How to increase the brightness of a photo in paint. Editing photos using standard Microsoft tools - let's make the photo lighter in a couple of clicks. An easy way to change the background
Posted 02/14/2012 09:34 AM Paint Shop Pro X4 provides ways to adjust the brightness as well as the contrast in your images, which creates differences between the light and dark pixels in the image. By applying commands to a selection or an entire image, you can do the following:
manually determine brightness and contrast;
setting individual brightness in the image;
defining highlights (75% hue), midtones (50% hue) and shadows (25% hue) to ensure smooth transitions between them;
distribute pixel brightness values more evenly from black to white;
increasing overall contrast when the histogram does not cover the entire brightness spectrum;
determine settings for brightness, contrast and gamma in the image;
creating a pure black and white image.
7.3.1. Adjusting the light, mid, and dark tones of an imageTo adjust light, midtones, shadows and organize a smooth transition between them in the selected area, the command Adjust → Brightness and Contrast → Highlight/Midtone/Shadow is provided. After executing this command, the Highlight / Midtone / Shadow dialog box opens (Fig. 245).
If nothing is selected in the image, then adjustments are made for the entire image.

The Shadow, Midtone, and Highlight parameters determine the values for the shadows, midtones, and highlights in the selected area, and, if nothing is selected in the image, for the entire image. The numeric 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 have the following positions:
Absolute adjustment method - Sets 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 individual photos. Increasing values lighten the area, and decreasing values darken it.
Relative adjustment method - adjusts brightness levels relative to their initial states. Positive values lighten the area, while negative values darken it.
7.3.2. Installation histogramThe tone histogram allows you to analyze the tonal range of an image and redistribute the balance of shadows, midtones and highlights.
To adjust the tones in an image or selection, you need to run the command Adjust → Brightness and Contrast → Histogram Adjustment. After executing this command, the Histogram Adjustment dialog box opens (Fig. 246).

The Edit switch determines the type of histogram being edited:
Luminance - allows you to edit the histogram based on the brightness of the image;
Color - Allows you to edit the histogram based on one of the color channels of the image. After selecting this switch position, the list to the right of this position becomes available, in which you need to select the color channel on the basis of which the active image will be edited.
The Presets list offers ready-made adjustment options. When you select any of them, the Edit switch is automatically reset to the Luminance position. The Default preset value does not represent any additional installations in the image.
In the parameters located below the graph, you can change the values using both absolute values and relative (percentage) values.
The Low slider starts on the left side of the histogram, positioned between the left edge of the graph and the point where the curve begins to rise. This gap shows that the dark pixels in the image are not completely black. This parameter displays the percentage of pixels that are between zero and a low value - their contrast will be lost. As a general rule, set the low level value to less than 0.1%. This parameter can also be adjusted using the dark gray slider.
The High slider starts at the right side of the histogram, positioned between the right edge of the graph and the point where the graph reduces to zero pixels. This option changes the light pixels in the image to white. As general rules, set this parameter to less than 0.1%. This parameter can also be adjusted using the white slider.
Gamma slider - If the overall image is too dark or too light, then you need to adjust the gamma, which is a standard measure of the change in contrast in images. If the image is too dark, move the Gamma slider (gray triangle) to the right to increase the gamma. If the image is too light, move the Gamma slider to the left to decrease the gamma setting.
Midtones slider (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 need to be compressed. Shadows and highlights need to be expanded to show the information they contain. This often happens when taking flash photography when the subject is too close to the camera; the subject appears brightly lit, but the background of the photograph is created dark. To compress the midtones, move the Midtones slider vertically. If the graph peaks in the center and has low pixel counts on the left and right sides, then expand the midtones by moving the Midtones slider down.
If you are creating artistic effects, you can use the Output Max () and Output Min () controls to the left of the histogram. The Max engine is a white circle on a gray background, and the Min engine is a black circle on a gray background. In order to darken the light pixels in the image, you need to move the Max slider down. In order to lighten dark pixels in the image, you need to move the Min slider up.
Even if the sliders move along the vertical axis, Max parameters and Min (ranging from 0 to 255) affect the horizontal axis. All pixels outside the range are transformed so that they are within the range.
If you just want to improve your image, then you don't need to use this option.
The triangular buttons below the Gamma slider determine the scale of the histogram and nothing else. Left button increases the scale, and the right button decreases the scale of the histogram. The 1:1 button sets the histogram scale to 100%.
Color selectionThe active brush color (primary color) is changed by clicking the left mouse button, the active background color is changed by clicking the right mouse button.
Lines, curves, and contours of shapes are drawn with the color of the brush, and fill, spray, brush, and pencil also work in this color. The cavities of the figures are colored with the background color. The eraser, when erasing the drawing, leaves behind the background color.
Color change
The color panel holds 28 colors. 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 (from 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 “manual” selection, a color can be determined by its code – “Hue, Contrast, Brightness” or “Red, Green, Blue”.
After setting a 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 “drawings\hare.bmp” (Edit – Insert 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 as the background color, black as the brush color and, using the colored eraser (i.e. 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 “drawings\bird.bmp”
7. Color it as desired 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 connected external plugins for Paint.NET. The figure below shows a minimal view of the Adjustments menu as it looks in a newly installed Paint.NET editor.
To illustrate the effect of each command from the "Adjustments" menu item, we will use the image below. This is the original image. The description of most of the commands on this page will give an example - a drawing obtained from the original one by using one or another Paint.NET command from the "Correction" menu.
Auto-leveling color levels in Paint.NET Menu item "Auto leveling" in the "Correction" menu graphic editor Paint.NET is designed to equalize the color of an image. Too dark or, conversely, too bright areas 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 image below. This command is equivalent to the "Levels" correction with the default parameters and the "Auto Level" button pressed.
Adjusting the Brightness and Contrast of an Image in Paint.NET The menu item "Brightness and Contrast" is intended to make the colors in the picture darker or lighter, or to make them more contrasting. The dialog box for this function has two parameters: "brightness" and "contrast", respectively.
This is what the original image will look like if you make it brighter.
This is what the original image will look like if you make it more contrasty.
And this is what the original image will look like if you make it brighter and more contrasty at the same time.
Size an image to fit the window in Paint.NET The "Fit to Window" command scales the image so that it fits completely into the work area. This is convenient for large images so that you can see the entire drawing. However, executing this command does not increase the image scale by more than 100%, which can be seen when using it on a small image.
Adjusting Color Curves in Paint.NETThe "Curves" command is intended for visual control of color in the form of curves. A separate instruction page is devoted to this “Curves” menu item.
How to make an image black and white in Paint.NETThe "Make Black and White" menu option provides an easy way to remove the colors from an image and make it grayscale and black and white. An example of applying this correction to the original image can be seen in the figure below.
Changing the hue and saturation of a drawing in Paint.NET The Hue and Saturation command is used to change the saturation of colors in an image or change their shades. 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 “Brightness and Contrast” command described above, because The results from using this function may vary.
If you apply the Hue and Saturation command to the original image? with the value of the "hue" parameter 88 and the "saturation" parameter 158, then the result will be the same as in the figure below.
How to Make a Photo Negative in Paint.NET The "Invert Colors" command is similar in effect to turning a photograph into a negative. This command replaces the colors with the opposite ones. So, if you apply this command to an image twice, you will get the original image again. If we apply this command to the source image from our example, the result will be the same as 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. The "Levels" command has a separate page dedicated to it.
Coarsening image colors in Paint.NETThe Roughen command allows you to reduce the number of available colors used in an image. Typically, there are 256 possible values (from 0 to 255) for each color channel: red, green and blue. Using the Coarse 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 Create a Sepia Effect in Paint.NET The Sepia command first turns 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 cuttlefish. This paint was used by artists in the mid-eighteenth century when painting pictures. Natural sepia was used to tint photographs brown. The effect of sepia in photography is the transformation of silver into sulfide, which becomes more resistant to fading. That's why 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.
