Noise reduction filter in photoshop. How to remove noise in photoshop

In general, the noise is a whole, unpleasant problem of digital photographs taken at night, and now we are solving this problem with you. First, let's open our noisy image and evaluate the situation as a whole.

We go to the menu File/Open or use hotkeys CTRL+O. By the way, you can also open an image using the " Open as...» ( ALT+SHIFT+CTRL+O), find and select our image with noise, then to the right of the "File Name" field, select open as the file type "Camera Raw" and our image immediately opens in the Camera Raw filter.

I open my image first, in the usual way, to further show how to go into the special "Camera Raw" filter, select the desired tab and perform denoising operations. Now let's evaluate my image, which has chroma and luminance noise. Here it is:

Image with color and luminance noise

There is more than enough noise in this image. You probably have already begun to doubt that we will succeed .. Of course, it will not be possible to completely remove all the noise, but it is easy to make the image less noisy. Let's move from theory to practice!

Step #1

So, I opened my image in Photoshop, now I need to go to a special filter - "camera raw filter". To do this, I go to the top menu Filter/Filter Camera Raw, or use hotkeys ( SHIFT+CTRL+A).

Go to Filter/Filter Camera Raw...

Step #2

The Adobe Camera Raw filter window opens in front of us. We put a tick at the top in the "Control view" item to immediately see the changes in the image while working in the filter. Next, select the "Details" tab, I have this third icon on the left. In the lower left corner, you can change the image scale, we will need it soon.

Step #3

We find the "Color" slider and slowly move it to the right until the color points disappear. Do not try to remove the luminance noise at this stage, for now we are removing only the color noise (color points). As soon as the color dots disappear, immediately stop moving the slider.

Zoomed the image up to 300%

This is what we got at this step after some simple manipulations with the "Color" slider. Note that the colored dots (color noise) have completely disappeared from the image. Now it remains to remove the luminance noise.

Color noise in the form of color dots is completely removed

Step #4

Now let's start removing the luminance noise. In order to do this, we find the "Luminance" slider and slowly move it to the right side, while observing our image in parallel. When it is enough, we determine it individually in each case, but the value of "Luminance" in any scenario is always higher than the value of "Color". Here's what happened:

This is the picture we got, the noise is almost completely gone

Step #5

As a result of all our manipulations, the sharpness of the image has decreased. To increase the sharpness, move the Effect or Brightness Info sliders to the right. You can move these two sliders or any one of them.

But keep in mind, you need to move the sliders very carefully, because you get the opposite effect, the more you add sharpness, the more noise appears. At the end, do not forget to click the "OK" button in order to save all changes.

Sharpening Carefully

Now let's look at the result of all our work to remove noise from the image. As a result, we got an image on which there is practically no noise, the result is quite decent. I think now you will no longer have a question about how to remove noise in photoshop.

This is what happened after processing to remove noise

Noise can ruin the most beautiful photo, which is why the ability to remove it programmatically is so important. Using Photoshop, you can significantly improve a noisy photo by improving its quality with the help of special filters.

In the photo taken as an example, the background noise is visible only when approaching, but it spoils the impression of the work. Let's try to fix this using the standard program filter.

Select Filter>Noise>Reduce Noise and set the values ​​in the dialog box that opens. For this image, the settings are as follows:

As a result, the color noise is gone, and in general the image looks much better:

Even low quality photos can be corrected in Photoshop. An example of a photo with strong color noise taken in poor lighting:

Open the image in Camera Raw; To do this, select File>Open As and select the following format:

The first thing to do is to remove chrominance noise, for this we go to the corresponding filter menu, marked with an icon of black triangles.

Set the luminosity to maximum, and then adjust the "Luminance Information" parameter so that the image does not appear flat. After applying these settings to the preview, you can see that the photo has become blurry and has lost the clarity of the contours. You can restore sharpness using the "Sharpness Adjustment" menu - adjust the position of the "Effect" and "Radius" levers until you get a satisfactory result.

Now you can evaluate the quality of the improved image using before and after photos.

Photoshop filters Sharpness adjustment(Sharpening) and Noise reduction(Noise Reduction) - two functions that will help improve the quality of photos taken in poor lighting conditions, especially if you can not control the light - for example, at concerts (in this tutorial, a promotional photo of the musical Fame, taken by photographer Tigz Rice) or weddings.

Translator's note : To work with the lesson, you will need the Camera Raw plugin and Adobe Bridge of the same version as Photoshop. If you are using the versionAdobephotoshopCS6 then for photo editing modeCameraraw,need to go to the menu File> Browse in Mini Bridge (File>BrowseinMiniBridge), then find the desired photo and right-click on it. From the drop down menu select Open with > Camera Raw (openwith >Cameraraw). When working withPhotoshop CS6 can skip the first two steps. If you are working in Photoshop CC, then forphoto editing modeCameraraw,you need to go to the menu Filter - Camera Raw.

By using these Camera Raw filters, you can save photos that aren't as sharp as expected.

In this tutorial, Tigz will demonstrate how these tools can be used in a comprehensive way, including information on how each slider will affect the retouching result.

You will find out why the filter Noise reduction(Noise Reduction) need sliders Colour(Color) and Brightness(Luminance) - and which one to touch first - and why do you need Details(Detail) Contrast(Contrast) and Mitigation(Smoothing).

As a result, Tigz will show you how to apply these filters so that you can come back to them later - in case they need to be edited due to other adjustments made.

Step 1

Open the desired image, convert the background layer to a Smart Object. To do this, right-click on the layer, then in the drop-down menu select Convert to Smart Object(Convert To Smart Object). This will allow you to edit the applied filters later.

Step 2

Go to menu Filter>Camera Raw(Filter > Camera Raw). The Adobe Camera Raw plugin menu will open.

Step 3

Step 4

When you are satisfied with the result, move on to the tools Sharpness Adjustment(Sharpening) and Noise reduction(noise reduction).

Both tools are on the tab Detailing(Detail), third from the left.

Step 5

Sharpness adjustment(Sharpening) is controlled by one main slider - Effect(Amount) - and three additional ones: Radius(radius) Detailing(Detail) masking(masking).

Slider Effect(Amount) controls the amount of sharpening applied to the image. The "right amount" of sharpening depends on preference, but the value 25-35 will be optimal.

Step 6

Radius(Radius) controls the area of ​​sharpness compression around the edges of objects in the photo. The default value is 1.0, which means only one pixel of width along each edge. You can group up to three pixels in total.

Again, the "correct amount" of the parameter will depend on the particular image and personal taste, but 1.0 will do a great job.

Step 7

Slider Detailing(Detail) is responsible for the location of the sharpness in the photo: it is applied to an image with contrasting edges or low values ​​when shooting at high ISO.

Default setting Detailing(Detail) is set to 25, but as with the previous settings, the "correct amount" depends on your preferences as well as the photo itself. For live footage, which can often be too grainy, the value 25 will be great.

Step 8

masking(Masking) completes the set of four instruments in the group. Sharpness adjustment(Sharpening) and is the best of the three additional sliders. It allows you to have maximum control over where in the image the sharpening is applied.

If you hold down the Alt key while dragging the slider, you can see which areas will be sharpened. All black areas will be untouched, while white areas will be sharpened.

Step 9

Now let's move on to the module Noise reduction(noise reduction). It removes noise from images that occurs when shooting at high ISO, and also smooths out tones if the camera sensor was set to maximum.

Working with noise reduction(Noise Reduction), start with a slider Chroma(Color). It evaluates the color of the noise and mixes it with a suitable color to match a specific area of ​​the image. Usually it is enough to set the slider at the mark 20-30 .

Step 10

To improve the final result, you can use secondary sliders - Detailing(detail) and Mitigation(Smoothness).

Slider Detailing(Detail) controls how much detail will be shown after color sorting. I usually leave it at the default value - 50% .

Step 11

Slider Mitigation(Smoothness) smoothens uneven color that occurs when shooting, and works best at the mark 60-80% .

Step 12

Work with Chroma(Color) allows you to make small adjustments before moving on to the most serious slider - Luminosity(Luminance). The latter smoothes the entire image, so the result can be loss of sharpness.

Slider Luminosity(Luminance) is an incredibly powerful tool. For images taken at ISO up to 2000, a mark is sufficient. 25% .

Step 13

About brightness(detail) and Brightness Contrast(Contrast) allow you to return some of the details lost after applying Luminosities(Luminance). However, noise usually returns along with the details.

We first went to Chromaticities(Color), thereby minimizing the effect of Luminosities(Luminance), so both sliders mentioned above can be left at their default values.

Step 14

Once you are satisfied with the result, click OK to confirm your changes. A new layer will appear in the layers panel Smart Filters. It contains all the Camera Raw filter information.

Step 15

Since we were working with a Smart Object, the changes made can be corrected. To do this, simply double-click on the Camera Raw Filter layer in the layers panel.

Translator's note: inAdobephotoshopCS6 this feature does not work. To edit your changes, double-click on the small button with two stripes and two triangles above the photo thumbnail in the panelMiniBridge.

In this tutorial, Maxim Basmanov will tell you how to remove noise from a photo in Photoshop. This will be the easiest way for beginners, since most beginner photographers make noise in their photos, because they set the settings on their camera incorrectly, or they just take pictures with a phone or ordinary “soap dishes”. Yes, there are more professional ways to achieve the same effect, but in this tutorial we will analyze the simplest and, in the opinion of the author, the most effective way to remove noise in Adobe Photoshop.

Let's open the photo we'll be working with today.

If you look closely at the photo, you can see that there is a little noise on it. There is both color and plain monochrome. All in one heap, as is usually the case in photographs of this kind.

Of course, when printing on some small photos, or if you post the photo on social networks, where the photo size is small, then the photo will look fine. But if you have a need to use enlarged areas of the photo, then this noise will be visible.

Let's start removing this noise. First of all, create a copy of the layer using the keyboard shortcut Ctrl + J.

After that, go to Filter -> Noise -> Reduce Noise (Filter -> Noise -> Reduce Noise).

There are two ways here: Primary and Advanced. An additional method allows you to remove noise in certain channels. This is useful when you have a lot of color noise in your photo and one color dominates.

But we won't go into the more complex selection of noise and everything else, so in the "Advanced" mode, go to the "Above all" tab, remove all settings to zero and figure out what we can do here.

We start working with the "Intensity" slider. Increase the value of the setting until the noise merges and removes its hard edges. The noise becomes a little blurry, but does not disappear anywhere. There is still a lot of color noise in the photo.

Next, work with the "Reduce Color Noise" slider. Start moving the slider to the right. In our case, we increase the value to 90%. With this setting, we ensure that the noise remains, but the color disappears from it.

Now we have removed the color noise, but the normal noise is still there. Now we create a copy of the layer we have been working on. Standing on a new layer, go to Filter -> Blur -> Blur on the surface (Filter -> Blur -> Surface Blur).

Now we will blur the noise that remains. But before doing this, you need to know that not always in this way we can save all the elements in the photo. It's important to understand that the noise has already killed off most of these elements and so we need to at least just make it smooth so that the photo looks better than it is now.

In the filter settings "Radius" increase to a small size. Of course, it all depends on your photo, but you shouldn't get too carried away here. In our example, it will be 4 pixels. "Isohelion" - also do not make too large numbers, as the photo becomes very blurry. In our example, the author uses a value of 15 levels.

In the first part of this lesson, we analyzed the causes of noise in photography, its components, and what to do in order not to provoke their appearance. In this tutorial we will learn how to reduce noise in Photoshop, Capture One, Digital Photo Professional and Lightroom. All of these programs have a tool for reducing noise in photography, called in the jargon of photographers " noise reduction».

At this stage, you need to understand that:
• If during the shooting there are only two alternatives: to take a picture without noise (low sensitivity of the camera matrix) but not sharp, or with noise, but sharp, then I choose the second option. For you can’t get rid of blurriness, but you can still fight against noise.
• It is not always necessary to completely remove noise in a photo, often it is enough to reduce its level to an acceptable level.
• Luma and chromatic noise are removed differently.
• At 100% image scale on the monitor, we see noise several times larger in area than they will be on a print, in a printing publication or an online photo album.

In this tutorial, there are large photos that are automatically scaled if your screen size is smaller than necessary. When this happens, a 100% zoom button will appear in the top right corner of the photo. Only this scale will allow you to accurately assess the strength and size of the noise. To view those parts of the illustration that are hidden, drag the image with the mouse by its central part. To close the photo and return to the article, press the Esc key.

Initial conditions: all noise reduction is disabled in my camera, shooting is carried out in RAW format, the sensitivity is set to 3200 (I still allow this value in my shooting) and 6400 (we'll see if I can use this sensitivity in an emergency). For control, a frame was taken at a matrix sensitivity of 100 units. All shots were adjusted to +0.5 stops. This slightly increased the level of noise in the photographs, but exposure errors occur during shooting, so this correction is closer to the practical situation for the photographer. From the test shots were cut out ( photo 1): a) a fragment from the packaging of Shnyr's food (to control text sharpness and color distortion); b) a scale with fields of different lightness (control of the strength of noise in different tonalities); c) a fragment of the body of the mythical creature Gava (for greater beauty). On the photo 2 we see that with increasing sensitivity, noise spots grow in all target fields, which is quite natural and expected.

Photo 1: test photo.
Photo 2: increasing the sensitivity of the camera matrix leads to increased noise.
Photo 3: Luminance noise reduction reduces the sharpness of fine details in the image.

How to remove noise in Photoshop (Photoshop).

Oh, pranksters, didn’t shoot in RAW format or forgot to remove noise at the stage of converting a RAW file? Sometimes it happens. Open our photo in Photoshop, then in the menu: Filter> Noise> Reduce Noise… (Filter> Noise> Reduce Noise…). Here is our first tested noise reduction.

Luminous noise. It is the first two sliders (Strength and Preserve Details) that are responsible for reducing it. If we pull Strength (Strength) to the right edge, then we will see that the luminance noise is reduced, but the text becomes more blurry ( photo 3). The main evil of luminance noise: the fight against them leads to a decrease in the sharpness and detail of the photo. The attentive reader will notice that the slider Preserve Details (Save details), just, and is designed to ensure that the image does not lose quality. Move the second slider to the right, and you'll see the sharpness and detail return. But noises also return with it, it turns out "they changed the awl for soap." The settings I used for ISO 3200: Strength - 9, Preserve Details 6%. If your photo does not have small details, like text, texture, then Preserve Details can be reduced up to 0. For ISO 6400, these settings turned out to be rather weak, so I increased Strength to 10, and Details was reduced to 3%, somewhat to the detriment of text sharpness ( photo 5).

Chromatic (color) noise seems to be the lesser evil. By moving the Reduce Color Noise slider to the maximum value ( photo 4) text sharpness is not reduced, color noise almost disappears, but small objects lose color saturation (look at the red and blue box). Also note that a colored halo is formed around the red dies. Sometimes, such a change in the color of small details can be critical and impossible for a photograph. Therefore, we should try to apply noise reduction to a minimum degree: for ISO 3200 I applied the Reduce Color Noise value of 70%, and for ISO 6400 - 100%.

On the photo 5 and 6 you see the result of noise reduction in Photoshop. If for ISO 3200, after noise reduction, noise manifests itself at a tolerable level and there is still some reserve for their greater suppression, then for ISO 6400 they are already excessive for some shootings, and I would try my best to avoid using this sensor sensitivity.

Photo 4: Reducing color noise can result in reduced color detail and color halos.
Photo 5: reduced noise in Photoshop, ISO 3200.
Photo 6: the result of using Photoshop noise reduction for ISO 6400.

Findings: Reducing luminance noise is impossible without reducing the sharpness of the photo. The use of noise reduction makes it possible to use a sensitivity of 3200 units, but a sensitivity of 6400 may not be suitable for increased requirements for photo quality. If you take photos for the Internet or small print, then I can use a sensitivity of 6400 units. By reducing luminance noise in a photograph, we do not get rid of chromatic noise, and vice versa.

Chromatic noise reduction in photography can sometimes go unnoticed by the viewer. But if color accuracy in small details is important when shooting, then excessive use of noise reduction settings in Photoshop is unacceptable, for example, when subject photography or in food photography. The more “gentle” the noise reduction settings we use (not only in Photoshop, in general, any), the better our image after processing.

Digital Photo Professional

The second for this lesson I chose Canon Digital Photo Professional(hereinafter DPP). This is a very simple RAW file converter for Canon cameras, and it is with it that I introduce the students of the photography course for beginners to the possibilities of the RAW format. In order to get to the DPP noise reduction, you need to select the NR / Lens / AOL tab on the Tool Palette (tool palette). Of course, we are interested in the Noise reduction block (noise reduction), in which there are only two sliders: Luminance ... - to reduce luminance noise, and Chrominance ... - for chromatic ( photo 7). As in the case of Photoshop's noise reduction, I tried to use such settings in DPP to maintain a balance of quality for fine details and smooth surfaces. For ISO 3200, the following parameters were used: Luminance - 7, Chrominance - 12 ( photo 8). For ISO 6400 - 12 and 20 respectively ( photo 9). The result is very similar to the one obtained in Photoshop's noise reduction.

Setting noise reduction in DPP. I've noticed that with my camera's noise reduction turned off, DPP applies its own noise reduction to RAW files. Turning off photo noise reduction every time is not convenient, so you need to make sure that DPP does not use it by default. To do this, go to the DPP settings (Ctrl + K keys), go to the Tool palette tab (tool palette), turn on the Set as defaults switch, set all sliders to 0, click OK, and restart DPP ( photo 10).

Photo 9: the result of applying the same noise reduction for ISO 6400.
Photo 10: DPP noise reduction settings.

Capture One

To date, Capture One is my main RAW file converter. As in the case of DPP, its noise reduction ( photo 11) is not disabled, and applies to RAW files regardless of camera settings. Moreover, even when there is no need to reduce noise, for example, at low sensitivity. I did a little research on the noise reduction algorithm in Capture One, and it interested me so much that I decided to read the help of this RAW converter. Alas, I did not find any useful information on the principles of noise reduction in Capture One. Therefore, the results of my conjectures, assumptions and research will be described below.

According to Capture One help, the noise reduction of this converter changes its settings after the file is analyzed. I confess that for several years of work in Capture One, I adjusted the settings for its noise reduction only a few times. Noise reduction works so gently, intelligently, unobtrusively and excellently in automatic mode that I simply forgot about its existence.

The first thing I checked was how my photo would improve when I removed the noise reduction settings for ISO 100. And nothing happened. That is, if there is no noise, then noise reduction does not work. Then I noticed that when increasing the sensitivity, only the Color value (affecting color noise) changes, but not Luminance (luminance noise). Then I assumed that with the same value of Luminance and with increasing sensitivity, luminance noise would grow in proportion to how it happens in the absence of noise reduction. It wasn't there. Noise increased, but not so much. I'm not going to guess how this happens, but I was pleased with the result of the intelligence of Capture One.

In the next experiment, I tried to find the minimum noise reduction setting that would satisfy me and compare how much softer my settings are with those that Capture One offers by default. The changes were so minor that they can be neglected: for ISO 3200, Capture One suggested a value of 25 and 54 (Luminance and Color), but I found softer values ​​\u200b\u200bto be acceptable: 20 and 50, respectively. For ISO 6400, Capture One's own noise reduction settings completely satisfied me, and I did not touch them (25 and 57).

There are a few other goodies to make noise reduction even more effective. Surface (surface) allows you to reduce large-scale noise spots on low-contrast, smooth surfaces, while not touching fine details such as text (value 70 for ISO 3200 and 90 for ISO 6400). Single Pixel allows you to remove single pixel noise (individual knocked out pixels) without losing fine details. True, such pixels appear only at ISO 6400 or when the matrix overheats in Live View mode. Despite the fact that the sensitivity of the matrix of 6400 units was used in the noise reduction test, I did not use this Capture one setting, since the impact of the main tools was enough.

I am very pleased with the quality and features of Capture One noise reduction. Unlike the denoisers discussed above, Capture One does not create color halos or reduce color saturation in small details of the image. Color noise in shaded areas is also significantly better suppressed than previous competitors. This indicates the high quality of the color noise reduction algorithm. Thanks to the Surface action, luminance noise also looks weaker, especially on plain surfaces.

You can see the results of noise reduction in Capture One on photos 12 and 13. However, it remains to test a competitor among RAW converters - denoising in Lightroom.

Lightroom and Adobe Camera RAW

I even downloaded the new Lightroom - 4.3... In all previous versions of Lightroom, its noise reduction, according to users, was considered a weak link and was not recommended for use. Those. after converting RAW files to Lightroom, noise reduction had to be done in Photoshop. But Photoshop's noise reduction loses much in the quality of at least Capture One, and I can't recommend this chain (Lightroom > Photoshop) for noise reduction. Out of the corner of my ear, I met a mention on the forums that Lightroom noise reduction, starting from the fourth version, has been improved. Wanting to clarify this information from experienced users, I again ended up on the Lightroom forums. And what I read there did not please me in any way: brakes, difficulties in work, glitches, in general, everything is as always with the RAW file converter from Adobe. This finally turned me off from installing Lightroom, and instead of its noise reduction, I will test a similar Photoshop tool - Adobe Camera RAW. I noticed a long time ago that the settings of these two Adobe products are identical, and lead to the same results after processing RAW files. That is, the operation algorithms of both programs are the same (it would be strange for one manufacturer to make two versions of noise reduction). If I'm wrong and you have a good reason for this, please let me know.

In order to reduce noise in Adobe Camera RAW, you need to go to the Detail tab (Details). This noise reduction has more settings than the noise reduction in Photoshop (photo 14). By default, for files of both sensitivities, Camera RAW offers not to reduce luminance noise, but to reduce color noise (Luminance - 0, Color - 25, Color Detail - 50). At these settings, color noise is nicely suppressed, and (as in Capture One) I don't notice any color halos. Perfectly. The Color Detail slider (color details) helps to adjust (return) color saturation for small details (remember, Photoshop had a problem with noise reduction). I left the default Color Detail value, i.e. 50. But I lowered the main Color setting to 15 (for ISO 3200) and 20 (ISO 6400).

Luminance patches on smooth surfaces remained visible but unobtrusive at Luminance values ​​of 55 (for ISO 3200) and 70 (ISO 6400), but did result in a slight reduction in text detail. Therefore, I chose a compromise value of Luminance Detail - 40 (for ISO 3200) and 50 (ISO 6400).

I really liked how Adobe Camera RAW reduces noise ( photos 15 and 16) that I was wondering if a wider use of the 6400 sensitivity on my camera is acceptable. If we added the Surface setting as in Capture One to this noise reduction, then it would have no equal. I wonder how the places among the noise reduction leaders will be distributed at the end of this photography lesson.

Noise reduction test results

The results of the noise reduction test in photos 17 and 18: the worst - at the top, the best - at the bottom. When shooting at high sensitivity values, I do not recommend using Photoshop's noise reduction for bitmaps and Canon Digital Photo Professional. The main reason is strong color halos around colored parts in the photo. It is also difficult to find a compromise between the level of luminance noise on smooth surfaces and the sharpness of fine details in these noise reduction devices. Capture One, against the background of the first two, looks to be in a winning position, until Adobe Camera RAW noise reduction comes into play. The latter showed that in many cases I can use the 6400 for commercial shooting as well: amazing luminance noise reduction for smooth surfaces while retaining fine detail, and a good job of reducing color noise. What do people working in Lightroom complain about, I don’t understand?

Conclusion

If during shooting you want to use high sensitivity values, then start dealing with noise at the shooting stage - shoot in RAW format. Do not shift the noise reduction process to Photoshop, do it in the RAW converter when correcting photos. Use the converter that with less loss (and loss is inevitable) will reduce the noise in the photo. Use the minimum noise reduction settings.

If the photo has strong noises, then in some cases it is possible to limit ourselves to reducing only color spots. The remaining luminance noise will be very similar to film grain. Sometimes this imitation of grain is even more preferable than the smooth picture of a digital camera. For example, if you stylize a photo as an old one. In other cases, the grain can give a certain charm to the picture ( photo 19). No wonder there are Photoshop filters that create a similar film grain. But, that's a topic for another lesson.

PS: Not the latest versions of Adobe Camera RAW and Capture One were used in this noise reduction test. Therefore, it is possible that the noise reduction algorithms in these programs have become even more advanced.
PS: Don't make noise!
