Lousy noise reduction

I find that the noise reduction in LR 3 has absolutely no effect whatsoever. Whenever I use it I see no change in the photo at all, as opposed to other products I have used, such as Corel Paintshop Pro, and Nikon Capture NX2, where you see the effect on the photo immediately. Has anybody else noticed this? It's not that my photos have a lot of noise to begin with, but when some noise is noticeable, I want it gone, and LR3 does not do it. I'm not sure if there is any difference between this version and the earlier one (LR 2), since this is the first time I am using Lightroom.

LR3b has noise-reduction so I'm not sure why you say there is none. It helps to be zoomed in to 100% to see what is actually happening with the noise and sharpening.
Using Process 2, the new LR3/ACR6 processing, noise-reduction only has a Color NR slider available in the beta and it works quite well. With Process 1, the older way, does both Luminance NR and Color NR and both work similar to the way LR 2 does.
You can switch between Process 1 and Process 2 on a per-photo basis using Settings / Process Version in LR3b.

Vocal Irregularity after applying Noise Reduction

In this new project I followed Bob Howes instruction:
‘Set the FFT size (on the advanced menu) to 2048 and grab a noise print from a gap of "silence". Select the entire filed and do reduction by 7 or 8 dB and 15%ish reduction. Set the FFT size to the next one up, get a new noise print and do another pass with the same low settings. Keep going, upping the FFT size each time.’
This new project I started out first with a Hard Limit. Then I followed Bob's advise with managing by steps the FFT size.
Sample One is a piece of the original.
Sample Two is the results of the effects.
It sounds as though the speed of the vocals did changed - though one can listen to the vocal their conversation sounds - unnatural.
After removing noise is there another approach to redeem the vocals of those speaking?
Thanks!

Yes, you have very much overdone the Noise Reduction!
First, I'm not sure why you would need to first apply a "Hard Limit".
Second, are you sure you followed Bob's advice exactly, i.e taking a new noise sample and changing the FFT size on each pass? Are you sure you set everything exactly correct on that first pass?

Is there a way to apply noise reduction based on ISO value?

I shoot a lot of sports using auto ISO which means I get hundreds of images from a day with a variety of different ISO values, including all sorts of intermediate values (like ISO 280, for example). There are times when I'd like to apply LR noise reduction across the whole batch of images, but I'd like to apply it based on the ISO value of the image. For example at ISO 1250 and above, I want a particular NR Luminance value. From 640 to 1250, I want a different value. From 400-640, a different value. I know you can define some things at import time based on ISO, but that doesn't seem practical when the ISO value can be nearly anything as it would take hundreds of import profiles.
So, any ideas how to apply NR based on the ISO across a batch of images?

How do "defaults" interact with a preset applied upon import? I shoot RAW and apply a preset upon import for every import I do. If I apply a preset upon import will it override the "default" anyway? If that's the case, then defaults are of no use to me.
Yes - Lightroom presets are absolute, but unlike the default settings, presets don't have to specify all the settings. If a preset setting is specified, it will blindly overwrite the previous setting, if not specified then the previous value will remain unaltered.
DevAdjust supports relative presets: final-value = present-value +/- relative-preset-value

Why does PhotoShop CC 2014 crash my Windows 7 Professional 64-bit PC every time I try to use Sharpen/Blur Reduction and also Noise Reduction ??!!!???

Hi Adobe
You a have a really wonderful PhotoShop CC product. It's really great, and I know new versions such as 2014 have their teething problems.
But I am getting really sick of my Windows 7 Professional 64-bit PC being crashed whenever I try to use PhotoShop CC 2014 Sharpen / Blur Reduction and also Noise Reduction.
This happens both with JPG's and PSD's.
Please sort your **** out and get some patches out to address this quickly !!
Chris Tattersall

Chris,
It doesn't crash for everyone. A person could be forgiven for saying, in return, "Please sort out your **** system problems".
Trust me when I say many, many problems are caused by the computer system setup not being up to the needs of this cutting-edge graphics software. Photoshop is heavily dependent on the GPU, and GPU drivers are notorious for having bugs (they're primarily written to run games).
However, that being said, recent driver releases from both ATI and nVidia do actually work pretty well with Photoshop CC 2014.
What video card do you have?
What display driver version are you running?
If you're unsure how to tell these things, go into Photoshop, choose Help - System Info, copy the data, and post it here.

Is Lightroom really better for noise reduction than Adobe Camera Raw?

That's what I keep hearing from Lightroom users (who don't use Photoshop or barely touch it).
Which is better? or are they exactly the same? I'm not referring to a specific version, but I am personally using the latest Cloud versions of everything. I haven't tested it visually, I'm just now getting familiar with Lightroom.

Given the same version number, Lightroom and Camera Raw have the exact same sharpening and noise reduction. The only differences in ACR and LR are usability or UI aspects, the controls and rendering are the same.

Noise reduction works in preview but doesn't apply to file

I have a file that I would like to apply noise reduction to. So in the tasks menu I click Clean Up Audio, then under Noise I click Noise... From there I can play with the Noise settings and get it to clean up nicely. But when I hit OK, it doesn't apply the noise reduction. It seems to be doing something to the audio because the waveform changes.. just not reducing the noise as previewed. Anybody know why it wouldn't be applying the effect? Other audio editing options seem to work just fine.

It is a 16 bit 44.1 kHz mono sound effect.. it is noisy and sounds like it could have been 8 bit at some point in its life cycle.

Microfon problems s400 with noise reduction

Hello people,
have a problem with the microfon sound.
This recording is either noisy (without HD driver and with HD drivers without noise reduction) or it is distorted (with HD drivers and noise reduction).
Drivers I've tried from the Lenovo page and also from Realtek already.
here are a few tests
Noise: https://dl.dropbox.com/u/1182020/test% 20HD% 20with% 20the%% 20treiber 20nachhallred.wma

in the device manager for microphone stands for the version: 6.2.9200.16384 Microsoft.
Use Windows 8 Pro which I installed by myself.
Would be grateful for suggestions, I can not skype otherwise.

Dark areas have less bits to encode their values so a single bit of noise is a higher proportion of the total value.
For the basis of the default processing, to match the human eye’s response to dark and light, darker areas are brightened more than bright areas, using a non-linear gamma curve. This magnifies the noise in darker areas.
If you boost the brightness of dark areas using Shadows or Clarity, you are making that noise even more visible. Think of brightening as digitally increasing the ISO.
Adobe’s noise-reduction is calibrated to the original photo’s ISO setting, not how much you have digitally increased the ISO by brightening it, so if you have magnified the noise by extreme processing, you may be beyond what maxing out the NR sliders are calibrated to remove.
Exporting sharpening will sharpen any remaining noise.
Are you using the Mask slider in sharpen to keep from sharpening the noise grain in the Detail section? Use the Alt key while moving the mask slider to determine the optimal Mask level for a particular photo, where you can’t to have the edges indicated but not the wide areas of little detail.
It’s hard to guess what you’re seeing without seeing a screenshot.

How do I permanently disable Detail (sharpening / noise reduction)?

I did this a while ago with the LR3 beta, but I forgot how I did it.
Anyway, I want to disable Detail (sharpening and noise reduction) in the right hand panel forever, so that when I import new pictures, it's disabled by default when I start developing them (so I don't have to disable it manually for each picture, which is very annoying). The reason is, I handle sharpening & n.r. as a separate step outside of LR (export as TIFF and then n.r. and sharpen).
Any hints please? I know it's simple, I just can't remember it.
Thanks.

first select an image, then drag the Sharpening Amount and Noise slider to zero, next choose Set Default Settings from the Develop menu. When dialog opens hit the Update to Current Settings button. If you have photos from more than one camera model you'll need to repeat process for each camera. The following tutorial should might also be worth reading http://www.computer-darkroom.com/lr2_camera/lr2-camera-defaults.htm

Why is Noise Reduction only available with some raw files

I have been going through my CRW, CR, and CR2 raw files and have noticed that some, when opened in ACR, do not allow me to adjust all the parameters in Noise Reduction. I thought it might be ISO related, but with a group of identically created raw files, some have full Noise Reduction adjustments while the next file will not. The only group that offers full adjustment with all files are the newer CR2 files captured with a 5D Mark II. Older 5D and 10D raw files are a hit and miss.
Am I missing something?
Thanks,
Kim

Another way is to just go into the Camera Calibration tab and select the 2010 process.

How do I permanantly apply audio noise reduction in FCP X

I have a clip shot on a blue screen set that had some noise in the background (constant hum from air conditioner). The Background Noise Reduction in FCP X, applied at 100%, does a truly amazing job. But there is one huge problem. It appears that FCP X "learns" as the clip is played, perhaps taking it's own noise print of the background noise, and applying it on the fly. Because for every clip I apply 100% background noise reduction to, that clip begins playing and you hear the full audio with noise. After a few seconds the backgroun noise begins to fade away. After playing for about 5 seconds, the background noise is completely gone. And it's freaking amazing. Better than what I've ever been able to accomplish with Soundsoap or other programs. But the fact that it must do this on the fly each time means it is unusable to me. I can't have each clip in my timeline start with noise, then have the noise drop out after a few seconds. Is this a bug? Am I doing this wrong? There are really no settings. You either have Background Noise Reduction on or off and set your percentages.
I am fixing audio on a 1 hour program. Really need this to work. Anyone else having the same problem, or found a solution? Or know what I might be doing wrong?

Does this mean you actually like the audio to sound as though it was recorded under water? I guess it depends on the amount of noise that requires removing, but I've never been able to tolerate more than about 40% before the audio gets horribly distorted.
I really don't share your experience of FCP X removing background noise 'on the fly' (sorry).

How do PS CS3 Noise Reduction Filters compare with dedicated third-party plug-ins?

Am I missing something by not installing a dedicated Noise Reduction application into my PS CS3? Can Neat Image, Noise Ninja, Noiseware Pro, etc. do something that the PS CS3 Noise Filters can't do? Do these third-party aplications do it better?
Since I like flashless photography, and I generally carry with me small-sensor compacts when I travel, I'm frequently confronted with the problem of digital noise. I've always wondered how the third-party noise reduction applications perform in comparison with the Photoshop Noise Filters. I hope someone in this Forum has been able to acquire direct experience on this topic and will be kind enough to share this experience with us.
Kindest Regards,
Conrad

Conrad,
ACR 4.3 has better NR (noise reduction) than previous versions and can handle NR in most normal situations. However, available light photography with a small pixel sensor may require more NR and the specialized plugins such as Noise Ninja, NeatImage, and NoiseWare Pro can do a better job. I have all three and they do an excellent job, but I currently use NoiseWare most of the time.
Here is a demonstration of NoiseWare vs ACR NR, using 100% crops of an image taken with the Nikon D200, 1/320 sec at f/2.8. The image is reasonably sharp at normal viewing conditions, but has quite a lot of luminance noise. It was rendered with ACR and the settings were exposure +0.85, brightness +60. One thing you learn early in this type of shooting is to expose to the right to reduce noise, but this may conflict with stopping action and reducing camera shake. More exposure would have helped this image, and one should try to avoid exposures requiring this amount of positive exposure adjustment.
The results are shown below, followed by some discussion. Other comments are welcome. Color noise is not prominent in this image and I left color NR at its default.
ACR, No sharpening, no NR
ACR, Luminance NR 53, no sharpening
ACR, No NR, No sharpening, NoiseWare default, no sharpening
Noise reduction and sharpening are antagonistic processes. It is important that NR is applied before sharpening--you don't want to sharpen noise. Following NR there is an inevitable loss of detail, and some sharpening is necessary to restore the detail, but this also brings back the noise. One can use masks and blend if sliders in Photoshop in both NR and sharpening to mitigate some of these effects, and Bruce Fraser discusses the details in his excellent book on sharpening.
If you use an add on such as NoiseWare, you should turn off luminance sharpening in ACR. In doing so, you lose all those nifty sharpening features that have recently been added to ACR. I leave color NR at the default. It has a minimal effect on detail.
In adjusting the NR in ACR at 100% viewing, I estimated that a luminance setting of +53 was optimal. Beyond that, blotchy artifacts appear in the image.
For NoiseWarePro, I used the default settings with no sharpening. The NR effect is dramatic, but detail is lost and some sharpening is needed. This could be applied in NoiseWare or in Photoshop, perhaps with a plugin such as PhotoKit Sharpener. Personally, I have found that PK does not work well with this type of image because it bring back noise and produces artifacts.
In all of these examples, sharpening is needed following the NR. One could try to use surface masks to keep sharpening in Photoshop with the unsharp mask away from the edges. However, I find it is difficult to get a good surface mask, and I don't take the trouble.
For now, I use the sharpening built into NoiseWare. I don't know how it works internally, but it does have a slider for detail protection, and you can play with this to get the best result. It would be best to have the robust NR of the add ons built into ACR much like NoiseNinja is built into Bibble Pro. However, this is an ACR forum and I would expect that ACR is the preferred raw converter of those who frequent this forum.
After expending this much effort on the post, I hope to get some helpful feedback.

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.

Cant get noise reduction to work

when I apply the noise reduction feature to a grainly picture nothing happens. am I missing a step?

It's subtle. Maybe zoom in and look at it. The M key will let you toggle to the Master file so you can look at the before and after quickly.

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

Is there a video noise reduction facility on final cut pro x?

İs there a video noise reduction facility or plugin on final cut pro x?

I appreciate this is an old thread and things have moved on but...
I have just been given a whole load of GoPro footage to work with that is very noisey (video noise) and needs some work.
FCP X still doesn't seem to like 'Neat Video' which works well (at times) but apart from the hang-ups takes a lifetime to render. The 'FxFactory' module isn't really doing it for me... Has anyone tried the 'Pixel Studios' plug in contained in their ProLens offering?
Thanks
