We are constantly photographing - our children, family and friends, nature, pets. Sometimes the quality of our photographs doesn't quite suit us, and sometimes it just makes us sad. Therefore, the question - how to improve the quality of photography is by no means idle, but very urgent.

Corel Photo-Paint has a great plug-in - simple and intuitive - Image Adjustment Lab.

This plugin transforms the photo.

In this tutorial, we will be improving the quality of our original photo. Let's make it more contrasting, saturated.

Let's prepare our photo for further graphic work with her. For example, in order to insert your photo into a ready-made frame template.

So. Let's open the Corel Photo-Paint program starting with version X3. Let's open our photo that we want to improve.

On the Menu Bar, find the command - Settings.

And then in open tab let's select this plugin - Image Adjustment Lab.

Here's what we'll see:

We have two photos in the viewport - one - The original, the other is Working view- the results of our color correction will be visible on it.

Let's take a closer look at the top panel in the Laboratory window.

1. Rotate photo 90 degrees counterclockwise.

2. Rotate photo 90 degrees clockwise.

3. Panorama allows move the image in the Source Photo window.

4. Enlarge photo- or from the keyboard - F2

5. Reduce photo or from the keyboard - F3

6. Photo display Fit to Original Window or F4.

7. True 100% display Photo.

8. One viewport- Working viewing. There is no original window in this option.

9. View in two windows- original photo and Working preview.

10. Split View - in one window Original photo and Working preview. You can move the image dividing line arbitrarily.

Let's go back to our original image.

We pressed the button - Take Snapshot and Auto Adjust.

Let's analyze in detail operating buttons in the Laboratories window:

1. Take a snapshot. Be sure to release this button before editing to save the initial version of the photo, and then release it every time we make any noticeable changes to the photo.

2. Auto-tuning. Corrects the color and tone of the image using standard automatic functions.

3. Reset to original state. There are times when the result from Auto Adjust does not suit us or we did not save the original photo, and the final result is not satisfactory.

4. Tab - Saved options appears after we release the button - Create snapshot... Here are the thumbnails of the image that we edit and save.

Click on any thumbnail - and this selected image will appear in the Work View window.

Why do we save different variants editing?

To choose the most suitable option Images.

Summarize. Often, the quality of a photo can be improved with the help of Autotuning.

And if you want more?

Now let's look at the right tab in the Labs window.

Here we can manually adjust changes in color, tone, saturation, brightness and other parameters that improve photography.

Just move the slider in the parameters graph. And the result will be reflected immediately in the Work Viewer.

Often times, the composition requires some kind of stylized photographs.

If our image requires a certain color tone, then we can add new colors to it, or, conversely, reduce and muffle the colors.

We will first reduce - Saturation. Move the slider to the left.

Then let's move a little Temperature slider towards orange.

Let's add brightness and contrast to the photo. Move the runners a little to the right side.

And we constantly see and control the changes in the photo. in the Work Viewer.

Let's increase a little Intermediate tones.

Let's keep this option.

In the other two versions, we can experiment with different color tones.

Axis - Hue- first, move the slider to the left to the pink color.

We will get a photo in pale purple tones. Let's save this option - the button - Take a snapshot.

And in this case, the slider Shade we have strongly left to the right. Let's also keep this style of the photo.

The next option is almost discolored, but not to a gray tint, but rather in a sepia style. We save.

Here we still return to our version, which we received from Autotuning.

Just click on the thumbnail, which is the second in a row after the saved source.

A little add this version of the photo brightness, contrast.
Temperature and saturation subtract slightly.

Now we can choose a photo option whichever suits us best. Open the thumbnails and look in the Working Viewer.

When we release the OK button, then the image that is in the Working View window will be saved.

After this practical lesson, you yourself will boldly choose the desired brightness and tonality for your photo.

Posted on 02/14/2012 09:34 AM Paint Shop Pro X4 provides ways to adjust brightness as well as contrast in your images that create differences between light and dark pixels in an image. By applying commands to a selection or the entire image, you can do the following:

manually define brightness and contrast;

setting individual brightness in the image;

defining light (75% hue), medium (50% hue) tones and shadows (25% hue) to ensure smooth transitions between them;

distribute pixel brightness values ​​more evenly from black to white;

increasing the overall contrast when the histogram does not cover the entire brightness spectrum;

determine the settings for brightness, contrast and gamma on the image;

creating a pure black and white image.

7.3.1. Adjusting the light, medium, and dark tones in the image

The command Adjust → Brightness and Contrast→ Highlight / Midtone / Shadow(Adjust → Brightness and Contrast → Highlights / Midtones / Shadows). After executing this command, a dialog box opens. Highlight / Midtone /Shadow(Highlights / Midtones / Shadows) (Fig. 245).

If nothing is selected in the image, then the adjustment is carried out for the entire image.

Rice. 245. Image tone adjustment

Options Shadow(Shadow), Midtone(Intermediate tone) and Highlight(Flare) defines the values ​​for shadows, mid-tones and highlights in the selection, and if nothing is selected in the image, then for the entire image. Numerical values in these parameters depend on the selected position of the switch located below these parameters.

The switch at the bottom of the dialog box can take the following positions:

Absolute adjustmentmethod(Absolute Adjustment Method) - Sets the positions to 25% for shadows, 50% for midtones, and 75% for highlights. Typical values ​​are around 35 for shadows, 50 for midtones, and 65 for highlights, but these may vary depending on specific photographs. Increasing values ​​lighten the area, while decreasing values ​​darken it.

Relative adjustmentmethod(Relative Adjustment Method) - Adjusts the brightness levels relative to their original states. Positive values ​​lighten the area, while negative values ​​darken the area.

7.3.2. Setting bar graph

The Tone Histogram allows you to analyze the tonal range of an image and redistribute the balance of shadows, mid-tones, and highlights.

To correct tones in an image or selection, you must run the command Adjust → Brightness and Contrast→ Histogram Adjustment(Adjust → Brightness and Contrast → Histogram Adjustment). After executing this command, a dialog box opens. Histogram Adjustment(Histogram correction) (Fig. 246).

Rice. 246. Setting the histogram

Switch Edit(Change) defines the type of the edited histogram:

Luminance(Luminance) - allows you to edit the histogram based on the brightness of the image;

Color(Colors) - allows you to edit the histogram based on one of the image color channels. After selecting this position of the switch, a list becomes available to the right of this position, in which you need to select a color channel, on the basis of which the active image will be edited.

In the list Presets(Options) offers ready-made correction options. When you select any of them, the switch Edit(Change) automatically resets to position Luminance(Illumination). Preset value Default(Default) does not represent any additional installations in the image.

In the parameters below the graph, you can change the values, both with the help of absolute values, and with the help of relative (percentage) values.

Slider Low(Low) starts on the left side of the histogram, is located between the left edge of the graph and the point where the curve starts to rise. This gap indicates that the dark pixels in the image are not completely black. This parameter displays the percentage of pixels that are between zero and low values ​​- their contrast will be lost. As a general rule, set the low level to less than 0.1%. This parameter can also be adjusted using the dark gray slider.

Slider High(High) starts on the right side of the histogram, is located between the right edge of the graph and the point where the graph is reduced to zero pixels. This option changes the light pixels in the image to white. As a general rule, set this parameter less than 0.1%. This parameter can also be adjusted using the white slider.

Slider Gamma(Gamma) - If the overall image is too dark or too light, then you need to adjust the gamma, which is the standard measure for changing the contrast in images. If the image is too dark, then move the slider Gamma(gray triangle) to the right to increase the gamma. If the image is too light, then move the slider Gamma left to decrease the gamma setting.

Slider Midtones(Midtones) (on the right side of the window) - if the graph has peaks on the left and right, or contains low values ​​in the center, then the midtones must be compressed. Shadows and highlights should be expanded to show the information they contain. This often happens in flash photography when the subject is too close to the camera; the subject appears brightly lit, but the background of the photo appears dark. To compress the midtones, move the vertical slider Midtones... If the peaks of the graph are in the center and have a low number of pixels on the left and right sides, then widen the midtones by moving the slider Midtones way down.

If you are creating artistic effects, then you can use the controls Output Max(Output max) () and Output Min(Min display) () to the left of the histogram. Engine Max is a white circle on a gray background, and the engine Min is a black circle on a gray background. In order to darken the light pixels in the image, you need to move the slider Max way down. In order to lighten dark pixels in the image, you need to move the slider Min up.

Even if the sliders move along the vertical axis, the parameters Max and Min(ranging from 0 to 255) affect the horizontal axis. All pixels outside the range are converted to be within the range.

If you just want to enhance your image, then you do not need to use this parameter.

Triangular buttons under the slider Gamma(Gamma) define the scale of the histogram and nothing else. Left button zooms in, and the right button zooms out the histogram. Button 1: 1 sets 100% scale of the histogram.

Adjusting the brightness and contrast of the picture

Advice: If you are using PowerPoint, you can still keep the original version of the picture, even if you changed the brightness of the picture. This feature is not available in Word and Excel.

For full-fledged work with images in Microsoft Word 2010, you need to learn how to work with the color settings of the image. It will be helpful to know how to apply artistic effects to a drawing that can significantly improve appearance Images. This is outlined in this article with illustrative examples.

Adjusting the brightness and contrast of the image

Adjusting the brightness of an image involves lightening or darkening the image. When using these customization tools, Word program 2010 automatically makes changes to the range of colors. That is, adjusting the brightness for shadows, highlights and midtones is not available. In simple terms, the setting is used using special templates that have different degrees of exposure. Exposure, in turn, determines the amount of lightening / darkening.

Contrast is the ratio of the lightest to darkest areas of an image. In color contrast, it is the difference in color shades. In Word 2010, brightness and contrast are controlled by the same templates. In turn, templates can have zero values brightness or contrast, which allows you to separately adjust the level of their values. When fine tuning("Picture format" window), the situation is similar.

To adjust the brightness and contrast of the image, do the following:

1st method.

1. Highlight the image in Word document 2010 and go to the Format tab.
2. In the "Change" group, click on the "Correction" button and in the window that opens, select the desired brightness value from the collection of samples. If you need more fine tuning, click on the "Picture Correction Options" button. The "Format" window opens on the "Picture Settings" tab.
3. In the "Brightness" area, set the desired value (as a percentage) and click "Close".

2nd way.

1. Click on the image in the Word 2010 window and in context menu select "Picture Format".
2. Click on the "Picture Adjustment" tab and set the desired brightness values.

Sharpness is changed in the same way. Reducing sharpness results in a blurred image, while sharpening, on the contrary, increases the clarity of the image. However, this will lose smooth transitions in the image and increase its graininess.

Figure 1. Correction of sharpness, brightness and contrast

Color adjustment of the image

Color adjustment of the image allows by means of Word 2010 carry out color adjustments in terms of brightness, contrast, sharpness and saturation. By simple manipulations, you can set the image to look appropriate for the tasks.

Changing color saturation

Color saturation is the strength, intensity of the perceived color tone. In other words, it is how strongly a particular color is represented in the palette, and how "pure" it is. "Pure" color means the minimum presence of pixels of other colors, their shades, as well as shades of the base color. Saturation refers to what a particular color looks like under varying degrees of light. The saturation, or intensity of a color, varies with the strength of the light. That is, the brighter the picture, the brighter and more saturated the colors in it - and this rule applies even to black and its shades. Without going into the details of color theory, we note that by changing the color saturation, you can radically change the appearance of the entire image. Since with a change in the saturation of colors, the composition of the color palette of the image completely changes.

To color adjust the image, follow these steps:

1. Select the picture you want in your Word 2010 document.
2. Click the Format tab and in the Modify group click the Color button
3. In the window that opens, in the Color Saturation group, select the appropriate swatch.

For more fine-tuning, follow these steps:

1st method.

1. Right-click on the required picture and select Format Picture from the context menu.
2. Click on the "Image Settings" tab in the "Image Format" window that opens, go to the "Color Saturation" group.

2nd way.

1. Click the Color button and in the window that opens, click Picture Color Options.
2. Use the Presets and Saturation areas in the Color Saturation group to set the options you want.

Figure 2. Image color settings

Color shade

Changing the color tint allows you to lower or raise the “temperature” of an image. Simply put, decrease or increase the saturation of warm or cold shades of a color. An example of warm colors are shades of red, yellow, orange, and cold colors are shades of blue, turquoise, and gray.

To change the color tint of a picture, follow these steps:

1. Click the Format tab, and in the Modify group, click the Color button.
2. In the window that opens, go to the "Color Tone" group and select one of the swatches.

For more fine-tuning, go to the "Picture Format" window and set the desired values ​​in the "Color Tone" group.

Image recoloring

If you want to completely recolor the image, that is, give it a certain color ( color scheme), do the following:

1st method.

1. On the Format tab, in the Modify group, click the Color button.
2. In the window that opens, go to the "Recolor" group and select one of the swatches.

2nd way.

1. In the Picture Format window, click the Picture Color tab.
2. In the "Recolor" group, click the "Recolor" button in the "Presets" area, and in the window that opens, select the appropriate swatch.

Artistic drawing effects

With the help of artistic effects, you can significantly improve the appearance of an image without resorting to the help of special graphic editors. A total of 23 effect patterns are available. Unfortunately, working with layers is not available.

To give your drawing an artistic effect, do the following:

1st method.

1. In the window open document click on the desired image.
2. Go to the "Format" tab in the "Change" group and click on the "Artistic Effects" button.
3. In the window that opens, select the appropriate sample.

2nd way.

1. Right-click on the picture and select Format Picture from the context menu.
2. In the window that opens, open the "Artistic Effects" tab, then click on the "Artistic Effects" button to select the appropriate sample.

Figure 3. Artistic effects

Use the Opacity and Size options for the artistic effects to make more detailed adjustments.

• Transparency - allows you to adjust the transparency level of the applied effect. The more transparency, the less changes made to the picture when the effect is applied will be reflected, and vice versa.
• "Size" - determines the "density" of the applied effect. So for the "Watercolor" effect, this is the size of the brush, for the " Light screen"Is the size of the grid, and so on. The lower the value, the more accurate the changes made, and vice versa - it all depends on what kind of picture you want to set.

Note that adjustments are only available after applying an effect to a picture.

Individual color pixel transparency

To give an image a special effect, you can “desaturate” pixels of a specific color. A similar approach can be used, for example, if you want part of the text to show through the picture.

To set the transparency of pixels of a specific color:

1. Click "Set transparent color" in the window for changing the color of the picture - the cursor will change to a pencil with an arrow.
2. Select the area of ​​the image with the required color and left-click - the pixels of the specified color will become completely transparent.

Conclusion

At this stage in the development of Word 2010, you need to be able to change the image in terms of color saturation, brightness, contrast, etc. This will allow you to quickly and efficiently adjust the image without resorting to the help of specialized graphic editors. Fortunately, the possibilities for working with images in Word 2010 are now more than enough that they can be compared in scale with some graphic editors... But, even if you are not faced with the task of becoming a specialist in graphics processing, you need to know the basic concepts. Actually, the main ways of adjusting images have been outlined in this article.

Color selection

The active brush color (foreground color) is changed by clicking the left mouse button, the active background color is changed by clicking the right mouse button.

Lines, curves, contours of shapes are drawn with the color of the brush, and also fill, spray, brush, pencil work in this color. The shape's cavities are painted with the background color. The eraser leaves the background color behind when erasing the drawing.

Color change

The color panel contains 28 paints. If necessary, you can replace the color in the palette with another: double-click on the color to be replaced or Palette - "Change palette", then in the "Change palette" window - select the desired color (out of 48 colors).

The computer allows you to work with millions of colors. Therefore, if you need a color that is not there, you can create it yourself - the command "Define color"

In addition to the "manual" selection, the color can be determined by its code - "Hue, Contrast, Brightness" or "Red, Green, Blue".

After setting the color, you can add it to the set of additional colors or change it in the palette (OK)

Quest "Coloring"

1. Start Paint. Set the sheet size to 585 x 640.

2. Insert a picture from the file "pictures \ hare.bmp" (Edit - Paste from File)

3. Using RGB color codes, color the picture according to the sample. Try to paint over the outlines of the areas as well. One way is to paint the area first with black, then with the desired color. Another way is to set the desired color with the background color, black with the brush color and using a colored eraser (i.e. holding right button mouse), replace the color.

4. Save the picture in your folder under the name "2-hare.bmp"

5. Create a new picture (File - New)

6. Insert a picture from the file "pictures \ birdie.bmp"

7. Color it as you wish and save it in your folder under the name "2-bird.bmp"
