Lightroom Noise reduction versus DPP

I have been playing with DPP for al little while because the EOS 50d wasn't supported until a few days ago. DPP has some kind of intelligent support of NR depending on the ISO of the photo. If I analyzed it whell it is supporting the NR level of the camera itself.
Is it possible to do this kind of NR in Lightroom also?
I know I can make defaults for an ISO level, but it would be very nice if Lightroom is able to get this kind of information from te RAW file. The same accounts for the sharpening, but this might be tricky.
Regards,
Olaf.

>I read on the internet that Canon and Nikon don't want to share that kind of information. Stupid! They don't sell software, so it shouldn't matter to open the information of their RAW files.
Well Nikon sells their Capture NX software. They don't give it away with their cameras (except for some short running promotions) like Canon does.I do believe Canon charges for updates. You would think that it would be in the camera maker's best interest to make their files as readible by anybody as possible as it makes their cameras more attractive to buyers, but they have a very strange worldview in which the RAW files are their files instead of the photographer's and that their software is by definition better in processing their files than any third party because they know all the secrets. They actually say stuff like that! Quite astonishing. The only thing we can do is to tell them what we think of that bull.
>Lightroom doesn't apply any luminance nr by default. This also accounts for the higher ISO levels?
Even at zero there is some luminance NR I think. There is also noise reduction and sharpening inherent to the tuning of the demosaicing algorithm. I think the tuning between more sharpness and less noise is dependent on ISO.
>Are there any more options which are depending on the ISO of the photo by default?
Where do you get this kind of information? I can't find any about this in the online help of Lightroom.
I think some intricacies in the color rendering also respond to this but that's probably the extent of it. Thomas Knoll (check the credits in Lightroom to see who that is) and others on the Lightroom/ACR teams have posted on this forum about these things as well as some people in the know. So I 'm giving you second-hand info here but you should be able to look back on this by searching for posts by Thomas and others. Doing this is very instructive anyway regardless of the subject.

  • 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.

  • When editing in Photoshop CS6 I lose the noise reduction applied in Lightroom 4

    When I apply the noise reduction in LR4 & 4.1 it's awesome until I send it to photoshop CS6 for editing...there the noise returns somewhat with larger spots highlighted (have to remove with spot healing)... looks even worse when I bring it back to Lightroom as a tiff. I have used Lightroom  (including beta) from the start and this is the first major problem I've incured. I shoot a lot of concerts & festivals....this really makes for a lot more work and time spent....I love LR4...please fix.

    It should't happen. Can you post an example?

  • Lightroom, Photoshop, RAW Presharpening, Noise Reduction Workflow Help

    I'm tying to determine a best practices route using Adobe Lightroom, Adobe Photoshop and Nik Software Sharpener and Dfine (Noise Management Software).
    I shoot only RAW with a Canon EOS 30D with good quality lenses.
    I import the RAW files from the CF card directly (DNG and save) into LR, add keywords, organize, etc.
    However, I am now at the point where I need to determine a sensible workflow that includes these steps:
    Import RAW into LR as DNG.
    Edit, as needed, in PS.
    Apply RAW Presharpening (as provided in Nik Sharpener).
    Manage Noise (with Nik Dfine (2.0 available in next 24 hours).
    Apply usage-based sharpening prior to printing or saving final file version.
    Maintain organization in LR.
    My original plan was:
    1. Import RAW in LR.
    2. Open in PS.
    3. Apply noise reduction.
    4. Apply RAW presharpening.
    5. Save (with new version being an "Edit" copy back in LR.
    6. Maintain organization in LR.
    I'm wondering, though, if I wouldn't be better off doing the basics to the files prior to LR import. Note that the Nik tools work in 16-bit mode.
    This is theoretically what I'm thinking, and would appreciate other user's input:
    1. Save RAW files to location on Mac.
    2. Apply Noise reduction to RAW files with Nik software within PS (perhaps automated, perhaps batched).
    3. Apply RAW presharpening to RAW files with Nik software within PS (perhaps automated, perhaps batched).
    4. Import noise- and presharpening-adjusted files into LR, with metadata additions, etc.
    5. Open files in PS as needed, with files becoming edit versions within LR.
    Any thoughts?

    To summarize, then:
    First time opening a RAW file from Lightroom, LR automatically creates a copy and appends "-Edit" to the filename. If it's a RAW file, only available option is the third option in the dialog box: "Edit a Copy with Lightroom Adjustments."
    Once opened in Photoshop, any number of adjustments can be made and saved. All adjustments are reflected in the -Edit copy when previewed in back in LR.
    If, later, I want to perform further PS edits on the -Edit version, I have 3 options as presented in the dialog box.
    1. "Edit Original (LR adjustments will not be visible)"
    2. "Edit a Copy (LR adjustments will not be visible)"
    3. "Edit a Copy with Lightroom Adjustments"
    Option 1 will open -Edit version #1 (but it will not show any changes made in LR to the -Edit file when opened in PS)
    Option 2 will create a copy of -Edit version #1 and open that new file, -Edit-2 (but it will not contain any changes made in LR to the -Edit file)
    Option 3 will create a copy of -Edit version #1 and open that new file, -Edit-2 and it will contain any changes made in LR to the -Edit file
    So, a typical workflow would be:
    1. Import RAW file in LR.
    2. Make adjustments in LR.
    3. If needed, open a copy (by default) in PS via LR (command-E).
    4. Adjust in PS, save.
    5. Adjusted file is stacked with original RAW file in LR.
    6A. Assuming no additional edits in LR, further PS adjustments can be made to -Edit version original, keeping just 1 stacked version in LR.
    6B. If additional adjustments are made to the saved -Edit version in LR, and further PS adjustments are needed, I must edit a copy of the -Edit file, ultimately resulting in a second stacked file.

  • 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 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.

    Torsten,
    Here's my favourite workaround. You could have done it too, and it's a simple, one-step solution:
    Don't pay for software without thoroughly testing it yourself first.
    If you've paid for Lr 5 before destruction-testing it and keeping a close eye on the forum (where this issue has been know about for ages), you've only yourself to blame.
    Adobe will fix it when they're ready and able to: but it doesn't affect me in any "I paid for this, I expect it to work" way, because I won't be buying Lr 5 until it is fixed.
    A really, really, really simple, inexpensive, trouble-free way to deal with all that stress...

  • Lightroom 3.6 DNG and Noise Reduction Problem

    Hello,
    I did a search and couldn't find this issue listed. I convert my Nikon D90 raw files to DNG. Never seem to have a problem with that except that the display(s) seldom shows the results of applying Noise Reduction (Color or Luminance). If my display is at Fit or Fill I don't see the results of what I am doing. If I zoom in to 1:1 or more, then I can see the results. All works fine if I am using a jpg file, it is just the DNG files that do this. If I want to see the entire picture with Noise Reduction applied I have to switch to the Library Module. Then when I go back to the Develop module the main display goes back to not showing the Noise Reduction, but the secondary display is ok until I apply another effect then boom, back to Noise Reduction not displaying. All of the other changes I make work just fine. It is just the Noise Reduction that causes the problem. This is really a killer when I am working on photos. This problem existsed before 3.6. Does anyone else have this problem? FYI - When I switch to the Library Module it takes a few seconds before the secondary display shows the photo with the Noise Reduction applied.
    I have a quad core 2.4ghz with 8gig of ram and Windows 7 Pro 64bit OS. Plenty of CPU and memory available.
    Thanks,
    Harold

    LR is designed this way to improve speed.  I think it varies, somewhat, with how high the ISO is where higher ISOs show NR more.
    I find this annoying, too, and which there was a setting to allow LR to compute the NR at lower resolutions if one chooses, instead of Adobe choosing things for us.

  • Noise reduction applied to high ISO .tif files in ACR 4.1?

    Evidently ACR 4.1 applies noise reduction to high ISO raw files from Canon cameras, even when noise reduction is turned "off" in the plug-in (and this results in smeared detail). I have a 5D that I bought specifically for its lack of noise in high ISO files, and I don't want a software program forcing me into using noise reduction and ruining all those marvelous details in my high ISO raw files. Can someone tell me if there is a similar problem with ACR 4.1 if you open a .tif file with it? If not, I'm thinking I'm going to use Canon DPP 3.02 to convert my raw files to .tif, and then use ACR 4.1 to quickly adjust exposure, black point, etc., all of which is awkward and slow in DPP 3.02.
    Rob

    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 and RAW

    I use a Rebel T4i, but the model really should not matter I think.
    When Hi ISO or Long Exposure Noise Reduction is set does it apply to RAW?
    I am under the impression that RAW get no additional processing. But I'm learning to look at my images in new ways. Something doesn't add up. It seems like the noise reduction is applied to RAW images. My mind is going to explode pretty soon if somebody doesn't set me straight.
    Solved!
    Go to Solution.

    Long exposure noise reduction is applied directly to RAW.  It's "destructive", burnt into the file.  It takes the noise readings from the second "dark" shot and subtracts them from the first image, and creates a single RAW out of it.
    High ISO noise on the other hand is just listed as a setting.  Programs like Lightroom will ignore it, but some programs, like Canon's DPP will apply it on import.  I don't use it so I can't say for sure, but I'd imagine that you can adjust it since it's just a setting.

  • 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

  • Base Sharpening and Noise Reduction D800/E

    Has anyone set up a base sharpening and noise reduction at different ISOs for the D800/E?
    I had LR all set up for my D300 and D700 so the base settings where used at import.
    Now I need to do it with the D800E and was wondering what others might be using.
    Thanks

      The current local noise reduction ist NOT the same as the one in the detail panel. It is a lof f less efficient.

    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.

  • 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?
