How to do Noise Reduction in Lightroom



When you capture images using a high ISO setting you will invariably end up with some noise in your photos. If the noise is distracting and if you want to remove it, then Lightroom can help.

A word of warning

Before start using any noise removal tool it will pay to understand that noise removal is generally achieved at the expense of losing some detail in the photo. This is because the noise removal process involves smoothing the image pixels, and this in turn compromises fine detail. In addition, the main Lightroom noise removal tool applies the fix to the entire image not just the areas where it is most visible, meaning that you can’t mask the result and limit it to only those areas you want to apply it.

Because of this, if you are a purist and noise reduction is an ongoing and significant need, then you may consider a dedicated and specialist noise reduction program such as Topaz DeNoise, Neat Image or Photo Ninja a worthwhile investment. However, for most photographers, the tools in Lightroom judiciously applied will suffice.

Identifying noise

Noise in photos comes in two types; color noise and luminance noise. Color noise is evidenced by multicolored pixels in an area of the photo that should show as a flat color. In the image below you can see that there are multicolor pixels in an area which should be solid blue.


Luminance noise is monochromic so it will be less colorful and more like grain. Here is luminance noise in the sky of a photo captured at an ISO of 6400 in early morning light:


Process versions

Whenever you import an image into Lightroom some noise removal will be performed automatically by the process version which is the camera raw technology Lightroom uses to adjust and render your photos. In each process version the technology has improved over that of the earlier versions. So each will render your photos differently and, in particular, Process Version 2010 included better noise reduction technology than the earlier 2003 version. This was carried forward to the 2012 version.

The current process version for Lightroom 4 and 5 users is 2012 so, if you have images in your catalog that you imported using an earlier version of Lightroom (versions 1, 2 or 3) which are still set to process version 2003 then you can achieve some immediate benefits in noise reduction by simply updating those images to the new process version. To do this select the images and in the Develop module from the Camera Calibration panel select 2012 (Current) as the process version (use the Sync option to copy the setting to all selected images).


Removing noise

To remove noise from a photo, open the Detail Panel in the Develop module to display the noise reduction sliders. There you will find sliders for Luminance noise and for Color noise.

noise-default-LRFor raw images Lightroom automatically applies color noise reduction in the import process. So the Color Noise Reduction slider will be set, by default, to 25 with Detail and Smoothness set at 50 for all raw images. The Luminance noise slider will be set at 0, with Detail at 50 (see screenshot on the right)

Adjust the slider for the type of noise you are seeing in the image, either color or luminance. If you are unsure what type of noise you have, adjust each slider in turn to the maximum value to see which removes the noise. In some cases you may have both types of noise, in other cases one type may predominate.

Once you know what type of noise you are trying to remove, adjust the slider for that type of noise by dragging it to the right. Aim to reduce the noise to an acceptable level, but avoid going beyond that point because, in doing so, you will lose some detail in the image.

Once you have adjusted the Luminance Noise slider you can then adjust its Detail and Contrast sliders. The Detail slider controls the luminance noise threshold – the higher the value the more detail in the image but, as a result, you may experience some residual noise. If you use a lower value you will get a smoother result but with less detail.


The Contrast slider controls luminance contrast so high values will retain more contrast but you may also see more noise and mottling in the image. Lower values will give you a smoother result but again at the expense of reducing contrast.

For Color Noise there are two additional sliders: Detail and Smoothness (the latter was added in Lightroom 5.2). The Detail slider controls the color noise threshold, so adjusting this to a higher value will protect detail in thin colored edges but often at the expense of removing speckled color. Lower values will give you some added smoothing of the color noise but, as a result, you may notice that colors bleed into each other. Adjust the Smoothness slider to help reduce low-frequency color mottling artifacts.

In this image, removing Color noise leaves some Luminance noise apparent:


Once the color noise is removed, the Luminance slider will remove the remaining Luminance noise:


When you are removing noise from an image it helps to be viewing the image at a 1:1 size ratio so you see clearly what is happening. Periodically zoom out to check the result.

Local Noise Reduction

If your image has luminance noise you can remove this from selected areas of the image using any of the three local adjustment tools: the Adjustment Brush, the Radial Filter or the Graduated Filter. These tools let you limit noise reduction to only those areas you want to affect, leaving other areas of the image unchanged. The downside to this feature is that there is no additional Detail or Contrast slider to fine tune the result, and it only works to remove luminance noise (not color noise).


Using any of these tools select the area from which to remove noise, and then adjust the Noise adjustment slider. Drag to the right to remove luminance noise from the image. If you drag to the left then you will add noise to the image.

When you go to sharpen an image that you have removed noise from, pay attention to the Masking slider in the Detail panel. Using this you can apply sharpening to only the edges in the image and avoid sharpening areas of flat color where the noise was most apparent.

  • Nice article! How is Lightroom’s noise reduction engine in front of dedicated plugins like Topaz’s or Nik’s?

  • Jason

    awesome stuff!! really helpful…keep em coming

  • Sois Ph

    thanks so much !

  • Raghavendra Kopalle

    One last step after all the sliders on LR would be to down sample the image which reduces noise further. Anyway not many of us would be using a 18-20 MP image, so reduce it to 12-14 MP as a final step.

  • Josie Longo

    I learned to use a combined total of 100 between the Noise and Sharpening tools. If you adjust Noise by 30 then adjust Sharpen by 70 for a total of 100. Then the Masking tool can give more precise sharpening by holding down the Alt/Option key while adjusting the slider. That last step makes a huge difference in the process.

  • Helen Bradley

    +Pierre Pichot – the proprietary plugins will typically offer more options in noise reduction – in particular the ability to mask the noise reduction effect so you apply it only where you really need it to be.

    However, if you want a pretty good tool without having to pay a chunk of extra change for it, then Lightroom is great.

  • Helen Bradley

    Thanks Jason.. glad you liked this post..

  • Helen Bradley

    Thanks +Sois Ph

  • Helen Bradley

    You make an interesting point Raghavendra…

    Downsampling can’t be recommended as a tool for noise reduction. However, if you do choose to reduce the size of your image (for other reasons), then you will probably (as a side benefit) see some further reduction in noise.

    And how do you downsample? Simply export the photo using the Export option and specify an image size smaller than that of the original.

  • Helen Bradley

    +Joise I have never heard of the combined total of 100 between noise and sharpening – I will keep an eye out for more information about why this would be recommended.

    You are, of course, correct about sharpening and the need to apply a mask to the sharpening. This is so that you don’t sharpen areas of flat color where the noise will be most apparent. Sharpening without applying a mask would be counter productive – you would effectively be sharpening the noise that you just worked hard to remove!

  • rebecca haegele

    Thank you for your clear explanation!

  • Raghavendra Kopalle

    Hello Helen, Yes it is not a tool per se but I tried this after reading it on many photography sites. I do this especially on high ISO underexposed shots after applying most of the steps you recommended in LR and yes by simply exporting in LR with lower megapixels.

  • Thanks for the answer. Masking the noise reduction seems very appealing to me. I’m going to try some demos.
    Lightroom is my main workflow tool, I think it’s the best piece of photography gear I’ve ever bought 🙂

  • Gee now that Josie has mentioned it that sounds familiar!

  • Dennis Ederer

    Excellent article on a subject that I still struggle with. I’ll print the article and insert into my binder of favorite workflow articles for challenging image edits. I look forward to the weekly newsletter. Thank you for sharing your wealth of knowledge.

  • Bobby Stewart

    The first person I heard using that formula was Serge Ramelli.
    And I find it works pretty well in general.

  • Benn Brown

    this will work but its purely psychological:) the noise is still there, you just cant enlarge as much as the full size so the image “appears” to have less noise:)

  • Zullu

    how about banding … that ugly jagged transition from grey to a light grey for example … how do you remove banding without adding noise to the “gradient”

  • Orton

    why don’t you shut up

  • Gonçalo

    Great article indeed, but I have a doubt… Taking into account that sharpening can possibly increase noise, should one leave out the sharpening step (with images that have a big amount of noise) thus lowering the amount of noise reduction used. Or should sharpening be used nevertheless, and then use noise reduction, even if with a higher amount?

  • Chris Tucker

    I like the app, Define2 for noise reduction in LR or PS

  • For LR-based noise reduction I find I personally prefer using, for Luminance and Colour respectively:


    There’s still going to be some noise left, but to me it looks closer to grain on film without any excessive smoothing of areas nor introduction of noise-reduction ‘jaggies’ anywhere which have to be dealt with manually (unless you push the thresholds further, blurring everything into an ugly soup). Overall image detail is retained and the noise which may be sharpened if applying an unsharp mask in PS later isn’t as bad.

    Of course, if you’ve access to PS anyway you could also use two versions of your image; a more heavy-handed version and one which has a more restrained noise reduction applied, then using layers you mask in the NR where you want it and don’t where you don’t. I think employing luminosity masks to denoise shadows (where detail will be lessened anyway) a bit so they don’t appear quite as muddy may work well, though it’s only something I’m thinking of and not something I’ve actually tried myself yet.

  • Sebastián Méndez

    such sloooooooow video.

  • Great article! I am struggling with photos from the conference, where background was lighted properly but stage with speaker was dark because of the better quality of what was on the screen. That’s why I had to use higher ISO and the photos have lots of noise. This artile will help me with editing!
