Photoshop photos Blur Clear Daquan

Old have encountered blurred picture problem, yesterday in the search for solutions when I encountered this article, I feel very good, can really let blurred photos become clear, and more than one method.

One, sharpening smear repair method Local repair blurred image, it is often used to repair the face of the characters

1. Select the Sharpening tool in the Toolbox.

2. Set the pen decoration properties of the sharpening tool in the property bar. Set the brush to a softer pen and drag the slider to reduce the strength.

Tip: Use a soft brush to smear, will not appear blunt edge, low intensity repeated smear a bit similar to the painting in the rendering techniques, can make the modified part and the surrounding has excellent transition, do not see the repair traces.

3. Set the pen as the appropriate size. Smear in the eye area, you can see, the pen in place, the image will slowly become clear up, we slowly coated, so that its clarity to achieve the ideal can, do not overdo it, it will appear unsightly noise and spots.

The whole sharpening of slight fuzzy USM

Using sharpening tools, the advantage is that you can sharpen as needed, if you want to quickly repair the entire photo, it is too much trouble, then try the "USM Sharpening" filter, which is designed for blurred photos of a filter, suitable for the entire picture to adjust.

Use the menu "filter → sharpen →usm" pop-up sharpening dialog box, in this example we set a large number of values to achieve a clearer effect, a smaller radius to prevent loss of image quality, the minimum threshold to determine the edge area to sharpen.

Tip: The quantity Value control the degree of sharpening, the higher the number, the clearer the image, but not the higher the number of better, too high a number of images will increase the clutter, affect the quality. The RADIUS value is used to set the affected pixel range, that is, the specified edge of a large range of pixels are adjusted, if the radius is high, the picture will appear a large area of light and dark, loss of detail. The threshold value is used to determine how much of the sharpness pixels must differ from the surrounding area before being filtered as edge pixels and sharpened, the image is softer when the values are high, and the image is sharper when the value is low. When you adjust these values, you should observe more and take the most appropriate values.

Third, strengthen the repair, superposition edge method Sharpening

Both methods are conventional tips, and if you want to make your photos clearer and better, you'll need to use high contrast to keep the filters and layer blending mode in the two magic.

1. Open the blurry photo, press "ctrl+j" shortcut key, copy layer to layer. Then press "shift+ctrl+u" shortcut keys to color the image. We'll use this black and white layer to harden the edges.

2. Use the "filter → other → High contrast" menu to pop up the High Contrast Reservation dialog box and set the value to "0.9". Click OK.

3. Set layer blending mode to "overlay", Press "ctrl+j" shortcut key copy layer, if the image also has fuzzy phenomenon, you can duplicate several layers superimposed on the top.

Hint: The image is not all evenly balanced, in the repair, some areas may be overdone, resulting in miscellaneous spots. We can erase the superimposed image by using an eraser.

Four, Super Magic weapon--topaz filter

If you are not satisfied with the above three ways, then I give you a super magic weapon--topaz. This is a very good clear filter, it can not only apply to blur the image of the field of clarity, but also for the art of image processing. It and Photoshop with the sharpening filter to calculate the different way, you can calculate a very beautiful hand-painted effect, very suitable for hair, plant images of the clarity and artistry.

After installing the Topaz plug-in filter, we open a picture, use the menu "filter →topaz Vivacity→topaz sharpen", and in the Main tab, set a sharp value of "1.9".

In the Advanced tab, set the linear feature to "0.84", you can see that the details of the hair in the image immediately become very clear, and the art of processing, just like with a tick strokes out of the same pen. Using this feature, we can make the effect of the shot.

Private Secrets: Master The above methods, in addition to easily put some of the camera because the lens is not allowed to restore clarity, the application of Topaz filter can also be used to adjust the cell phone shot low-resolution photos, so that it can also achieve clear results. But it is helpless for some of the ghosting caused by the shaking of the hand. Interested friends can try the "smudge tool" to smear the ghosting part of the photo, perhaps also to achieve a certain repair function.

Five, the picture becomes clear tutorial.

1. Open a blurry picture

2. Select Channel-----red channel

3. Copy Red Channel

4. Perform filters--stylized---illuminate edges (I use the value is edge width 1; brightness 20; smoothness 3) 5. Perform filters-blur-high rip blur (I use RADIUS 2)

6. Color levels (I use the value 17 1.00 169)

7. Load the red copy channel into the selection, go back to the layers panel, and then copy the layer

8. Selection Filter---Artistic effect---painting (brush size 1 Sharpening 25)

9. Duplicate another layer so that the opacity is 30 below the copy layer

10. The selected copy layer mode should be color filter

11. The cancellation of the election completed

Six, the larger picture, although the high precision, sometimes poor care, will be the whole of noise, but others PS can not recruit it, you can use a mixed method to sharpen, will be able to reduce noise, so that you sharpen more refined.

Method one, using the fade command:

The first step is to open the image you want to sharpen.

The second step, copy a layer, the original tutu layer of small eyes close, the figure to enlarge to 100%.

The third step, through the "filter" in the "sharpening", which is all right, I still use "USM sharpening." (High contrast keep with this FBI noise)

The fourth step, after USM, "Edit" menu appears a "Fade xxx" command or with the shortcut key "Shift+ctrl+f" (secretly told you, use the filter, the final use will appear after the fade, which can have other uses), open.

The fifth step, in the jump out of the "Fade" dialog box adjustment, "mode" select "Brightness", the author of the Opacity to 90 (according to your film situation).

Sixth Step, Save!

Method Two, use Lab brightness channel

This method only to the image Mingdouri color has no effect, you say high, not high, how can noise is not low.

The first step, how to put the picture into the do not say, according to the above one or two do;

In the second step, open the Image menu, select Lab Color in "mode", and jump out of the dialog box to "Do not merge";

The third step, in the "Layers" Panel point "Channel" tab, and then point "lightness";

The fourth step, open the "Filter" menu, "sharpening"-"USM Sharpening";

The fifth step, then to the "layers" panel, the lab channel's eyes lit;

The sixth step, must be whole, open the "Image" menu, choose "Mode" in the RGB color, pop-up dialog box point "Do not merge", the map back to RGB.

Use filters to optimize images

First, hit the Kaiyuan diagram, double-click Unlock.

Second, ctrl+j create a copy of good habits. Select brightness for Copy mode

Third, select the "-USM sharpening" command under the Filter menu, adjust the sharpening parameter in the setting window, adjust it according to the fuzzy situation of your original image, use the sharpening quantity as "150%", the radius is "1" pixel, the valve value is unchanged.

Four, after the third step, for the picture clear basically made a foundation. Then select the Mode-lab color command under the Image menu and select the Flatten layer in the pop-up window to determine.

Five, in lab mode, create a copy again.

In the channels panel, see the "lightness" channel on the Layer channel, select the channel, and then use the "Sharpen-USM" command on the filter menu to sharpen the channel by setting the sharpening parameters. This figure is set out below.

Seven, return to the Layers panel, the copy layer mode modified to "soft light", adjust the transparency of 30%. Look at the image at this time not only more clear picture, color is more gorgeous. (This can be based on their own photos and additions)

PS will blur picture clear essentials

Although the digital camera often has sharpening function, but we recommend using PS based on the actual situation of the photos to determine the edge details and texture sharpening effect.

When we are shooting, we will encounter problems such as motion of the subject, camera vibration or slight focus, etc., after the shooting may face some personality characteristics of each camera, such as Canon, Fuji Machine General photo image is soft, This time we would like to have a magic button to allow us in the later image processing simple click can solve all the problems, and even many people believe that there is a "panacea", called "sharpening."

This concept is not correct. Sharpening may correct these problems, but it was originally designed to solve the digital problem--converting the image on a scene or film from a continuous-tone region into a specific-tone small square. In the case of DC, when capturing images digitally, if the detail lines coincide with the elements of the CCD, they may be too small to be recorded by the CCD into the corresponding pixel. To avoid this, the DC is virtualized so that the details (lines) can be recorded across several pixels. The details of this partial blur are actually "hidden", sharpening the details by increasing the contrast between adjacent pixels. If the details (lines) are smeared over 4 pixels, sharpening creates a clear image edge by increasing the contrast between adjacent pixels.

While digital cameras tend to sharpen this option, we recommend that you adjust the pixel, based on the actual situation of the image to determine the edge details and texture sharpening effect, while the best note is the end of the photo processing to sharpen, not the beginning and the middle.

In addition, we must note that JPEG is a lossy compression format, so it is a good idea to convert the image to a lossless picture format before it is processed. This is often the first step in the post-processing of the photography masters, the JPEG converted to the TIFF format before processing, especially to avoid repeated use of the same picture in the JPEG format repeatedly, if you really want to save also use the Save as ... Command.

If you simply use the sharpen (sharpen) filter in PS and simply repeat it 5 times, you will get the following photo. The fact is, the sharpening filter is a blunt tool, sharpen more (sharpen) filters are similar, in addition to saving the number of repetitions can not see more use.

Sharpen edges edge filter is slightly stronger than the first two, but still lacks flexibility, if used heavily, it can easily result in image pixel, white edge effect. The tool chooses before raising the contrast to find pixels whose image is large and the gap between adjacent pixels is significant. The difficulty is that the program often does not correctly identify the edges where if you shoot a clear object in front of a simple figure, this filter works fine. But if there are more details and the skin tone contains more contrasting pixels than you think, this is the sharpness of the edge filter is "reluctant".

Unsharp Mask (USM) sharpening filter is a common and almost universal tool because it can quantify the degree of sharpening, quantity, radius, and threshold in 3 ways.

The Blur mask sharpening process (Unsharp MASKING,USM) in Photoshop provides three kinds of control parameters:

Quantity (Amout): Controls the intensity of the sharpening effect. For general processing, the setting of the number 150 radius 1 level 2 is a good start and then properly adjusted as needed. An image with a large amount of value will become false.

Radius: Used to determine the width of the pixel points that are highlighted as edges. If the RADIUS value is 1, the entire width from light to dark is two pixels, and if the radius value is 2, there are two pixel points on each side of the edge, then the entire width from light to dark is 4 pixels. The larger the radius, the clearer the details, but the glow will also occur. Professional designers are generally willing to use the USM sharpening more than once to sharpen the radius set more than 1 pixels.

Threshold (Threshold): Determines the contrast of the adjacent pixel boundary can be sharpened, and below this contrast value does not sharpen. The setting of the threshold is the key parameter to avoid problems such as spots and pitting caused by sharpening processing, and the correct setting can make the image perfect for both maintaining a smooth natural hue (for example, the pure blue sky in the background) and emphasizing the contrast of change details. In general prepress processing we recommend a value of 3 to 4, more than 10 is not desirable, they will reduce the sharpness of the processing and make the image look very ugly.

Although the use of default parameters has been able to get a good sharpening effect, but more than a comparison, according to the actual situation to set a reasonable sharpening parameters are always needed, so that can better reproduce the image details, and not to create new trouble: such as spots and pitting.

Generally for portrait, you need the number of filial piety radius wide, valve value high parameters, commonly used is 71/17/17 this set of parameters. For landscape images with a lot of detail, you need a high number of parameters that are low in the radius of the value, such as 200/2/2.

These parameter settings, although often used but not absolute, need to be adjusted to suit your needs. If you overdo it, you'll see a halo on the edge of the object, like a torch to draw a circle of edges around the character. If you continue sharpening, the whole picture will be pixel-wide.

If you need fast, high-volume processing (equivalent to sharpen command) scenery, you can set the number to 80, radius set to 2.2 pixels, low threshold. Sharpening portrait can set the threshold to 10.

In the PAA provides a number of action for sharpening the action, they have ingenious different, we can try more, but the basic use of USM sharpening filter. Here gives the "sharpening-lab method" some detailed instructions.

Sharpening Lab Method

This action is used in the processing of daily Photoshop sharpening the common skills, is the first RGB image through the image?? Mode command into lab mode, and then in the channel panel, select the Brightness (lightress) channel, sharpen with the USM sharpening filter, and then convert back to RGB mode. The advantage of this is to avoid the dispersion problem that occurs at the edge of the sharpening object.

The default parameter setting for the USM Sharpening dialog box (brightness channel's image is grayscale display)

Have you noticed that the image in this dialog box is black and white, that's right!

Below we give some other commonly used USM sharpening parameters for your reference:

Quantity 150%, radius 3 pixel, Valve value 1 color order, suitable for softer image (portrait or flower).

Quantity 85%, radius 1 pixel, valve value 4 color order, suitable for most cases.

Quantity 65%, radius 3 pixel, Valve value 2 color order or quantity 65%, radius 4 pixel, valve value 3 levels, sharp effect, the application subject has sharp edge, such as buildings, coins, automobiles, or the photo itself is relatively vague.

Here's another trick is to apply the "Fade" menu command, you can get the effect, such as sharpening after the discovery of a bit, then you can use this command to fade some, this percentage you can decide.

The introduction of four tools, in fact, sharpening process is a control of the contrast process, so the most effective choice of sharpening method is to apply the layer + High contrast retention filter. First copy a layer, then the copy layer with the "High Contrast" filter, and then adjust the overlay of the layer, such as a strong color, you can use "strong light", to sharpen some with "soft light", to a stronger effect with "light" mode.

There are also some techniques for using masks or sharpening local areas with a selection. Here is the unknown, the specific steps are similar.

The last method is easy to ignore, that is, in order to sharpen the subject, we can virtual non-principal. such as the red flowers in the green leaves, after sharpening the whole picture, we can virtual green leaves (with fuzzy tools), when the red flower looks more beautiful.

In addition, sometimes it is also a good choice to sharpen the sharpening brush with PS.
