Bug in Noise Reduction in Lr 5.2

When I zoom in on an image, and then make adjustments to Luminenescence, the changes don't appear unless I zoom out then zoom back in. This hasn't been an issue/problem in the past.

Thanks for the tip. I did try that but it didn't work. But, the problem was solved when I re-calibrated my monitor. I have a Huey Pro calibrating system hooked up but had disconnected it and forgot to plug it back in again. After going through the Huey process everything was fine. Again, thanks for taking the time to try and help me out. It was a real puzzle.

Hi,
It seems you have some screen resolution problems in your system. You can try upgrading your graphic drivers and change the screen resolution to 1024x768

RAW conversion bug with Noise Reduction

Hello,
I have found a serious bug in the RAW conversion when noise reduction is applied. When converting from two types of Canon RAW files (a CRW from a Powershot G6 and a CR2 from a 20d) I found that if you apply Noise Reduction to a RAW file on very low settings (the default setting in the NR function will produce this reliably) single-pixel lines appear at regular intervals throughout the image. Here is an example:
You can see several lines in this image:

Has anyone else had this problem? Can someone from the Aperture dev team fix this?

Well I find this filter is quite good in 'masking' block artifact that codec like xvid, or other low compression codec have. I only apply it if I find the block artifact is too much and I find this filter is less offending to my eyes than the block artifact.
In manual it said that if you have noisy video and want to lower the size then you can use this filter. It also blur the video a bit. But I suspect it is more than blur as I try gaussian blur in time line and the result is not as good. You can see the result as well. There is the tab between source and target and you can compare the result by togling between source and target tab.
BTW, anyone with 1 core, dual, or quad core, can you tried to encode with it? Just cancel it after few minutes as I want to see what is your processor utilization with this filter on. Also you can see how long does it take to process this video from the 'estimation time left'.

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.

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.

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).

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.

Camera raw filter 8.x artifacts (not posterization, not banding) when using noise reduction

hi. i use camera raw filter for frequency separation, using noise reduction. And these strange lines keep appearing and messing everything up.
What is this and how do i get rid of them. Maybe it's a bug of some sort? It looks like ACR is breaking the image to pieces and working with them individually and combining them back.
If the sliders are not 100-0-0, the lines reduces, but is still there

I am seeing the same thing in a random test image someone else posted of buildings at night. The discontinuity becomes more apparent if you maximize the sharpening but it is not there in the saved result so appears to be the difference between rendering for the display and rendering for output:
The output TIF does not have it:

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.

Noise Reduction Preview Volumes

I have an odd bug. It seems that sometimes (about 50% of the time), when I preview a noise reduction process, the volume is maximized. It's REALLY loud. I have no idea how it does it. I try turning it down, but the response doesn't seem to be related to what I do. If I stop playback, then start again, the volume may be normal.
I'm actually afraid to preview my noise reduction. Does anyone have any experience with this?

Weird Banding with Noise Reduction Filter

Working on a night shot of a building and processed through ACR7.2 and forgot to reduce the noise - and opened in Photoshop. Went to Filter/Reduce Noise and immediately get wierd banding in the window blinds. This banding is there regardless of the noise reduction settings and could not get it to go away - See attached screen shot of before and after applying the filter. So I went back and opened the file again in ACR7.2 and applied the Noise Reduction there and bingo, noise level dropped and looked good with no banding. Looks like the Noise Reduction capabilities in ACR7.2 are way better than the Noise Reduction filter - but surely the banding should not be there; especially if images do not get processed through Camera RAW.
Running latest version of Photoshop CS6 (latest patches applied), Windows 7 x64 16GB RAM, Intel 4000 with latest drivers installed. Camera file was ACR2 from Canon 5DMKII imported as a DNG file - then opened in ACR 7.2
Before Image Opened in Photoshop before applying the Noise Reduction Filter
After Image in Photoshop after applying the Noise Redcution Filter
Seems like a bug to me
By the way, the screen captures are from the image viewed at 100%
Mike

The aliasing effect you're showing is obvious, but are you saying the noise reduction operation also changed the color of the image?
I didn't think so. Your "before" image appears several steps removed from your "after" image.
It would be best if you'd capture a "before" image of your entire display just before and just after applying the filter that causes the aliasing pattern, and also specifically describe or screenshot the exact parameters being provided to the filter causing the problem as well.
In general, if you're getting aliasing introduced into high detail / high frequency parts of your images, you might find it advantageous to work at a higher pixel count - i.e., change the output size in Camera Raw so that you're opening images at an upsampled resolution. That's the only way I work, and I find it advantageous to have more pixels representing the image while editing in a lot of ways.

EARS ALMOST BLOWN OUT by Noise Reduction window

OK, I'm exaggerating a little here, but what just happened with STP could have caused some quite serious hearing damage, had I had the headphone volume turned a little higher.
Was listening to my mono 48khz 32-bit audio file for fine-tune detail... I set the noise print on a quiet section of noise, then opened the Reduce Noise window.
Now, I should say here that each time I played the mono audio it would play through both channels evenly, and show up in the master as bouncing around -20dB.
When I hit play in the Reduce Noise window, the left channel was playing at normal level, and the right channel began playing in my headphones at +6dB, causing my ears to ring for the past 5 minutes!!
Here are the settings I had in the Reduce noise window when this happened:
Noise Reduction: -60dB
Reduction: 100%
Tone control: middle
*anything I've done wrong here?*
I have had lots of issues with the stability of this application in the past, but this, to me, is completely unacceptable! I realize this is a discussion board and not a customer complaint board, however I would like to remind users who may check here frequently to be cautious when using this software that you don't damage your equipment or your precious ears!

Yes, this is very much a known issue. See the following posts:

I was very close to losing my hearing last Christmas when I experienced this "feature" for the first time. I really do hope no one actually gets his/her ears blown because of this bug. It's been a known issue for at least a year, and still no word or fix from Apple. Please remember to leave a note at Apple's feedback area; this forum is not the best place to write bug reports: http://www.apple.com/feedback/soundtrackpro.html

Noise reduction quick brush - no controls ?

Hi,
After the upgrade to Aperture 3.1, if I apply the Noise Reduction quick brush, I can't see any controls or sliders in the adjustment brick. Does anyone else face this problem ?
I have no idea what should be in there, as I haven't used it before. Only tried the regular NR brick.
It doesn't seem to do anything to the image, even high ISO ones (I thought it might be linked to the RAW fine tuning brick, but it isn't).
Could someone please shed some light on what this tool does, or if you have faced the same issue ?
Thank you
Viren

I'm just agreeing with the OP. The NR Brick works as expected. The NR Quick Brush has no effect whatsoever, and, oddly, it shows up as a separate Brick from the regular NR Brick.
Let's go to the screenshots, all taken at the same exact spot on a 24 MP image shot raw at ISO 800 f/2.8. All details at 1600%
As shot:
/___sbsstatic___/migration-images/126/12613196-1.jpg
After noise reduction applied to entire image via the NR Brick w. default settings:
/___sbsstatic___/migration-images/126/12613196-2.jpg
Without the regular NR Brick, but with NR Quick Brush applied to this area, default settings, strength at 100%:
/___sbsstatic___/migration-images/126/12613196-3.jpg
QED. The NR Quick Brush does nothing. An ugly bug.

Noise reduction not applying to beginning of clip

There's a bug in Premiere Pro which results in the hiss reduction or certain audio effects not being applied to the first 2-3 seconds of audio when exporting.
After looking this up on the Adobe forums I found other people with the same issue, and they were advised to edit the audio in Audition and reimport into Premiere Pro. I am having the same problem in Audition however.
I capture my noise profile, apply the adaptive noise reduction (or dehiss or whatever) and the audio sounds fine in the program. But when I export the first 2-3 seconds have the original hiss and you can then hear the effect kick in.
Can anyone help?! I offered to start doing video for my work and this is driving me up the wall.

Adaptive Noise Reduction is just that - adaptive. It identifies sources of dynamic noise over time, then reduces them.
If your clips don't have a few seconds before the in-point with which to apply the algorithm, you can often just copy/paste a few seconds at the beginning of your recording, run the effect, then delete that section. Dropping a marker after you paste the selection (while it's still selected) will make it simple to select that range again for deletion.
Otherwise, you might want to try the more manual NR tools. You'll have more control over what's identified as noise and how drastically it's reduced, and can make several light passes for better results.

Iphoto11, noise reduction dont save. it goes retour to de original if i restart the programm.

If i use "noise reduction", iphoto maks it. it works. but if i quit the photo or copie the photo, ist lost de reduction effect.
(sorry for my englisch)

I'm suffering this same problem. Any changes I make to the de-noise slider are lost when the file is exported. Within iPhoto itself, the changes are visible. But the exported image shows none of the noise-reduction. I've noticed that this bug is present on all large images. Smaller-size photos do not seem to be plagued by this problem, however. I do hope that this bug is fixed soon.

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.

3. In the Library Module export to Hard Drive with 100% Quality no Sharpening
4. View the JPG and compare to the LR3 views...
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.
Man the 1:1 view issue is annoying! I want the image to look the way it does in Fit/Fill mode.... Is there a way to do this?
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?
