Sharpening in photoshop cs6. Universal sharpening. The Color Contrast filter in Photoshop

In this tutorial, you'll learn a few ways to sharpen an image, allowing you to "get around" the shortcomings of the built-in sharpening filters in Photoshop. What are these shortcomings? Let's start in order:

1. Color halos may appear around contrasting objects.
2. Color and monochromatic noise increases. If the second is not so terrible, you don’t even always need to get rid of it, then the first one literally hurts your eyes.
3. In the scanned photographs, the above disadvantages appear even more strongly, in addition, the graininess that was originally inherent in them increases.

As a rule, in the process of improving the sharpness of a photo, you have to increase the sharpness several times, which can further aggravate the situation.
How to avoid similar problems? Beginning (and not only) users are often confused by this. But there are several ways, plus their variations and combinations, that allow you to sharpen without increasing noise and artifacts. So, let's get started.

1 way:

1. Open our image. Immediately transfer it to Lab mode Image-Mode-Lab(Image-Mode-Lab).

2. Choose a palette Channels(Channels) , press CTRL+1 to select a channel Brightness(Lightness), then ~ to see the image in color.

3. Apply to this channel Filter-Sharpness-Sharpening(Filter-Sharpen-Unsharp Mask).

Settings vary by image. Many do not know how to use this filter correctly. Now we will correct this gap in knowledge.
So the first thing to do is to set the value Effect(Amount) within 80 - 150, depending on the resolution of the image. Then gradually increase the values Radius(Radius) until visible flaws and artifacts appear. Next, increase the value threshold(Threshold) until the roughness data disappears, but the effect of sharpening the contours is preserved.

4. Press CTRL+ ~ to select the composite channel. Then, as in step 1, we convert the image back to RGB mode.

2 way:

1. Open the image. Copy to a new layer CTRL+J.
2. Apply to this layer Filter-Others-Color contrast t (Filter-Other-High Pass), with a radius of about 1 (depends on the resolution of the image, but I don’t recommend setting it large, I’ll explain why later).

3. Click CTRL+SHIFT+U to desaturate the image. This is very important point! Since we have removed color information from this layer (which it certainly has, although the layer looks gray), this will avoid increasing color noise.

4. Change the layer blend mode to overlap(Overlay). You can do this in the Layers palette, or by pressing SHIFT+ALT+O.

5. If the result does not suit you, for example, the sharpness has increased too much, you need to reduce the opacity of the layer. If you need to increase the effect, copy the layer right amount times (CTRL+J).

If you try to sharpen the sharpness immediately by setting great importance radius in step 2, this will degrade the image quality.

3 way: the same second, but adapted for scanned photos. I think many will appreciate its effectiveness. I don't include pictures to avoid repetition.

1. Open the image, copy it to a new layer.
2. Repeat step 2 from the previous method, but set the radius value much larger, from about 4 and higher, depending on the resolution.
3. Next, you need to blur the layer with Filter - Noise - Dust and scratches(Filter-Noise-Dust & Scratches) so as to remove the grain but leave the outlines of the images.
4. Then repeat steps 3-5 from the previous recipe.

In order not to waste time on performing these actions in the future, you can create actions, that is, operations, for each selected method.

In one of the following lessons, you will learn another way to sharpen. It is quite complicated, so I did not clutter up this lesson with its description.

I wish you creative success!

Is your photo lacking clarity? This is very easy to fix in the PhotoMASTER program! Read the article and learn about three ways to sharpen your photo with this photo editor.

Safe values ​​for the “Threshold” parameter are from 3 to 10. If it is equal to 0, then the changes will affect every pixel in the image, because of this, small defects will become more noticeable in the photo.

STEP 3. Add clarity to individual parts

Go to menu "Retouch" > "". Adjust brush size, opacity and feathering. Select a section of the photo to edit. Click on the "Sharpness" tab and adjust the settings. They are identical to those presented in the step above. Save the changes by clicking the "Apply" button.

Everyone at some point in time is faced with the effect of blurring while taking a photo. This happens when jerking the hand, shooting in the process of movement, long exposure. With the help of Photoshop, this defect can also be eliminated.

Not only beginners are trying to catch the perfect frame. Even experienced specialists in their field with the availability of specialized equipment are trying to focus, monitor exposure and photosensitivity.
Before the photo is printed, the frames are processed in the editor in order to eliminate the existing visual defects.

Today we will discuss how to remove blur in a photo in Photoshop and sharpen the image.

Processing includes:

color correction;
brightness setting;
sharpening in Photoshop;
photo size adjustment.

The recipe for solving the problem is simple: it is better not to change the proportions and size of the image, but it is worth working on sharpness.

In the case of uniform blurring, not very noticeable, use the tool "Sharpening". It is designed to correct sharpness and is located in the tab "Filters" Further "Sharpness" and look for the desired option there.

After selecting the desired option, you will see three sliders: Effect, Radius and Isohelia. The value that is most suitable in your case must be selected manually. For each image with different color characteristic these parameters are different and you can't do it automatically.

Effect is responsible for the strength of the filtration. By moving the slider, you can see that big values increase graininess, noise, and the minimum shift is almost not noticeable.

Radius responsible for the sharpness of the center point. As the radius decreases, the sharpness also decreases, but the naturalness is more accurate.

The filtration strength and radius must be set first. Adjust the values ​​as much as possible, but consider the noise. They must be weak.

isohelia reflects the breakdown by color levels for areas with different contrast.
As the levels increase, the photo quality will improve. Thanks to this option, the existing noise, graininess are eliminated. Therefore, it is recommended to perform it last.

Option Color Contrast

Photoshop has an option "Colour contrast", responsible for fine-tuning the sharpness.

Don't forget about layers. With their help, not only photographic defects are removed. They allow you to accurately improve the quality of the object. The sequence of actions is as follows:

1. Open the image and copy it to a new layer (menu "Layers - Duplicate Layer", do not change anything in the settings).

2. Check on the panel whether you are really working in the created layer. Select the line where the name of the created layer is indicated and there should be a copied object.

3. Perform a sequence of actions "Filter - Other - Color Contrast", which will provide a contrast map.

4. In the area that opens, put the number of the radius of the area you are working on. Usually desired value is within less than 10 pixels.

5. Photo may contain scratches, noise due to damaged optical part of the device. To do this, select in the Filters "Noise - Dust and Scratches".

Good day to all, dear friends. I am with you again, Dmitry Kostin. And today we will photoshop again. Does it happen to you that you took several photos, but in the end it turned out that they are blurry and even a little blurry, and they already look somehow wrong? I guess it happened.

But thanks to our program, this can be fixed. Therefore, today I will tell you how to improve the sharpness of a photo in Photoshop. And already by tradition, I will show here several ways how this can be done.

Sharpen tool

The first thing that comes to mind in this case is to use the sharpen tool. So open the image in Photoshop and we'll get started. I took this picture. She's perfect for us.

To be honest with you, I don't use this method. I prefer the method below.

Sharpen filter

In addition to the usual tool, there is a whole group of filters specially tailored to our current needs. To do this, select "Filters" in the top menu and select "Sharpness". There you will see another submenu with several items. Let's consider a few of them.

Well, no matter which filter you use, the image is still clearly better and much more pleasant to look at.

In principle, such chips can be used to make your image clearer and better. And which way do you prefer? Or maybe you use something else altogether? Please write in the comments.

Well, if you want to master all the tools of Photoshop, know what for what and how to use it, learn to swim in it like a fish in water, then I recommend that you check out one great course. These videos are for all levels. The main thing is that after watching you will not have a mess in your head, since everything goes from beginning to end, from simple to complex. And the presentation of the lessons is just great, so be sure to check it out.

Then you will always be aware of everything important and interesting. You can also see other articles on my blog. I'm sure you'll find something of interest there. Good luck to you. Bye Bye!

Sincerely, Dmitry Kostin.

Sharpening and denoising are very important components in photo processing and can be applied to almost any image. And if there are feathers, fur or other microscopic details in the photo, then sharpening is a must. In this article, we will talk about the main ways to increase sharpness through Photoshop.

Our original image

We'll take a look at several sharpening techniques, but don't apply all of the techniques below to one image at once - experiment and find the one that works best for you.

To get a quality, sharp image, you need to consider both sides of the same coin. Strong sharpening through programs leads to the appearance of noise, while noise reduction makes photos more blurry. To achieve the optimal result, you need to find a certain balance so that the photos are sharp enough, but at the same time there is no excessive noise, which, of course, spoils the whole picture.

Our final image

Many images, such as our photo of a bird, contain areas that are initially sharp and blurry. We do not need to sharpen at all in those places where blurring, softness is provided. Take, for example, the green lawn in our photo, it serves as a beautiful backdrop, and there is no need to sharpen it at all. We'll show you how to apply sharpening only to areas where you really need it.

1. Open your image in Camera Raw

In Bridge, double-click the original image to launch Camera Raw. First, let's process the photo a bit, add contrast, increase the shadows, sharpen and saturate. For this photo, we selected the following settings for the above parameters: Contrast +15, Shadows +16, Clarity +10 and Saturation +18.

2. Maximize the sharpness

In the toolbar, select the tool Zoom (Magnifying glass) and zoom in on the image by 100%. Hold down the space bar and drag the image so that you can see both the bird's head and the background. Drag the sliders Amount (Number) and Radius (Radius) as much as possible to the right.

3. Now soften the effect

Now drag the Amount and Radius sliders back until the image looks natural. The Amount value is responsible for the sharpness of the entire image, and with the Radius value we determine how the sharpness affects its borders. Choose the optimal values ​​and do not forget to turn on and off the preview to compare the resulting image with the source. For our photo, values ​​of 67 for Amount and 1.4 for Radius are the most optimal.

4. Apply the mask

The Masking slider allows us to apply sharpening only to areas where there is any detail. Hold down the Alt key and move the slider. The image will be displayed in black and white. The further to the right you drag the slider, the more areas become black, which means that no sharpening will be applied to these areas. For this image, we chose a value of 40 to leave the initially blurred background untouched.

5. Convert the Image to a Smart Object

Open our photo in Photoshop by clicking on the Open Image button. Go to the layers panel, right-click on the background layer (Background layer) and select Convert to Smart Object (Convert to Smart Object). This will give us the opportunity to leave untouched the layer that is being edited, and all the applied filters will be added to it as points. If necessary, the settings of these filters can be changed later.

6. Use Smart Sharpen

In the CC's version of Photoshop, under smart sharpening(in English version Smart Sharpen) there is a slider responsible for reducing noise (Reduce noise). Together with the Amount and Radius settings, Smart Sharpen is a great tool for adjusting sharpness and noise. Start by changing the values ​​for Amount and Radius (Amount - 102%, Radius - 1.4px).

7. Reduce noise

Drag the noise reduction slider to the right to a value of 30 to remove the noise that has formed in the background of our photo. If noise is still noticeable, change the position of the Shadows slider to around 65%.

8. Use the Layer Mask

Zoom in to see the result of Smart Sharpen. In the eye area, the effect is too strong, noise is noticeable. To get rid of it, we arm ourselves with the Brush Tool, select the Smart Filters mask in the layers panel, change the brush color to black (you can use the D and X keys to change the brush color). And now on the layer with the filter we draw with a black brush the area where we want to get rid of noise, in our case it is the bird's eye.

9. Use Filters in Camera Raw

The background still looks too noisy. Let's try to reduce it further. Copy the layer with the key combination Ctrl / Cmd + J and go to Filter, select Camera Raw Filter. In the Camera Raw window that opens, increase the photo and in the Noise Reduction subsection (Noise suppression) move the slider Luminance (Glow) to about 46 until the graininess disappears from the light areas of the image.

On the bottom line of the layers panel, click on the icon Add layer mask (Add layer mask). In the toolbar, select the Brush and set the foreground color to black. Click on the mask and paint over the areas where you want to leave a high sharpness.

10. Sharpen tool

In the layers panel, click on the icon Create New Layer (Create a new layer) and rename the new layer to Sharpen tool. Then select from the toolbar sharpen tool Tool (Sharpness). In the top line of the tool options, check the boxes next to Sample All Layers and Protect Detail. Set the value Strenght (Intensity) to about 10%. Now we increase the image and with the help of this tool we draw all the details, the sharpness of which needs to be increased.

11. Correcting the colors

Now we will improve the color saturation a bit using Color lab. But first, let's combine all the resulting layers, for this, use the key combination Ctrl / Cmd + Shift + Alt + E. Rename the layer to Color boost and convert it to a Smart Object. Now double click on the layer to open it in a new document.

12. Saturate

Open the tab Image (Image) - Mode (Mode) and select Color LAB. Create a new adjustment layer Levels (Levels). In the settings of the adjustment layer in the drop-down menu, select A. To increase the saturation, we need to bring the white and black sliders to approximately equal values. Let's start by setting the value of 25 in the lower left window, which is responsible for the shadows.

13. Set values ​​for Levels

Now that we've moved the left slider to 25, we need to set the right slider to the same value (255 - 25 = 230). In the lower right box, enter the value 230. Pay attention to the red and orange fragments of the photo, they have become much more saturated.

14. Channel B

Open the channels drop-down menu again and change A to B. In this channel, we also need to bring the sliders to approximately the same values. But don't forget that channel B is responsible for the green tones, and we don't need to make the background too saturated. For this reason, we enter the following values ​​in the windows: 15 and 240.

15. Evaluate the colors of a photo

To evaluate the changes made, turn off the visibility of the layer by clicking on the eye icon next to the Levels layer. If the photo turned out to be oversaturated, reduce the transparency of the layer (Opacity) to 80%.

Now the colors look much better, but some of the yellow fragments have taken on a red tint as a result of our manipulations. To get rid of it, create a Layer mask (Layer mask) and with a black brush paint over the areas where we need to reduce the effect.

17. Add a Vignette

And finally, to soften the background a bit, let's add a vignette. Using the key combination Ctrl / Cmd + Shift + Alt + E, merge the layers, transfer the layer to a Smart Object and select Camera Raw in the Filters tab. Here we will use the Radial Filter. Select it and place the filter circle over the bird, set the exposure to -0.40, now click OK and save the image.
