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

In the photograph 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 Luminosity Info so that the image doesn't look 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 the 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.

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 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 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 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.

Conclusions: 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).

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, none useful information according to the principles of noise reduction in Capture One, I did not find it. 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 speaks of high quality 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. Wonderful. 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 sensitivity for commercial shooting as well: amazing luminance noise reduction for smooth surfaces while maintaining fine details and good job to reduce 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 such grain imitation is even more preferable than a smooth picture. 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!

Grainy or digital noise in a photo is noise that occurs when taking a photo. Basically, they appear due to the desire to get more information in the picture by increasing the sensitivity of the matrix. Naturally, the higher the sensitivity, the more noise we get.

In addition, interference may also occur when shooting at night or in a poorly lit room.

The most effective way to deal with graininess is to try to prevent its occurrence. If, with all the efforts, the noise still appeared, then they will have to be removed using processing in Photoshop.

There are two effective noise reduction techniques: editing the image in Camera Raw and working with channels.

Method 1: Camera Raw

If you have never used this built-in module, then without certain manipulations open a JPEG photo in Camera Raw will not work.

Open the picture in the editor in any convenient way, and it will automatically load into Camera Raw.

1. In the plugin settings, go to the tab "Detail".

   

   All settings are made at image scale 200%

2. This tab contains settings for noise reduction and sharpness adjustment. The first step is to increase the luminosity and color index. Then the sliders "Luminance Information", "Color Information" And "Brightness Contrast" adjust the impact. Here you need to turn Special attention on small details of the image - they should not suffer, it is better to leave a little noise in the picture.

   

3. Since after the previous steps we have lost detail and sharpness, we will correct these parameters using the sliders in the upper block. The screenshot shows the settings for the training image, yours may differ. Try not to set too high values, because the task of this step is to return the image to its original appearance as much as possible, but without noise.

   

4. After finishing the settings, you need to open our snapshot directly in the editor by pressing the button "Open Image".

   

5. We continue processing. Because, after editing in Camera Raw, in the photo there is a certain amount of grains, then they must be carefully wiped. Let's make it a filter "Reduce Noise".

   

6. When setting the filter, you must adhere to the same principle as in Camera Raw, that is, to avoid the loss of fine details.

   

7. After all our manipulations, a kind of haze or fog will inevitably appear in the photo. It is removed by the filter. "Colour contrast".

   

8. First, copy the background layer with a combination CTRL+J, and then we call the filter. We select the radius in such a way that the contours of large parts remain visible. A value that is too low will return noise, while a value that is too high can cause unwanted ghosting.

   

9. After finishing setting "Color Contrast" you need to desaturate the copy with hotkeys CTRL+SHIFT+U.

   

10. Next, you need to change the blending mode for the discolored layer to "Soft light".

    

It's time to look at the difference between the original image and the result of our work.

As you can see, we managed to achieve good results: there is almost no noise left, and the detail in the photo is preserved.

Method 2: Channels

Meaning this method is to edit red channel, which usually contains the maximum amount of noise.

1. Open the photo, in the layers panel go to the tab with channels, and with a simple click activate Red.

   

2. Create a copy of this channel layer by dragging it onto the blank sheet icon at the bottom of the panel.

   

3. Now we need a filter "Edge Selection". Staying on the channel panel, open the menu "Filter - Styling" and in this block we are looking for the necessary plugin.

   

   The filter works automatically, without the need for configuration.

   

4. Next, let's slightly blur the copy of the red channel in a Gaussian way. Back to the menu "Filter", go to the block "Blur" and select a plugin with the appropriate name.

   

5. The value of the blur radius is set to approximately 2 - 3 pixels.

   

6. Create a selection by clicking on the dotted circle icon at the bottom of the channels palette.

   

7. Click on the channel RGB, including the visibility of all colors, and turning off the copy.

   

8. Go to the layers palette and make a copy of the background. Please note that a copy must be created by dragging the layer to the appropriate icon, otherwise, using the keys CTRL+J, we'll just copy the selection onto a new layer.

   

9. While on the copy, create a white mask. This is done by a single click on the icon at the bottom of the palette.
10. Here we need to be more careful: we need to move from the mask to the main layer.

    

11. Opening the familiar menu "Filter" and go to the block "Blur". We need a filter called "Surface Blur".

    

12. The conditions are the same: when setting up the filter, we try to preserve as many small details as possible, while reducing the amount of noise. Meaning "Isohelia", ideally should be 3 times the value "Radius".

    

13. You probably already noticed that in this case we also have fog. Let's get rid of him. Create a copy of all layers with a hot combination CTRL+ALT+SHIFT+E and then apply the filter "Colour contrast" with the same settings. After changing the overlay for the top layer to "Soft light", we get the following result:

    

When removing noise, do not try to achieve their complete absence, since this approach can smooth out many small fragments, which will inevitably lead to an unnatural image.

Decide for yourself which method to use, they are about equal in terms of efficiency in removing grain from photos. Helps in some cases Camera Raw, but somewhere you can’t do without editing channels.

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, how you can achieve the same effect, but in this lesson we will analyze the simplest and, in the opinion of the author, the most effective method how 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 simple 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 place a photo in in social networks, where the photo size is small, the photo will look normal. 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 to make the photo look 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 this Photoshop tutorial, we'll learn how to simulate film grain. Any version of Photoshop will work, but if you're using Photoshop CS3 or later (we're Photoshop CS5), thanks to Smart Filters, first introduced in Photoshop CS3, you'll be able to adjust any special effect parameter at any time. If you have Photoshop CS2 or earlier, just skip the Smart Filter steps and you'll be good to go.

In today's tutorial, we will use this frame:

Since the grain is very small, it may be difficult to see it in the screenshot, but here is at least approximately what you get in the end (we enlarged part of the image so that you can see it better). Your photo will be larger and the grain will be more visible. We will tell you how you can adjust the special effect at the end of the lesson:

Let's start!

Step 1: Add a new layer, fill it with 50% gray and set the mode to overlay

Let's first create a new layer in our Photoshop document, which will contain the grain imitating the film, so as not to damage the original image. Usually for this we just click on the icon new layer in the lower part layer panels, and Photoshop creates a new empty layer, but in this case, we need to fill it with gray and change the blend mode, so we'll do all this at the same time using the dialog box newlayer. Click on the icon new layer , holding alt (Win) / Option (Mac):

Photoshop will display a dialog box with options for creating a new layer before adding it. In the upper part of the window, set the name of the new layer film grain , then change the blend mode to overlay and just below select the option Fill with Overlay - neutral color (50% gray), by ticking the box:

When finished, click OK, and the dialog box will close. You won't think anything has changed, but in the Layers panel, you'll notice that Photoshop has added a new layer. film grain, placing it above the original layer backgroundLayer. Blend mode selected overlay, on layer thumbnail, which is to the left of its name, you can see that it is filled with 50% gray (this shade of gray is exactly in the middle between black and white). We don't see this gray in the document because thanks to the blend mode overlay this gray color is now transparent:

Step 2: Transform The Layer new layer into a smart object

If you are using Photoshop CS2 or earlier, you can skip this step. If you have Photoshop CS3 or later, click on the small menu icon located in the upper right corner of the layers panel:

From the menu that appears, select Convert to Smart Object :

Again, nothing seems to have changed, but in the lower right corner of the layer thumbnail film grain an icon appeared, symbolizing that the layer is now a smart object. This means that all filters of this layer will become smart filters, and, as we will see later, until the very end of the work, we will be able to make adjustments to them:

Step 3: Add Noise with a Filter Add Noise

From the menu at the top of the screen, select filter , then noise , then Add Noise :

The filter dialog will appear Add Noise. The noise we add will become the grain. To increase the amount of noise, move the slider Amount . Usually the appropriate value is 10 % , but it's still best to keep an eye on the image to find the best value for your photo. Check if options are selected Gaussian And Monochromatic at the bottom of the dialog box:

When finished, click OK, and dialog box Add Noise will close. We've zoomed in on a section of our image so that the added noise is more visible:

If in step 2 you turned the layer film grain into a smart object, in the layers panel below it you will see a filter Add Noise in the list of smart filters. We'll come back to this shortly:

Step 4: Applying the Filter Gaussian Blur

Now the noise seems harsh and not like film grain, so let's make it softer with with the help of a lung blur. At the top of the screen, select again filter, then Blur , then Gaussian Blur :

open Filter > Blur > Gaussian Blur

At the bottom of the dialog box, set the value Radius near 0.5 pixels. This should be enough to make the noise softer, but not "float":

Clicking OK, close the dialog. Ready! We created the grain like in the film photo:

Adjustment

If you think the grain is too obvious, one of your options is to lower the layer's opacity. film grain. Option Opacity located in the upper right corner of the layers panel. The lower its value, the more the original image will show through:

Another option is to change the blending mode of the layer. film grain layer With overlay on soft light , this is a less contrasting blending option than overlay:

If you change the blend mode to soft light, the grain will also become less intense

Finally, if you're using Photoshop CS3 or later and, as we showed you, have made all the filters Smart Filters, you can return to their dialog box at any time and adjust the special effect without losing quality. You will see the list of used filters in the layers panel under the layer film grain. Double clicking on the filter name will open the corresponding dialog box. For example, we will open the filter dialog Add Noise:

Double-clicking the Add Noise smart filter name opens its dialog box.

A window opens and Photoshop allows us to adjust the value. Amount, to reduce or increase the amount of noise. When finished, press OK, and the window closes. Smart Filters are a great new addition to Photoshop, so if you're still using CS2 or earlier, this is a good reason to consider switching to it.

That's all!
