in LR but as soon as I export as jpeg the processing dissapear. It only happens with noise reduction - all other processing stays on the image. Any Help?

I do notice a difference between the image quality in the Library vs. Develop and noticed that shortly after i had posted the most recent response. I am just a little confused by your post when you say that the effects are only displayed on a 1:1 or higher scale. When i apply any form of NR the previewer - even at FIT - still shows adjustments happening. Is it simply rendering what it thinks may be adjusting or can it not comprehend the larger scale so it just smooths out some details?
And even at that, if i am able to achieve a desired effect in the previewer of Develop - shouldn't Lightroom be able to export that image that is it showing me? I am confident that i am able to reproduce the desired look in photoshop - basically through some smoothing - but the ability to create that in LR would save a lot of time.
I digress i am not very confident in my use of Lightroom as i have only been using it for a brief time - switching primarily from aperture i find lightroom a lot easier and more efficent.

Missing noise reduction feature in iMac 2012, Do you all know if that feature was available in previous iMacs??

I have been having some issues in my iMac 2012, with the noise reduction feature. I have a MBP retina display that in system preferences has the noise reduction feature. However, in the new iMac 2012, I don't see that feature. Plus, I have been having issues with facetime, people that I call are telling me that they hear feedback whenever I talk to them. Does any of you know if the new iMac is supposed to have the noise reduction feature?

I was trying to find the "use ambient noise reduction" option in my new iMac, but in the new iMac I don't have that option. I was wondering if in previous iMacs versions had the "use ambient noise reduction" option available because I have an issue with facetime, people that I am calling are telling me that they hear feedback or static sound and they can't hear me well. I believe that with the "noise reduction" option, that problem will be solved. However, in my iMac, I don't have that option only in my MacBook pro. The reason that I am asking if in previous iMacs versions had that option is because I believe that there might be a bug that Apple needs to fix in order to have that option available in iMac.

Audition CS6 crashes while running Adaptive Noise Reduction

Hi everyone!
So that is the problem, I edit an audio file, run Adaptive Noise Reduction filter, and somewhere during the processing the computer just crashes. Sometimes it happens and sometimes not. I saw that computer showes up an alert message just before the crash but I wasn't fast enough to read what was written there. Recently I did a clean system install and have just some programs installed. Before system reinstall the problem was not there, although the program (audition) is exactly the same. What to do?

I run the pro version, but it's basically the same. I've got all the updates installed, but I haven't noticed it slow down at all. Mind you, this is a fast system anyway. But if it's crashing, then installing updates won't fix that; you need a fresh reinstall on an absolutely clean disc first. Okay, that's a pain - but look on the bright side; you aren't running Windows 8. Recently I wasted nearly a day of my life on that, and I'll never get it back. The basic rule about M$ OS's hasn't changed - it's only the odd-numbered ones that are worth bothering with, as a rule. And none of them are worth installing until the first service pack is issued.

Rauschen - Noise reduction - Denoise

I need to reduce noise on my photos, but it does not work with PS Touch even if the option is there! I have moved the slider from 0 to 100. It tried with another app that is adobe ps express, and it worked well.

I have the same exact issue!
I've tried re-installing and rebooting the phone. I literally bought the app to make my skin look sexy and smooth with the noise-reduction! But it's not working! Please help my skin look good!

In-camera high ISO noise reduction & ACR

I've been involved in a discussion over on DPReview where someone believes that, when shooting with a Nikon dSLR (in this case a D7000, but the model isn't really important) high ISO NR is automatically applied in-camera directly to the raw file, and this will be carried over to any raw conversion software, including third-party software such as ACR/LR.
Now I do agree that even with NR switched off, Nikon do automatically apply some limited NR to high ISO images in-camera, but I'm pretty much 100% certain that this is not something that ACR would interpret, and so it would not actually have any effect on the appearance of the raw file when it's processed. In fact, if the high ISO NR is somehow embedded into the raw file, that would go against my whole concept of how a raw file works in a convertor such as ACR! Surely any "default" high ISO NR is just added to the proprietry part of the EXIF, and is therefore only factored in when using Nikon conversion software (ViewNX, etc)? Otherwise, the file could not truly be considered to be 'raw'.
I think I'm right, but wanted confirmation from some of the experts on here! And of course, I'm also quite happy to be proven wrong!

What camera do YOU have, Molly?

Hi Noel,
Wow, I'm impressed with your efforts here! Your point about blurring being a potential sign of whether or not NR has been applied to the high ISO raw files is a good one, and I agree that, based on that thinking, the examples you've found don't really seem to show much evidence of that, particularly the shots of the focus/resolution target.
I do have a D7000; I replied as such back in post three ("yes I do" in response to your question "do you have such a camera?"), but I can see how that may not have been as clear as it should have been! I'm going to try some test shots myself to see if I can pick out any evidence of softening/blurring that may indicate NR being applied during the processing of the raw data. However, unfortunately my PC is currently being fixed as I've been having some hardware issues, so that testing won't be happening until I get it back (hoping within a week, missing it already).
Regarding your reference that indicates that high ISO NR can be switched off, yes it can, but apparently only up to a point - here's what it states in the Nikon manual (and what has in turn sparked off this discussion over on DPR):
"High ISO NR - option: off - Noise reduction is only performed at ISO sensitivities of ISO 1600 and higher. The amount of noise reduction is less than the amount performed when low is selected for High ISO NR" (as the article indicates, there are three options apart from off: high, normal, and low).
As I've said previously, my understanding was that all of that had zero bearing on the raw file once it was loaded into ACR: regardless of any NR settings applied in-camera, either by the user or by Nikon bypassing the user, they were all thrown away by the Adobe raw processing algorithms, as are things like picture controls, sharpening, contrast, etc. But following my recent discussion, I started to wonder if my understanding of the raw capture process was incorrect, hence this thread.
Thanks again for your work here. Above and beyond the call of duty!

Any chance Photoshop itself will get Camera Raw's noise reduction and sharpening?

I would love to have the noise reduction and sharpening from ACR 6 in Photoshop itself for JPEG, TIFF, and PSD files. Yes, I know I can open those files in ACR, apply noise reduction and sharpening, and then have it then open the files to Photoshop. But it would be so nice if we could do that without having to go through Camera Raw.

Matt Howell wrote:
Yes, I am absolutely saying that the noise reduction and sharpening of ACR 6 is vastly superior to any filters in Photoshop CS5.
For those who only work only with RAW files this is a non-issue, but I sometimes prefer to use TIFF files generated by CANON DPP software or occasionally even JPEG's straight out of Canon DSLR's. Going through ACR just for noise reduction causes unnecessary color space conversions, as well as just a needlessly complex workflow.
Perhaps you should ask Canon to make DPP noise reduction better. I also do not think is a good idea to get too aggressive with noise reduction and sharpening when you first bring a image into Photoshop unless you only use the image single use for a particular output device. Your better off working with a somewhat soft image till you ready for output and then sharpen for the output devive being used. If you use strong sharpening and NR up front sharpeing again for your output device may produce unwanted sharpening and NR artifacts... There are several third party noise reduction and sharpening plug-ins that are better then Adobe Photoshop built in ones. Noise reduction has to be balanced too much will loose detail masking detail is important. ACR noise reduction provides masking adjustments and works well. Third party plug-ins offer offer advanced masking features also. Photoshop noise reduction filter has a basic preserve detail slider which I presumes does some kind of masking but this is not as good at ACR masking and third paty masking. You can of course add you own masking before using photoshop noise reduction filter. Sharpening also needs masking for sarpening will sharpen noise as well as detail.
IMO your better off with third party plug-ins that are designed to be the best. They keep getting better there is no clear winner for all images. I'm been satisfied with NeatImage and I have only had to pay for two upgrades. I had to pay for the addition the 32 bit plugin then and for the addition a 64 bit plugin. All other updates to NeatImage has been free of charge even the lates version 7 of the 64 bit plugin was no charge for me.

Noise reduction not working on Lightroom 5.4 MAC

I have experienced that the noise reduction that I apply to my pictures is only visible in the develop area of the software. As I switch to library it disappear and the same happen if I export the picture in any kind of format.
I post a screenshot where you can see a sample picture with the desired noise reduction applied (on the right) and the same picture as it shows in the library area (on the left). Switching between this two areas (library and develop) results like a noise reduction toggle.

Is there a way to solve this bug?
Thank you.

Usually Develop-Fit view is crispier than Library or Export, when there has been enough noise-reduction added to an image to make it seem smooth, and people complain that sharpening is not being applied; however, in this situation through extreme noise-reduction settings, an artificial coarse texture has replaced the fine-grained noise which seems to manifest differently in Develop Fit view, and the complaint is that Library has no NR applied.
In more detail, there are two issues, here, both of the user's doing, not LR's:
1) A user-expectation that the Develop non-1:1 zoom is accurate regarding Detail settings. It is not. For years there has been an exclamation-point warning on the Detail settings section that says to view things only at 1:1. If a user doesn't see or ignores this warning then their expectation is wrong, as in this situation.
2) The Luminance Noise-Reduction Detail slider has been increased from the default of 50 to the maximum of 100. This has the effect of converting the fine-grain noise into a course angular texture, which is easily visible at reduced sizes except in the inaccurate Develop Fit view.
In the following side-by-side at 1:1 zoom, the lefthand panel is as per the user settings with the Lum-NR-Detail slider set to 100, while the righthand side has the Lum-NR-Detail slider set at the default of 50, with all other user settings remaining the same:
I would summarize what is occurring not as a bug but a different response of the inaccurate Develop-Fit rendering to a different coarseness of noise that is caused by an extreme setting of the Lum-NR-Detail slider. Since there is no resizing and no sharpening in the Export settings, I don't think the 1/3 bug has anything to do with anything.
It would be nice for the original poster (OP) to describe exactly what is wrong, after knowing that the Develop view is in accurate if not viewed at 1:1.

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!

Lightroom 5 no noise reduction on file export

Here are the steps I'm using:

Torsten,
Here's my favourite workaround. You could have done it too, and it's a simple, one-step solution:
Don't pay for software without thoroughly testing it yourself first.
If you've paid for Lr 5 before destruction-testing it and keeping a close eye on the forum (where this issue has been know about for ages), you've only yourself to blame.
Adobe will fix it when they're ready and able to: but it doesn't affect me in any "I paid for this, I expect it to work" way, because I won't be buying Lr 5 until it is fixed.
A really, really, really simple, inexpensive, trouble-free way to deal with all that stress...

Lightroom 3.6 DNG and Noise Reduction Problem

Hello,
I did a search and couldn't find this issue listed. I convert my Nikon D90 raw files to DNG. Never seem to have a problem with that except that the display(s) seldom shows the results of applying Noise Reduction (Color or Luminance). If my display is at Fit or Fill I don't see the results of what I am doing. If I zoom in to 1:1 or more, then I can see the results. All works fine if I am using a jpg file, it is just the DNG files that do this. If I want to see the entire picture with Noise Reduction applied I have to switch to the Library Module. Then when I go back to the Develop module the main display goes back to not showing the Noise Reduction, but the secondary display is ok until I apply another effect then boom, back to Noise Reduction not displaying. All of the other changes I make work just fine. It is just the Noise Reduction that causes the problem. This is really a killer when I am working on photos. This problem existsed before 3.6. Does anyone else have this problem? FYI - When I switch to the Library Module it takes a few seconds before the secondary display shows the photo with the Noise Reduction applied.
I have a quad core 2.4ghz with 8gig of ram and Windows 7 Pro 64bit OS. Plenty of CPU and memory available.
Thanks,
Harold

LR is designed this way to improve speed. I think it varies, somewhat, with how high the ISO is where higher ISOs show NR more.
I find this annoying, too, and which there was a setting to allow LR to compute the NR at lower resolutions if one chooses, instead of Adobe choosing things for us.

Noise reduction lost during export?

Hi everybody
I'm having a very strange issue in the last few days. I work on a picture and when I export it the noise reduction is gone in the generated jpg.
Please have a look at the screenshot... the image on the right is the image I see in lightroom... the one on the left is the jpg exported.
I'd glad is some could explain why is this. I shoot with a Sony a7.
Thanks.

There is nothing for Adobe to fix. They are not going to do a full export computation every time you tweak any slider—that would take seconds per slider move and there’d be a lot more complaints about how slow LR is than there are about people who wish LR was magic.
You’ll have to learn how to sharpen in LR, rather than assuming a Fit view is how things would look when exported at an arbitrary size.
Laura Shoe has a good review about the three phases of sharpening: Capture Sharpening, Creative Sharpening and Output Sharpening, where what you’re doing in Develop is only phase 1:

Noise reduction won't display properly in LR 3.4.1 Develop Module

I encountered this issue first time last night - noise reduction will not show in "Fit" view of the Develop module for pictures that have a graduated filter applied as well. Having said this,
- The pictures display correctly in Library Loupe view (Fit and 100%)
- The pictures display correctly in Develop module when zooming in to 100%
- The pictures display correctly in Develop module when clicking in history on Luminance smoothing (first picture). Selecting the next step in the history, Add Graduated Filter, displays the picture without noise reduction (second picture - I tried on a virtual copy the other way round - first have a graduated filter and then apply noise reduction, but doesn't work either. Noise reduction just won't display in Develop module / Fit View once a graduated filter is applied as well.
Has anyone else seen this behaviour or, even better, found a solution? I already tried purging the raw cache, no success. Working on Windows 7 / 64bit.
Thanks,
Andreas

Jeff, I had difficulty understanding this same issue as presented at the link I posted above. With my low-noise Canon DSLR RAW images I simply couldn't see the onscreen rendering issues they were talking about. It even appeared this might be unique to Mac platforms and Windows 32 bit OS, since my Windows 7 64bit system didn't appear to have this issue.
Following suggestions to shoot a picture at -4 F stops and then increase exposure by +4 F stops in LR helped me get a better understanding:
http://forums.adobe.com/message/3857767#3857767
Granted this is an extreme shooting situation, but it helps demonstrate what happens when using exposure, fill and HSL sliders to increase exposure significantly (+2 to +4 EV) in specific areas of the image. Now you have noise that will be visible in smaller exported scaled images, perhaps even those sized for posting to the web.
The issue is at lower ISO settings (camera specific), view sizes less than 1:1 have no noise reduction applied (Mac & Windows) or sharpening applied (Mac & Windows 32). There appear to be platform differences in the way sharpening is applied, because on my Windows 7 64bit system sharpening is applied at all ISO and all view sizes including "fit" view, but noise reduction is only applied at higher ISO settings – the same as all others have described. I wanted to point this out since it is one of the reason I had difficulty duplicating what the OP was seeing.
We know sharpness and noise reduction settings interact with each other, so it is important to have both applied in the onscreen image to determine their affect. Using images with additive Exposure, Fill and HSL slider settings approaching +2 to +4 EV, there is simply no way to see accurate rendering without both noise reduction and sharpness applied at all view sizes, including “fit” view. This can occur with low ISO images, not just at some predetermined camera specific high ISO where noise becomes predominant.

Noise reduction makes robotic voice

I have been using Noise Reduction feature on "Audition" with no problems. When I have upgraded to "Adobe Soundbooth" I have an issue with this feature. When I turn it on I hear robotic echo of the voice no matter what the parameters are, even if the slider of parameters is on the 0 point (no noise reduction at all). Furthermore, it makes no difference if I am doing it with noise reduction profile or not.

I tried using noise reduction for old recordings namely background hiss...then I discovered the audio effects work better for this...called "remove hiss" and also in the simple effects "Parametric" called "Under a blanket"
