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:

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%:

QED. The NR Quick Brush does nothing. An ugly bug.

  • Noise Reduction + Adjustment Brush = Smooth Skin

    A combination of the amazing new Noise Reduction feature in an Adjustment Brush would be the ideal solution for Skin Smoothing.

    I confess (due no doubt to my complete lack of appreciation for the Adobe development process), I thought they might slip lum-NR into the brush before releasing Lr3. Oh well - de-sharpening brush works pretty good too.
    The "de-sharpening" brush is de-sharpening from -1 to -50 and actually blurring from -51 to -100.  Combined with -clarity, I find it very effective on skin.

  • Nikon D70s + Process 2010 + Luminance Noise Reduction + Adjustment Brush = blurry picture

    Please let me know if you have experienced the following and if it is a known bug:
    I'm processing a very noisy Nikon D70s raw photograph with Lightroom 3: In the develop mode, I applied the 2010 process under Camera Calibration, and then set the Luminance Noise Reduction to 98 in the detail panel. At this point, the resulting improvement over the original is dramatic and the details are rather crisp given the original condition of the photo.
    However, the moment I apply a local adjustment to the photo, bluriness is introduced to the photo; the bluriness affects the entire photo and not only the areas impacted by the local adjustment. This undesired effect appears with the adjustment brush and gradient and the only parameter that the local adjustment applies is an increase in the exposure by 0.01, which should normally not produce much of a visible effect.
    I exported the photo to a jpeg and found the undesired effect in the jpeg file.
    I believe this issue has a relation with the RAW file coming from a Nikon D70s as I performed a Sync of all the settings on RAW photos originating from a Canon 30D, and from a Canon XSi and did not see any of the undesired effect.
    These steps appear to be reproduceable on any of the Nikon D70s RAW photos that I have in my catalog.
    Please share some feedback.
    Thanks,
    Bruno

    The NEF and xmp files are now available at http://drop.io/LR3BugAdjBrushNoise8736
    In the current development settings, I added an adjustment brush to the ceiling with an exposure adjustment of +0.01 simply to demonstrate the issue. As soon as the adjustment is applied, bluriness can be seen and is most apparent in the faces but can also be seen on the wooden floor and everywhere else.
    I also noticed that by setting the mask to show (O), ditthering can be seen in the mask even though it was applied with feather, flow and density all set to 100%.
    Let me know what you think.

  • How to separately control color and luminescence noise reduction?

    Most of the time a little bit of Chroma noise reduction is all I need. I don't want to degrade the sharpness by applying luminescence blur unless I have to. Lightroom 3 has separate sliders. Is there a way to do this in Aperture 3?

    What code do you already have for changing the color and the number of elements?  Whatever it is you need to somehow tie that to being able to control it with a slider.  Would this be one slider to control both properties, or a different slider dedicated to each?

  • 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 function built into built into graduated filter and adjustments brush!

    Really useful functionality, but maybe the tool name shout be "Noise reduction" rather than "noise" for the graduated filter and adjustments brush.  If I understand it correctly, the way all the sliders work now is that that movement to the left decreases the function of the slider, and to the right increases the function - if that is the case, then by labelling the slider "noise" would suggest that moving to the right is increasing the noise when in fact it is the reverse!

    The explanation is that "noise reduction" doesn't fit the available space in all languages.

  • Improvements: Noise Reduction Shadow Details, Geometry Correction & More

    Loving what I'm seeing so far. Experimented with this last night and was very pleased what I could do in 10 minutes:
    http://frontallobbings.blogspot.com/2012/01/lightroom-4-beta.html
    Almost negated any need for HDR bracketing. I'm impressed. That said there's a few things I'd like to see still:
    1. Noise Reduction shadow weighted areas. It would be nice to selectively control noise in only areas that really need it. Especially in terms of shadow recovery, only that area needs the noise reduction applied. It would be nice to have a dark/light slider to apply to that specific function.
    2. Geometry Correction. This needs a serious update guys. It fixes a few things, but there's many other applications that do it way better (DxO Optics for one). It's a little too basic and could use better keystoning controls. I get better results from DxO Optics rather than use a Tilt-Shift lens.
    3. The publish modules are still very antiquated and limited. No control over profile selection and still no way to update folders from previously published images. You guys need to really hire Jeffrey Friedl to do your modules. He's done amazing work with most of his plug-ins.
    Good work so far with this version, looking forward to the release.

    This, please!
    Selective NR with brushes it great, but trying to use that to do NR in shadows is a real pain. Just a slider to weight NR to shadows would be a real boon. Ultimately it would be nice to have a full set of NR controls for shadows with a threshold slider to adjust when it kicks in.

  • Feature request: local noise reduction...

    I love the local corrections in LR2, and I'm using especially the local sharpening feature a lot. But I'm really missing a local noise correction feature (at least for luminance noise). It's such a shame to be able to do about any correction that I need inside Lightroom, but still having to make a round trip to an external noise editor to remove local noise. Especially since doing noise reduction as the last step doesn't seem to be very efficient at all.
    Local noise reduction would make this already great program so much better (at least, to me).
    Richard

    >My understanding is that sharpening does not add noise, but emphasizes the noise that's already there, making it appear from being insignificant to noticeable.
    We're being overly semantic here of course, but it just depends on how you define it. If you define noise as for example the root-mean square deviation from the "real" image (a very common definition but it ignores the noise's spectral distribution), than absolutely sharpening a noisy image adds more noise. Sharpening operates as a high frequency amplifier, amplifying edges that are just noise instead of real edges, so it basically amplifies the noise that is there, leading to an increase in apparent noisiness. The same is true for clarity. Clarity is basically a sharpening operation at a very high radius. If your source image is noisy (especially if it has a lot of low-frequency noise - i.e. "grain"), it will also amplify it. Conversely, negative sharpening results in reducing high frequency noise. as it is just a small radius blur effectively.
    >Moreover, sharpening in LR develop is considered capture sharpening, where the small loss in sharpness form the RAW format is regained.
    The sharpening brush is different as it is meant to be a creative sharpener. It definitely amplifies noise if you push it. And even so, using Develop's capture sharpening, it is indeed possible to amplify (=add) the noise using the capture sharpening if you use the controls wrong. The capture sharpening has the superb mask generator that can be used to protect areas that are not edges, limiting its tendency to amplify noisiness. However, it will amplify noise near edges, sometimes making them appear as if you have a waterpainting. This is also an example of amplifying noise. Remember, even if these tools are meant to do a certain thing, it doesn't mean they cannot be made to do something else.
    >To just regain lost RAW sharpness at the expense of noise would seem almost like defeating its own purpose.
    Sharpness and noise go hand in hand. There are smarter and less smart algorithms but fundamentally, sharpening always amplifies noise, and noise reduction always reduces sharpness. As I said some algorithms are better and limit the effect, but the bottom line is that there really is no way around this.
    >Or, is it more correct to say that applying -ve clarity/sharpening will make the noise "Appear" less obvious, but not actually get rid of it.
    Appear less obvious is exactly the same as reducing it. Your eye is very good in judging noisyness as it is very good at recognizing patterns and so you can easily see what is noise and what isn't. If an image appears less noisy, it is less noisy. Computers are not that smart yet and if you call a tool clarity, it does not magically know how to not amplify noise or how to not reduce noise when using it negative. Same with sharpening.
    Conclusion: negative sharpness & negative clarity == noise reduction. They are just not as good as some dedicated noise reduction algorithms as they are not primarily coded to do noise reduction. They do have that effect however.

  • LR3: lack of processing feedback after applying noise reduction

    Now with the bigger RAW files (7D's 18Mpix) Lightroom is becoming really slow.
    On several ocassions after applying some noise reduction, and waiting for some 20-30sec for a visible result, I moved the slider back and forth in the wrong assumption that nothing happens, but in fact I was disrupting an ongoing operation. The problem in LR3 is that it does not show any of its tooltips with an information that a noise reducing operation is in progress.
    I hope that the team would improve this in the next version 3.01, we need at least the tooltip to appear.
    Thomas

    i absolutely agree!
    Now, in LR3 you can move the sliders very smoothly - but nothing happens for seconds.
    Same happens with the local adjustment brush. You click on the picture and start to paint but nothing happens. After a few seconds the pin appears and MAYBE the first click for the mask is set. After that you can paint further.
    Another thing is, that it takes longer for a RAW to be loaded. Sometimes i see the "Loading"-Hint for 10 Seconds or more. If i need to scan fast thru hundreds of pictures to clone away some things or make a face a little bit brighter, these loading times feels like ages.
    Both is very annoying and was better in LR2.
    BTW: I think LR3 has a serious memory leak because i can see LR3 slowing down over time. After developing about 20 pictures everything slows down, sometimes to a point where i think LR3 has frozen (no CPU usages, just standing still for 30 seconds or more). When i quit and restart LR3, everything is quick until the next slow down.
    (older iMac 24", white model, 3GB RAM that can be used) - you may see this at a later point if you have 8GB or more RAM of course.

  • Lightroom 5 Noise reduction

    The advertisement for Lightroom 5 says
    Superior noise reduction
    Get amazing, natural-looking results from your high ISO images with state-of-the-art noise reduction technology. Apply noise reduction to the entire image, or target specific areas.
    Where do I find and how do I use this feature?

    In the Develop Module you will find Noise Reduction in the Detail Panel.
    To apply to a specific area you can use the Adjustment Brush (Under the Histogram) to paint on the areas where you wish to control Noise. The amount will be determined by the Noise Slider.

  • Noise Reduction Mask

    There is no masking tool for noise reduction like there is for sharpening (only the other way round, so it masks out sharper transition) either in Lightroom 3 or Lightroom 4.  I cannot hazard a guess why not and wonder whether such a thing could be included in the final version?

    +1!
    The inverse of the Sharpening Mask!  Hold down ALT while adjusting the Luminance and Color sliders to view in real time.  Would be awesome.
    In the interim I've found the following workflow helpful when applying global NR...
    1) Get rid of color noise first - easily done, get it out of the way for when you evaluate detail
    2) Crank Luminance NR, crank NR Detail, zero out NR Contrast
    3) View at 3:1, nice and tight, find a section that has smooth and detailed areas
    4) Move the Detail slider back and forth and pay attention to the blur on the fine detail.  Too high and you'll get the detail back but noise as well.  Too low and will be blurred into obscurity.  Look for the best balance
    5) Do the same thing with NR Contrast.  Up and down and watch for changes. Frankly this control is so subtle I find it insignificant.  Probably aren't looking for right things.
    6) Settled on those zero out the Luminance NR and start to raise until you are satisfied with the overall noise levels, knowing that your detail will be protected from above.  Work your sharpening to compensate for any softening (and use the mask so noise in flatter areas isn't exaggerated).
    Now we can add the local NR brush to fine tune further and add or reduce that global application selectively. 

  • 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.

  • 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.

      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 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.
