The commands in this menu are designed to correct the color of an image in various ways.
The following image will be used to illustrate the various adjustments available in this menu:
Auto leveling
This command is used to automatically adjust the color of an image. As a result of its application, images that are too dark or too light are brought back to normal levels. The result is equivalent to pressing the “Auto Level” button in the “ ” command dialog of this menu.
After using this command, which has no configuration options, our image will look like this:
After applying "Auto leveling"
Invert colors
The effect of this command is very similar to taking a negative of a photograph. Applying it again will return the original image.
Our image after color inversion:
After applying “Invert Colors”
Coarsening...
This adjustment allows you to reduce the number of acceptable color values in an image. Usually everyone color channel has 256 possible values (from 0 to 255), but with this command you can limit this range from 2 to 64. This allows you to "posterize" the image, give it a "retro" style or a "false anti-aliasing" look.

After using "Coarsening..."
Hue and saturation...
This operation can be used to change the hue and color saturation of an image. Additionally, in the command settings window you can adjust the “lightness”, which is similar, but not the same, as brightness.
This is what our image will look like after applying this command, with the Hue value set to 88 and Saturation value set to 158:
After applying “Hue and Saturation...”
Make it black and white
This adjustment removes all color, making the layer black and white.

This operation is used to adjust the color range and gamma of the image. Additional information look at
Unfortunately, amateur photographs are not always pleasing to the eye, but you really want to capture unforgettable moments of life in them. However, often such photographs turn out either too dark, or, on the contrary, too light. Or the colors on them turn out to be completely unnatural (this happens especially often when using cheap color film): trees turn poisonous green, gray asphalt for some reason takes on an intense blue color, the sky turns from blue to a greenish tint, slightly tanned skin turns red, as if the shooting took place in a sauna, and not in a cozy cafe, etc. It’s no less disappointing when an interesting shot turns out to be blurry and blurry and doesn’t make the right impression, or the most beautiful architectural structures in the photo acquire a lot of geometric and optical distortions, or due to a bad angle When shooting, most of the photograph is occupied by unimportant details, and the main subject is somewhere to the side. In addition, many cameras produce red-eye when using flash, and when scanned, images often become darker and blurry. A special discussion these are old or not quite old, but already faded photographs that I would also like to “revive”. In addition, there may be dust and scratches, emulsion peeling, development and printing defects, etc. The reasons for all this include a lack of professionalism, bad shooting time and inappropriate weather conditions, as well as the use of cheap and low-quality cameras and appropriate film.
As a result, in most cases, photographs have to be edited, so photo correction functions are provided in almost all modern graphics packages. Our today's lesson will be devoted to the Paint Shop Pro package, tools automatic correction which can significantly improve pictures even for non-professionals. However, the arsenal of capabilities of this package also includes tools designed for professional photographers and designers, which allow them to achieve phenomenal results. And within the framework of this article, we will focus on correction tools that are available to the general public and do not require any additional professional knowledge.
To correct photographs in Paint Shop Pro, the Photo toolbar is used, opened by the command View=>Toolbars=>Photo (View=>Toolbars=>Photo), all the main photo enhancement options designed for amateurs are collected here. In addition, the command menu has an Adjust command, which gives access to both commands from the Photo panel and a whole range of more complex, but no less useful, correction methods. Equally useful are the Straighten and Perspective Correction tools from the Tools toolbar.
Each of the customizable correction options has a preview mode; as a result, all changes made immediately become visible on the corrected image or on the selected area. In addition, in many dialog boxes You can use the Save Preset button to save adjustment settings so that they can be applied to other images later.
Geometric distortion can be divided into perspective and optical, created by the lens due to its imperfection.
All lenses introduce optical distortion, or distortion, to one degree or another. Distortion manifests itself in the fact that the scale of the image in the center and at the edges is not the same. Professional photographers, keeping this in mind, resort to various tricks, but in the end they also have to eliminate optical defects from photographs, since they cannot be completely prevented during shooting.
As for perspective defects, the most easily corrected defect of this kind is the tilt of the camera during shooting, which manifests itself in the fact that the objects in the photograph turn out to be located at a certain angle. This is a problem for many inexperienced hobbyists, and Paint Shop Pro solves it extremely simply thanks to the presence of a special tool.
Correcting perspective distortions in large panoramic photographs and photographs of architectural structures requires much more effort. The fact is that in the absence of special equipment, in order to photograph the entire building, you will have to use the widest possible lens and tilt the camera upward (otherwise half the frame will be taken up by the asphalt) as a result, there will be a sharp convergence of vertical lines in the photographs. To eliminate this phenomenon, perspective correction is necessary.
Correcting distortionThere are two main variants of distortion: Barrel Distortion, in which objects in the image appear swollen (Fig. 1), and Pincushion Distortion, when the extreme verticals and horizontals are concave inwards (Fig. 2).
It should be noted that Paint Shop Pro is the only graphics package where distortion correction is implemented extremely simply (in Adobe Photoshop this is achieved in a much more complex way). Here the Barrel Distortion Correction and Pincushion Distortion Correction commands are intended for this purpose. They can be called up both from the command menu Adjust=>Lens Correction (Adjustment=>Lens Correction) and from the Photo toolbar.
For an example, open Fig. 3 with pronounced barrel distortion, click the Barrel Distortion Correction button and set the Strength to in this example the value taken is 85 (Fig. 4).
If, due to the inexperience of a novice photographer, the objects in the photograph turn out to be located at a certain angle, then it is easy to straighten them using the Straighten tool. In essence, this will be a regular rotation, but unlike it, Straighten provides maximum convenience when straightening the image, since everything is displayed on the screen, happens within a second and guarantees one hundred percent results.
For example, take a suitable image in this case, Fig. 5 with a clear tilt of the photographed objects to the right. On the toolbar, select the Straighten tool; the result will be the appearance of a horizontal segment in the photo, limited by markers (Fig. 6). Move and slightly rotate the segment so that it extends parallel to any part of the image, which should be positioned strictly horizontally (Fig. 7), and click on the Apply button; the image will be rotated to the angle you specified (Fig. 8) . Now all that remains is to take the Crop tool and trim off the extra background parts of the image that appeared as a result of straightening the photo (Fig. 9 and 10).
Rice. 8. The result of straightening a photo with the Straighten tool
We have previously talked about optical distortions that are possible when shooting. Now let’s look at the perspective distortions that occur when photographing architectural structures. Thanks to Paint Shop Pro's advanced correction capabilities, this operation is no longer a difficult task and even a non-professional can handle it. For horizontal and vertical correction, you can use the commands Effects=>Geometric Effects=>Perspective-Horizontal (Effects=>Geometric Effects=>Horizontal Perspective and Effects=>Geometric Effects=>Perspective-Vertical) And in more complex cases, it is worth turning to the Perspective Correction tool, which provides the user with the functions of keystone and other perspective distortions of an image area.
Let's try to correct the image shown in Fig. 11, where there is both a distortion of perspective and a clear tilt of the image. Therefore, first we straighten the image with the Straighten tool (Fig. 12 and 13).
Now let's move on to the forward correction. First, we will carry out vertical correction with approximately the same parameters as in Fig. 14, since in some cases this is enough to correct perspective. The obtained result is shown in Fig. 15. Next, you just need to crop the photo, but in our case, unfortunately, vertical perspective correction alone will not be enough; you will have to use the Perspective Correction tool and perform a trapezoidal perspective correction. Activate the Perspective Correction tool and limit the perspective contours in accordance with Fig. 16 the result obtained is shown in Fig. 17. Crop the image with the Crop tool (Fig. 18), and then enhance its contrast using the Enhance Photo => command from the Photo toolbar with the parameters shown in Fig. 19. The result of the correction is shown in Fig. 20.
Now let’s look at a more complex example (Fig. 21), where both optical and geometric correction will be required, as well as image straightening. In such situations, the distortion is always corrected first; in this example, you need to use the Barrel Distortion command with the parameters indicated in Fig. 22. Then you should use the Straighten tool to straighten the image (Fig. 23 and 24) and only then proceed to perspective correction with the Perspective Correction tool in accordance with Fig. 25 (Fig. 26) and crop the image (Fig. 27).
As a rule, when shooting with flash, an undesirable effect of light reflection from the retina of animals or humans occurs - the so-called red-eye effect (in practice, this is similar to the eyes of a cat glowing in the dark, only here the eyes glow not green, but red). It is not possible to avoid this situation one hundred percent, although modern camera models make it possible to reduce this effect to a minimum.
Therefore, red-eye removal is available in a variety of graphics packages, and in Paint Shop Pro it is implemented extremely simply and is carried out almost instantly, allowing you to get rid of red eyes in both humans and animals. The Red-Eye Removal command is intended for this purpose. It can be called up both from the Adjust command menu and from the Enhance Photo pop-up list. Please note that the Red-Eye Removal team can also help in cases where it is simply necessary to change the eye color of a person in a photograph.
Let's try to use this opportunity using the example of Fig. 28. After opening the Red-Eye Removal window, you first need to select one of four methods for forming the pupil and iris of the eye: Auto Human Eye, Auto Animal Eye, Freehand Pupil Outline freehand eye contour based on a rectangular area) and Point-to-Point Pupil Outline (Drawing an eye contour by points in the form of a closed polyline). The latter two options can be used to remove red-eye for both humans and animals, but the first two methods are generally more convenient because they remove red-eye faster and have more options. The last two options are intended for non-standard situations, when the shape of the red-colored pupil is very different from round and therefore the first two methods cannot successfully eliminate the red color.
In this case, the situation is simple, so we will focus on the Auto Animal Eye method (Fig. 29). In the Color list, we will determine the appropriate eye color and form a contour around the first eye. To do this, simply draw a rectangular contour in the usual way, adjust its size and position, trying to make the contour match perfectly with the iris of the eye. Then, if necessary, we will adjust other parameters: Pupil lightness, Glint lightness, Glint size, etc. We will carry out a similar procedure with the second eye (Fig. 30). The obtained result is shown in Fig. 31.
Rice. 31. Final image appearance after red-eye removal
Now let’s try to eliminate the red-eye effect using the example of a photograph of a child (Fig. 32). From the Adjust menu, select the Red-Eye Removal command, in the window that opens, set the Auto Human Eye option, in the Hue list, define the eye color, in the Color list ) select the desired shade of the iris. Then, as in the previous case, we will form the required contour around the first eye, trying to eliminate the red-eye effect. Here, if necessary, we will adjust the shade and size of the eye and pupil. We will perform a similar operation in relation to the second eye (Fig. 33) the result obtained is shown in Fig. 34.
Rice. 34. Final image appearance after red-eye removal
As we have already noted, the photographs that come into our hands are not always ideal in color; due to unsuccessful shooting, the colors are often unnatural. When shooting in the dark, certain fragments of a photograph may appear unclear or not be visible at all, an interesting frame will be blurry or not sharp enough, or will have excessively blurred contours of objects. In addition, images are often blurred during scanning, colors in photographs may fade over time, etc. And Paint Shop Pro provides the ability to quickly automatically correct many defects of this kind found in photographs.
Photo correction in one stepThe simplest and quick way image correction use the One Step Photo Fix command from the Enhance Photo pop-up list. As a result, color balance, brightness, contrast and saturation will be automatically and simultaneously adjusted. This option does not give good results for every image, but it never hurts to try.
Let's take Fig. 35, where photo correction in one step helped us significantly improve the appearance of the image (Fig. 36).
Rice. 36. Appearance images after automatic photo correction in one step
Adjusting contrast and saturationSince lack of contrast and saturation in a photo is one of the most common defects, and in Paint Shop Pro both can be corrected automatically in a matter of seconds, this topic requires more detailed consideration.
Pay attention to the photograph shown in Fig. 37, where the contrast is clearly insufficient. To correct the situation, open the Automatic Contrast Enhancement command from the Adjust=>Brightness and Contrast menu, or select the Automatic Contrast Enhancement command from the Enhance Photo pop-up list. with the parameters shown in Fig. 38. As a result, the contrast will clearly increase, and the photograph will take the form shown in Fig. 39.
Rice. 39. Image appearance after automatic contrast adjustment
Now, using a specific example, let’s see what results can be achieved simply by automatically increasing saturation and contrast. The original photograph (Fig. 40) was taken in a cave in clearly insufficient lighting; as a result, many spectacular natural elements are simply indistinguishable. Try using the command (Automatic increase saturation), adjusting the parameters in accordance with Fig. 41. The command can be selected either from the Adjust=>Hue and Saturation command menu or from the Enhance Photo pop-up list. The picture will look like in Fig. 42.
Rice. 42. Image appearance after automatic saturation adjustment
Increasing the contrast with the parameters shown in Fig. will help further improve the appearance of the image. 43. The result obtained is presented in Fig. 44.
Before you start coloring and tone correction image, it is necessary to determine which colors are represented in excess and which are clearly not enough. This is not at all easy for a non-professional to do, so we will focus on the most simple options color correction.
Automatic change color balance this is the easiest and fastest way to eliminate yellow or blue light in the image that appears if the photo was taken at artificial lighting. It is also useful if it is necessary to increase the balance of the named colors, for example, if shooting in the dark is unsuccessful. And sometimes this opportunity It can be useful for photo editing, when you have to adjust the shooting time.
Pay attention to the photograph of Nicole Kidman (Fig. 45), which clearly shows an imbalance yellow color. Let's try to improve the situation a little by at least partially eliminating the yellow flare of the image. Use the Adjust=>Color Balance=>Automatic Color Balance command or select the Automatic Color Balance command from the Enhance Photo pop-up list and adjust it according to Fig. 46. The resulting image will look like in Fig. 47.
Rice. 47. Image appearance after automatic color balance correction
Let's consider the third of these situations and try to change the color balance for the photograph in Fig. 48, where I would like to emphasize the pink tint of the mountains visible in the distance in the rays of the setting sun (in fact, the sun had almost disappeared, and the photo was taken a little later than desired). Select the Automatic Color Balance command from the Enhance Photo pop-up list and configure its parameters as shown in Fig. 49. The result will be rice. 50.
Rice. 50. Image appearance after automatic color balance correction
In more complex cases, you have to resort to correction of all color shades, which is possible using the Color Balance command Adjust=>Color Balance=>Color Balance command. Let's try to use it using the example of Fig. 51, where we would like to restore white to the church gables and reduce the amount of blue throughout the image. Let's open the Color Balance command window and sequentially adjust the color balance for the light areas of the photo Highlights (Fig. 52), midtones Midtones (Fig. 53) and dark areas Shadows (Fig. 54). Be sure to check the Preserve Luminosity checkbox to preserve the photo's luminosity values. The result of the transformations is shown in Fig. 55. To improve the image, it is also a good idea to increase the saturation using the Automatic Saturation Enhancement command from the Enhance Photo pop-up list with the parameters shown in Fig. 56. The resulting image is shown in Fig. 57.
It happens that in the pictures you take, especially when shooting with flash, all or some of the colors look unnatural. And automatic color correction in such cases usually does not give the desired effect. In this case, manual color correction can help out Manual Color Correction, which provides a more powerful alternative to automatic color correction. It makes it easy to improve the quality of even the most complex images while ensuring that any critical colors are accurately reproduced.
Let's take Fig. as a starting point. 58 in this case, the skin tone of the face looks clearly unnatural (too much red), which is most likely due to the fact that flash photography was taken from too close a distance. Let's try to fix it this disadvantage. To do this, carefully select the contours of the face with the Freehand Selection tool, setting it to the Edge Seeker option with the following parameters: Feather 0, Smoothing 0, the Antialias checkbox is on, the Sample Merged checkbox is off (Fig. 59) . Let's take the Dropper tool and remember (or better yet, write down on paper) the parameters of the unnatural dark reddish skin tone as the initial color (Fig. 60).
Then click on the Manual Color Correction button on the Photo toolbar. In the Manual Color Correction window that opens, click on the Source color and enter the parameters of the remembered color. Highlight the Preset Target Color switch, select the Skintones option, open the color block with a list of shades and select the Indian Skin Light option (Fig. 61). Let's turn on the Preserve Saturation checkbox and leave the Preserve Lightness checkbox turned off (Fig. 62). Let's refuse selection with the command Selections=>Select none (Selection=>Nothing is selected). We get the result shown in Fig. 63.
Rice. 62. Final version of the Manual Color Correction settings
Rice. 63. Appearance of the image after finishing manual color correction
Manual color correction is good not only for eliminating photographic defects; it can also be used simply to give one or another image element the desired shade. For example, let's open Fig. 64, featuring a unique white gold ring with pearls from Gruosi. Let's try, using the manual color correction mode, to turn white gold jewelry into yellow. Select the ring (Fig. 65), click on the Manual Color Correction button and adjust the color correction in accordance with Fig. 66 (note that the Preset Target Color list has Metals and Gold selected). The result is shown in Fig. 67.
If you've ever scanned photographs, you've probably had to repeat this procedure more than once because the photo turned out lighter or darker. Another situation is also possible, when due to unfavorable shooting conditions, for example when shooting in the dark, the photographs turn out to be too dark. It is useless to print such photographs, since most of the objects simply will not be visible on them.
In principle, any of these photographs can be corrected and given an acceptable appearance. There are many ways to work with such photos in Paint Shop Pro and it is quite difficult to offer any single solution.
Let's look at the simpler of these methods.
If you need to greatly lighten a photo in order to see hidden details, then the easiest way is to use the Histogram Equalize command. It redistributes the brightness levels of the active layer and can improve an image that lacks contrast or is too dark. Let's try to apply this using the example of Fig. 68. Open the Adjust=>Brightness and Contrast menu and select the Histogram Equalize command. The obtained result is shown in Fig. 69.
Rice. 69. Appearance of the photo after exposure to the Histogram Equalize command
However this method does not always provide the desired result, since the colors in the photo may become unnatural. You can try to go the other way. For example, let's open the original image (Fig. 70) and first perform automatic photo correction in one step by selecting the One Step Photo Fix command from the Enhance Photo pop-up list. As a result, hidden dark fragments of the image will appear, but it will be clear that the overall tone of the photograph is unsuccessful, since there is a clear excess of blue in it; this especially affects the girl’s skin color (Fig. 71). To correct the situation, use the automatic color balance correction mode by selecting the Automatic Color Balance command from the Enhance Photo pop-up list of the panel with the Photo tool and reduce the proportion of blue color, as shown in Fig. 72. As a result, the photo will not be so dark, and the color shades in it will look more natural (Fig. 73).
Rice. 71. Image appearance after automatic photo correction in one step
Now let's see what we can achieve with histogram correction, which allows us to adjust the full range of available color intensities for use in a single image, controlling the balance between shadowed and illuminated parts of the image. The unique benefit of this option is the ability to balance the placement of intermediate tones on the scale between dark and light. For example, let’s open the image shown in Fig. as the source image. 74. Click on the Histogram Adjustment button in the Photo toolbar or call the command Adjust=>Brightness and Contrast=>Histogram Adjustment. Let's configure the histogram parameters in accordance with Fig. 75. The main thing here is not to overdo it, since for most images real improvement in quality is only possible when increasing the gamma correction no higher than 30% at higher values the pictures will look faded. As a result, the photograph will become noticeably lighter and many initially hidden details of the image will appear (Fig. 76).
There is another way - adjusting the levels. Typically, this option is resorted to when the above methods are ineffective and only lead to unnatural lightening of the image, without revealing temporarily hidden darkened details. This situation also occurs in the photograph shown in Fig. 77. In particular, attempts to adjust her histogram do not give the desired effect, and we, for example, absolutely need to highlight the contours of a girl for photomontage. Therefore, we will use the command Adjust=>Brightness and Contrast=>Levels (Adjustment=>Brightness and Contrast=>Levels). Let's set the level parameters approximately in accordance with Fig. 78 the essence of the actions when lightening a photo is that you need to move the gray slider to the left at the Input Levels level. After this, the photograph will also become noticeably lighter and many initially hidden details of the image will also appear on it (Fig. 79).
Approximately the same result can be obtained by simply using the Brightness/Contrast command. Let's take as the original image the same photograph shown in Fig. 77, and use the command Adjust=>Brightness and Contrast=>Brightness/Contrast (Adjustment=>Brightness and Contrast=>Brightness/Contrast), adjusting the parameters in accordance with Fig. 80. The result obtained is presented in Fig. 81.
Over time, photographs age, fade, and become faded. Recovery color range and its optimization in faded photographs, the Fade Correction mode is designed, with the help of which it is easiest to return photos to their lost appearance: it restores, corrects and balances the colors of images, and also automatically adjusts brightness and contrast.
As an example, let’s open a photograph that has already become quite faded (Fig. 82), click on the Fade Correction button on the Photo toolbar and experimentally set the correction value (for example, as in Fig. 83). The colors will be restored, and the image may look like in Fig. 84.
When restoring old photographs, which often have bends, cracks, scratches and other similar defects, things are much more complicated. If these defects are present, it is necessary to painstakingly retouch the photograph using the cloning method, which we learned about in one of the previous lessons. But the techniques we discussed in this lesson can significantly speed up the work and ensure a better result. True, there are no standard techniques here, and for each old photo you will have to select your own ways to restore it.
Quite often, in such situations, photo correction in one step can help at the first stage, allowing you to quickly restore color balance, brightness, contrast and saturation. Let's open Fig. as an example. 85 and use the One Step Photo Fix command from the Enhance Photo pop-up list. The result obtained is impressive (Fig. 86). To some extent, the situation can be improved by adjusting the levels. To do this, use the command Adjust=>Brightness and Contrast=>Levels (Adjustment=>Brightness and Contrast=>Levels) and adjust the level parameters approximately in accordance with Fig. 87 as a result, the picture will be slightly brightened and it will be possible to make out part of the inscription in its lower part (Fig. 88). Now you need to improve the clarity of the image. The most convenient way to do this is with the Clarifi command (Clarification) Adjust=>Brightness and Contrast=>Clarifi (Adjustment=>Brightness and Contrast=>Clarification), which allows you to enhance photos without the appearance of contrasting details that are typical for sharpening effects (Fig. 89 and 90). This command very convenient for restoring both old blurry photographs and photographs taken in poor or diffuse lighting. And then you will have to act manually and remove scratches and traces of dust and dirt.
Rice. 86. Image appearance after automatic photo correction in one step
Now let's look at another situation (Fig. 91) - here we will have to take a slightly different path. First, if possible, we will restore the color balance, brightness, contrast and saturation using the One Step Photo Fix command (Fig. 92). And then, in order to somehow clarify the individual details of the image, we will increase its contrast using the Automatic Contrast Enhancement command from the Enhance Photo pop-up list with the parameters shown in Fig. 93. The result obtained is presented in Fig. 94. If after this you apply One Step Photo Fix again, the clarity of the lines will increase even more and individual fragments of the icon will become more distinct (Fig. 95). The only thing that can still improve the situation and make the picture of the icon more legible is increasing the sharpness of the image. For this purpose, in Paint Shop Pro you can use three commands: Sharpen, Sharpen More and Unsharp Mask from the Adjust=>Sharpness menu. In this case, after applying the command Adjust=>Sharpness=>Sharpen (Adjustment=>Sharpness=>Sharpen), the image took the form shown in Fig. 96.

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 by 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 the color, you can add it to the set additional colors or change 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 down right button mouse), 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”
Questions1) What color will you get if you mix equal amounts of red, green and blue?
2) What color will you get if you mix equal amounts of red and blue?
3) How to get black and white color?
4) What color corresponds to the RGB(0,0,250) code?
Correction
Auto-leveling allows you to bring colors to the average value, that is, very light colors will become darker, dark colors will become lighter.
Invert colors allows you to put an additional color for each color instead of the color that is there. If you have the original drawing as shown below.
Then after completing this mode the next one will appear.
Curves allows you to lighten or darken a drawing according to a schedule. The following window will appear on the screen.
Shown here is a curve (a straight line in the figure) to which the color corresponds, that is, light will correspond to light, dark to dark. Now let's change the shape of the curve. To do this, move the cursor to the line, click on the left mouse button and, without releasing the button, move the cursor to another place. Let's assume that the shape of the curve becomes as shown in the figure below.
Then the original drawing (shown in the previous mode) will become the following.
If you change the curve as shown in the figure below.
The drawing will be as follows.
Moreover, the curve may have an intricate appearance.
And the drawing too. The option for changing the brightness was discussed above, but you can change it according to the RGB scheme.
Moreover, according to this scheme, you can change the primary colors separately from each other.
In order to do this, check the Red box and remove the checkmarks in other colors. Then we move the red curve to the right place. Then we will do the same for green and separately for blue. We get different curves for different colors (and the picture shown below).
Note that the starting point can be moved from bottom to top (for this, when moving, the cursor must be slightly to the left of the graph border). Accordingly, the right point can be set lower.
Coarsening allows you to make the color more or less saturated. Uncheck the Sync option and change the position of the sliders.
As a result, the original drawing
Will be next.
Hue and Saturation allows you to change the hue, saturation, and lightness of a drawing.
Make Black and White removes colors, as shown in the image below.
Sepia allows you to add shades to a black and white image. If you apply this mode to the black and white drawing shown in the picture above, you will get the following picture.
Levels allows you to set color levels. Upon entering this mode A window with histograms will appear on the screen. You can change the level for all primary colors (check the boxes to the left of the color name, where R – red - red, G – green - green, B – blue). But you can set the level for an individual color (by leaving a checkmark next to its name only, and unchecking the others).
