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.

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!
Manu

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 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.

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?

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 in Aperture

Does anyone successfully use the Aperture Noise Reduction tool, or are you all using third party apps?
Paul

I use it for moderate noise, but for shots at a very high ISO (1600), I use Noise Ninja. There is a Noise Ninja plug in on the way for Aperture, which will be most welcome.

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.

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...

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.

Missing Sharpen and Noise Reduction palettes

I've just exported some pictures for the web from Lightroom 5 which had to be downsized considerably. I now find that the sharpening and noise reduction palette has disappeared entirely from the right hand tools panel. What's going on? I've tried quitting and re-opening Lightroom and also shutting down and restarting my computer. (Macbook Pro retina and Mountain Lion)

If you are talking about the Panel in Develop, right click on any panel header and make sure that Detail is checked.

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 visible only in Develop area.

My Lightroom 5.4 for mac has a bug in noise reduction. The noise reduction is visible only in the develop area, and while switching to library it disappear. This affects also exported files and published files like flicker's one. I work with raw files taken with my nikon D5100. Is there any way to fix this bug?

Are you viewing these at 1:1 / 100% Zoom or smaller? Can we see screenshots of what you’re seeing at 1:1 zoom? Are you apply Export sharpening? Are you resizing smaller? Flickr does add its own sharpening, I believe.

Sharpening, noise reduction and blurring (general)

Sharpening, noise reduction and blurring ...
I need to read an extensive and up-to-date reference about these topics in digital imaging.
I would like to learn your book advises ...
Thanks a lot.
PS. It can be technical.

Thanks Jeffrey,
I want to learn all the sharpening algorithms in the digital imaging world today (and also for NR and blurring, as they are closely related subjects with each other).
Indeed, I'm trying to understand the PS and LR tools.
And, in order to understand their tools completely,
I think I should have a solid background on these subjects ...
For example ...
I could not understand yet how the detail slider works in LR.
It is said that it uses deconvolution algorithm ... but if you ask me it looks like a smart sharpen applied to the high frequency.
Is smart sharpen deconvolution?
Looks like ... but I don't know.
Like this ...
Of course, I can use them without knowing them so much,
Just "need for knowledge"
I read Jeff's book, but I think I need more.

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.
Dropbox - example.tiff
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.
