Adjusting the Brightness and Contrast of a Picture

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

Color selection

The active color of the brush (base 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 figures are drawn with the color of the brush, and fill, spray, brush, pencil work in this color. The cavities of the figures are painted with the background color. The eraser, erasing the drawing, leaves behind the background color.

Color change

28 paints are placed on the color panel. If necessary, you can replace the color in the palette with another one: 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 does not exist, you can create it yourself - the "Define Color" command

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)

Task "Coloring"

1. Launch 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 the RGB color codes, color the picture according to the pattern. Try to paint over the contours of the areas as well. One way is to paint over the area first with black, then with the desired color. Another way is to set the desired color as the background color, black as the brush color, and using the colored eraser (ie holding the right mouse button), replace the color.

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

5. Create a new drawing (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"

The Adjustments menu in Paint.NET contains various commands for adjusting the color content of an image. There may be more commands in this menu depending on the number of external Paint.NET plugins connected. The image below shows a minimal view of the Adjustments menu as it appears in a freshly installed Paint.NET editor.

To illustrate the effect of each command from the "Correction" menu item, we will use the image below. This is the original image. In the description of most of the commands on this page, an example will be given - a drawing obtained from the original one by applying one or another Paint.NET command from the "Correction" menu.

Auto-align color levels in Paint.NET

Menu item "Auto leveling" in the "Correction" menu of the graphic editor Paint.NET is designed to align the color of the image. Too dark or, conversely, too bright parts of the image will be displayed in the normal range. This command has no parameters. The result after applying level alignment to the original image can be seen in the figure below. This command is equivalent to the Levels adjustment with default settings and the Auto Level button pressed.

Adjusting Image Brightness and Contrast in Paint.NET

Menu item "Brightness and Contrast" is designed to make the colors in the picture darker or lighter, or to make them more contrasting. The dialog box of this function has two parameters: "brightness" and "contrast", respectively.

This is what the original image will look like if we make it brighter.

This is what the original image will look like if we make it more contrast.

And this is how the original image will look like if you make it brighter and more contrast at the same time.

Image size to fit window in Paint.NET

Team "Fit to window" scales the image so that it fits completely into the workspace. This is useful for large images to see the entire picture. At the same time, the execution of this command does not increase the scale of the picture by more than 100%, which can be seen using it on a small image.

Adjusting Color Curves in Paint.NET

The "Curves" command is intended for visual color management in the form of curves. This menu item "Curves" is devoted to a separate page of the manual.

How to make an image black and white in Paint.NET

Menu item "Make Black and White" provides an easy way to reverse the colors in an image and make it black and white with gray tones. An example of applying this correction over the original image can be seen in the figure below.

Changing the Hue and Saturation of a Picture in Paint.NET

Team "Hue and Saturation" used to change the saturation of colors in an image or change their hue. In addition, using this command, you can also change the brightness of colors. However, it is to change the brightness that you should use the special command "Brightness and Contrast", described above, because. the result of using this function may be different.

If you apply the Hue and Saturation command to the original image? with the value of the "hue" parameter 88 and the parameter "saturation" 158, the result will be as in the figure below.

How to make a photo negative in Paint.NET

Team "Invert Colors" its action is similar to turning a photograph into a negative. This command reverses the colors. So, if you apply this command to the image twice, you will get the original image again. If we apply this command to the original image from our example, the result will be as shown in the figure below.

Gamma and color range of an image in Paint.NET

The "Levels" command is used to change the color gamut and range of colors in an image. A separate page is dedicated to the "Levels" command.

Roughening Image Colors in Paint.NET

The Roughen command lets you reduce the number of available colors used in an image. Typically, for each color channel: red, green, and blue, there are 256 possible values ​​(from 0 to 255). Using the Roughen command in Paint.NET, you can limit this value to between 2 and 64, per color channel. Reducing the number of colors gives the image the effect of an artificially aged or retro picture. Using the Roughen command for our example will give the following result.

How to make a sepia effect in Paint.NET

The Sepia command first converts the image to black and white and then adds a sepia tone. From history, one of the meanings of the term "sepia" is paint. Natural sepia was made from the ink sac of a cuttlefish. This paint was used by artists in the middle of the eighteenth century when drawing pictures. Natural sepia was used to tone photographs to brown. The effect of sepia in photography is the conversion of silver to sulfide, which becomes more resistant to fading. Therefore, many old black and white photographs are brown, so they have a better chance of not fading and surviving to this day. The application of the "Sepia" command to our example can be seen in the following figure.

To fully work with images in Microsoft Word 2010, you need to learn how to work with image color settings. It will be useful to know how to apply artistic effects to a drawing, which can significantly improve the appearance of the image. This is described in this article with illustrative examples.

Adjusting Image Brightness and Contrast

Adjusting the brightness of an image means lightening or darkening the image. When you use these adjustment tools, Word 2010 automatically makes changes to the color range. That is, adjusting the brightness for shadows, highlights and midtones is not available. Simply put, the setting is used using special patterns that have different degrees of exposure. Exposure, in turn, determines the degree of lightening/darkening.

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

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

1st way.

1. Select the image in your Word 2010 document and go to the "Format" tab.
2. In the "Edit" 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 the Picture Correction Options button. The Format window opens on the Picture Setup 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 select Picture Format from the context menu.
2. Go to the "Picture Adjustment" tab and set the desired brightness values.

Sharpness is changed in the same way. Decreasing sharpness results in blurry images, while sharpening, on the contrary, sharpens the image. However, the smooth transitions in the image are lost and graininess increases.

Figure 1. Correction of sharpness, brightness and contrast

Image Color Adjustment

Image color adjustment allows Word 2010 to adjust the color in terms of brightness, contrast, sharpness and saturation. By simple manipulations, you can set the image to look appropriate for the tasks.

Change color saturation

Color saturation is the strength, the intensity of the sensation of a color tone. In other words, it is how strongly a certain 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 main color. Saturation refers to how a particular color looks under different levels of light. Saturation, or the intensity of a color, varies with the intensity 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 drastically 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 an 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 sample.

For finer tuning, follow these steps:

1st way.

1. Right-click on the desired picture and select Picture Format from the context menu.
2. Click on the "Picture Settings" tab in the "Picture 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 hue allows you to lower or increase the "temperature" of the image. Simply put, reduce or increase the saturation of warm or cold shades of color. An example of warm colors are shades of red, yellow, orange, and cool colors are shades of blue, turquoise and gray.

To change the color hue of a picture, do the following:

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 in the "Color Tone" group, set the desired values.

Image recoloring

If you want to completely recolor an image, i.e. give it a specific color (color scheme), follow these steps:

1st way.

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 the image without resorting to special graphic editors. A total of 23 Effect Patterns are available. Unfortunately, working with layers is not available.

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

1st way.

1. In the open document window, click on the desired image.
2. Go to the "Format" tab in the "Edit" 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 swatch.

Figure 3. Artistic effects

For finer adjustments, use the Opacity and Size options for the Artistic Effects.

• "Transparency" - allows you to adjust the level of transparency of the applied effect. The greater the transparency, the less changes made to the picture when applying the effect 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" effect, this is the size of the grid, etc. The smaller the value, the more accurate the changes made and vice versa - it all depends on what kind of picture you want to set.

Please note that setting options is available only after applying the effect to the picture.

Transparency of individual color pixels

To give an image a special effect, you can "desaturate" pixels of a certain color. A similar approach can be used, for example, if you want to see part of the text 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 take the form of a pencil with an arrow.
2. Select a section of the image with the desired 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, contrast brightness, etc. This will allow you to quickly and accurately adjust the image without resorting to specialized graphic editors. Fortunately, there are more than enough opportunities for working with images in Word 2010, which can be compared in scale with separate graphic editors. But, even if you are not faced with the task of becoming a graphics processing specialist, you need to know the basic concepts. Actually, the main ways to customize images were outlined in this article.

We constantly take pictures - our children, relatives and friends, nature, pets. Sometimes the quality of our photos does not quite suit us, and sometimes it just upsets us. Therefore, the question - how to improve the quality of photography is by no means idle, but very relevant.

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

This plugin transforms a photo.

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

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

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 we find the command - Settings.

And then in the open tab, select this plugin - Image Adjustment Lab.

Here's what we'll see:

In the viewport we have two photos - one - Initial, the other - Working view- it will show the results of our color correction.

Let's analyze in detail 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 a photo.

8. One View Window– Working view. There is no home window in this variant.

9. View in two windows– original photo and working preview.

10. Split View - in one window Source photo and Working view. You can move the image separation 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 Lab 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 some noticeable changes to the photo.

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

3. Reset to the 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 press the button - Create Snapshot. Here are the thumbnails of the image that we are editing and saving.

Click on any thumbnail and the selected image will appear in the Working Preview window.

Why do we need to save different editing options?

To select the most appropriate image option.

Summarize. Often, the quality of a photo can be improved by using Auto settings.

What if you want more?

Now consider the right tab in the Labs window.

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

Just move the slider in the parameters column. And the result will immediately be displayed in the Working View window.

Often, some stylized photographs are required for the composition.

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 we move a little Temperature slider towards orange.

Let's add brightness and contrast to the photo. Let's move the sliders a little to the right side.

And we constantly see and control changes in the photo in the Working View window.

Slightly increase intermediate tones.

Let's keep this option.

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

On Axis - Hue- first move the slider to the left to pink.

We get a photo in pale purple tones. Save this option - button - Create snapshot.

And in this case, the runner Hue we have gone far to the right. We will also keep this style of photography.

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

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

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

A little add this version of the photo brightness, contrast.
temperature and saturation subtract a little.

Now we can select photo option which suits us the most. Open the thumbnails and look in the Working Preview window.

When we press the button - OK, then we will save the image that is in the Working View window.

After this practical lesson, you will feel free to choose the right brightness and tone for your photo.
