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!

Noise reduction doesn't work?

Hi All,
New user here (testing the demo). I have a moderately loud
air conditioner system, and as a result there is a constant hum.
I'm trying to get the noise reduction to work, but to no avail.
Here's what I do.
I record a clip. then select Edit Timing. Then Adjust Volume.
Then check "Dynamics (boost quiet sections), then I play with the
Noise Threshold and Ratio sliders (primarily Noise Threshold).
These don't seem to do anything, though I *can* adjust the volume
of the clip successfully.
What am I doing wrong here? Thanks!

Hi carloshl
Welcome to the world of Captivate!
Seriously, the audio editing bundled inside Captivate is
always reported as being rather anemic. I compare it to the jack in
the trunk of a new car. Enough to change the tire once in a while,
but if I'm gonna do it more often than that, I should probably
invest in a different tool.
The really super good news here is that your investment need
not be cash! There is a wonderful and totally free audio editor out
there called Audacity. You may download it by
clicking this magickal
link.
Oh, and you should probably also find a quieter room to
record in.
Any possibility of turning off the air for a brief
period?
Cheers... Rick

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.

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.

The two are virtually the same, as far as I can tell.
It looks like the 1:1 issue in Develop view biting me again... If you view the image in develop view in less thatn 1:1 it looks great.

If I export th CR2 to JPG then Import the JPG then appy NR to the JPG and export, I get the results im after.... there's got to be a better way?

De-noise on iPhoto not working with Canon camera pictures

When I try to use the de-noise option in iPhoto on some pictures taken with a professional camera (Canon), it does not de-noise the picture.
I tried diffrent stuff to see what works and what does not:
- If I use a picture taken from iPhone / iPad, in iPhoto de-noise works
- If I take a professional picture, send it to my iPhone and resend it on my Mac, the de-noise will work
- If I use a professional picture on my Mac desktop, de-noise works as well.
Just not in that initial circumstance ... Strange !! Help ?!

How does this
When I try to use the de-noise option in iPhoto on some pictures taken with a professional camera (Canon), it does not de-noise the picture
differ from this?
- If I use a professional picture on my Mac desktop, de-noise works as well.

Noise Threshold - Normalize not working?

I can't get the Noise Threshold or the Normalize to work at
all. I can set them to 100% or 0% or anything between and nothing
at all happens to the audio.
What am I doing wrong?

Hi Lori! Great to see you again!!
Yep, it has always amazed me the number of folks who pound
the keys over and over when they have a problem, and an hour or two
later, just as they finish their second cup of coffee, the problem
goes away (
perhaps because they also chose that time to reboot the
machine?)
. . . so they declare that finishing your 2nd cup of coffee
will fix the problem. Gotta love the logic.

Noise Reduction on slideshow or image export

Hello, does any one know why the Noise Reduction does not work when creating a slideshow or exporting the image ? It simply ignores my noise reduction settings.

Which version of Lightroom are you using.

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.

Red Eye reduction not working

Iphoto 11
Red eye reduction does not work, auto is not selectable and circling eye and clikcingh does do anything.
I have trashed the plist file, repaired permissions and rebuilt the iphoto database. Nothing fixed the problem.
ANy other ideas I can try ?
all software updates applied , 10.7.3

As a Test:
Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?

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 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.

PV2010 Color Noise Reduction Robs Dark Tones

No pun intended.
I thought at first it was the raw-conversion/de-mosaicing, but its turned out to be the color noise reduction.
Here is a the latest example of a picture that looks better in PV2003 than PV2010 no matter what I do, because of loss of clarity / contrast / dark-tones resulting from the new Color Noise Reduction algorithm. Note: This loss can not be restored using clarity or contrast sliders.
This probably ought to be a feature request: A slider that controls the coarser aspects of color noise reduction (color waves or clarity/contrast) versus the most localized aspects (color specs). In this instance, just getting rid of the specs without trying to reduce the waves might leave the dark tones(?) - Something like that. In any case, there is room to improve color noise reduction so that it leaves the dark tones / contrast / clarity in certain cases like this.
(Its a 100% crop of a section of a fish under water)
PV2003:
PV2010:
The difference is striking when viewing the whole photo from afar...
PS - I just discovered that minimizing noise reduction will maintain the dark tones better - I've therefore added down-throttling of color noise reduction to my PV2003 -> PV2010 practice.

Luminosity Contrast slider also helps maintain some darker tones.
Indeed it do.
And, last but maybe (or maybe not) least, one can cheat a bit at the end and add some grain, to give the illusion of greater detail / texture. So, if you really want to preserve full detail when converting high ISO shots from PV2003 to PV2010, you need to:
1. Crank up the luminance noise reduction detail slider pretty darn high (if not all the way up).
2. Crank up the luminance noise reduction contrast slider pretty darn high (if not all the way up).
3. Minimize color noise reduction amount.
4. Crank up the color noise reduction detail slider fairly darn high (not all the way up! - color artefacts - bleh).
5. Maybe add a touch of grain (pretty darn low).
(I've left out the luminance NR amount slider and sharpening because they are the more obvious ones).
I'm guessing I'm not the first person to fall into the trap of trying to recover detail lost by noise reduction by decreasing luminance noise reduction amount and increasing sharpening detail (and maybe amount too), and winding up right back where you started - too much noise. The detail/contrast sliders of the noise reduction controls really work a lot better for that, and minimizing color noise reduction is also a hot tip for you detail junkies.
I hope I'm not the last person on this forum to realize what is now seeming sort of obvious to me, whilst everyone has a good laugh...
(I had previous just left color noise reduction and detail, plus luminance NR contrast at their defaults (I discovered the importance of the lum.NR detail slider long ago...) - but not anymore. It has helped me to articulate all this - hope it helps somebody else too..........

Can Long Exposure Noise Reduction be turned off ICLE5000L

So as above. Can it be truned off.I'm taking my own dark frames and using a PC to subtract them. Having to wait an HOUR for the camera to be able to take another shot after a 30 min exposure is down right irritating! It says on the Tech Spec, it is available. Not mandatory.

This Sony support page says "Long Exposure noise reduction is not performed with the following functions." Continuous Adv.Speed Priority Cont.Bracket: Cont.Intelligent AutoHand-held Night Shot in Scene SelectionAnti Motion BlurSweep Panorama I haven't tried but hoping one of the above will work for you.

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.

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.
