By means of tool Burn (Shading) we strengthen shades on other section of a fragment — the person of the old woman.

1. Activate tool Burn (Shading). It has the same parameters, as the tool of Dodge (Clarification). Install an exposure of equal 20 % and pitch interval Shadows (Shades). Select the suitable size of a paintbrush.

2. Increase a section with the person of the old woman (fig. 9.16,). Make a series of "dabs" in the field of cheeks, an eye, a forehead. Shades became deeper and насыщенней, the person — more indicative (fig. 9.16,).

Tool Sponge (Sponge) is intended for change of a saturation of a section of the image. On the action it is similar to engine Saturation (Saturation) of dialog box Hue/Saturation (Tone/saturation). We reduce saturation of unnaturally bright persons of the old woman and the man.

1. Activate tool Sponge (Sponge) from a palette of tools. In its property bar the list of the paintbrushes, the uncovered list of modes (with two variants are allocated: Saturate (to Increase a saturation) or Desaturate (to Reduce a saturation)), and also data entry field Pressure (Pressure) where the effect level is set.

2. Install mode Desaturate (to Reduce a saturation), set an exposure of 30 % and select a paintbrush in the size 45—65 пикселов. Lead the tool under images of persons, removing superfluous color from lips and a nose of the old woman, a forehead and leaked men. Save the document.

3. Now change a tool mode on Saturate (to Increase a saturation), and an exposure increase to 50 %. Select the big paintbrush with soft edges and lead on the red coquette on a T-shirt of the girl. On a photo there was an attractive red stain. Save the document.

4. Compare the document after editing to the source file. Isn't that so, the retouch made a photo of more indicative?

Color is very strong graphic means. It is masterful the fitted combinations of color on the image can transform it from an ordinary photo into a work of art. However who told, what it should be those colors which we see in a reality? On the other hand, and absence of color too can turn to effective reception (pictures ink and coal, black-and-white photooperations and пр). The set of the magnificent techniques using color and its absence as special indicative means Is known. More low we consider some special effects which apply half-tone representation. In this section receptions of toning and color usage "not to destination", and as special art means also will be described.

Dialog box Channel Mixer (Mixing of channels) gives access immediately to color channels and allows to modify them by mixing. Thus you control brightness both initial, and resultant channels. Mixing is applied to color correction, toning and creation of color effects. Here we only get acquainted with principles of operation of the given dialog box.

1. Open a file Things.jpg.

2. Select command Channel Mixer (Mixing of channels) submenu Adjust (Correction) of menu Image (Image). On the screen — the dialog box with the same name (fig. 9.17). All changes in channels are reflected in a document window and in palette Channels (Channels), therefore allocate a dialog box so that both the palette and a document window were well visible. Install flag Preview (Review).

3. From uncovered list Output Channel (output Channels) select the output channel in which you will mix initial channels. Now in the list channel Red (Red) is set as the day off.

4. Initial channels are presented by scales with slider. At present the slider on scale Red (Red) is on 100 %, i.e. the red initial channel has 100 %-s' representation in the red output channel. The content of remaining initial channels (dark blue and green) red is equal in the day off 0.

5. Select from list Output Channel (output Channels) by turns all three points. You are convinced that appropriate initial channels have 100 %-s' representation in the channels of an output. Install again the red output channel.

6. Move slider Red (Red) to the right. The percent of red color in the image raises. Look at a palette of channels. Channel Red image (Red) becomes more light.

7. If to move a slider to the left red color on the image becomes less, and the channel miniature on palette Channels (Channels) is blacked out. Finish slider Red (Red) to value of 0 %. Red color on the image is not present now. To move a slider it is useless further, as value of brightness is already equal to zero. Return a slider of the red channel on a mark of 100 %.

8. Now click on a slider of green color. Move it to the right to a mark of 20 %. Representation of the green channel in the day off red increases by 20 %. The image becomes more red.

9. Reduce percent of representation of the green channel to 0 and more low. Now this initial channel before its adding in the output turns to a negative. The percent of brightness of red color in the image decreases.

11. Select from list Output Channel (output Channels) point Green (Green). We will change Now representation of initial channels in the green output channel. Reduce percent of the green initial channel to About, and red — increase to 100 %. Colors of details of the image strongly changed, isn't that so?!

Those who think that for obtaining of the good halftone image from color it is enough to click at line Grayscale (Gradation gray) in list Mode (Mode) of menu Image (Image), have a little simplified sight at things. Far not each image which perfectly well looks in color execution, it is possible to translate thus with success in the half-tone. Here it is necessary to remind the reader that exists two types of contrast: on brightness and on color. Halftone images have contrast only on brightness, and color — both brightness, and color (but in each separate case one prevails any). On applied to a diskette there are the color images perfectly illustrating these two types of contrast.

Example of the image with high contrast on brightness is the file Acropol.jpg. In it boundaries of subjects are selected in the core at the expense of a difference in brightness пиксело

1. Open this image.

2. Translate it in model Lab.

3. Look at color channels (fig. 9.18,). If in the channel of brightness you see accurately worked image, in color channels — only vague shades without visible details.

4. Translate the image in the half-tone. It remains indicative: the acropolis all as is brightly selected against the dark southern sky.

Example of the image with contrast, in the core, on color is, strangely enough, Pyramid.jpg.

1. Open the document. Contrast in it high, and a pyramid looks very expressively.

2. Translate the document in model Lab and look at channels. Strangely enough, all three channels have the considerable number of details, and the channel b — also rather quite good contrast (fig. 9.19). At the same time contrast in the brightness channel is a little lowered.

3. Transform the image to the half-tone. It saved sharpness, but absolutely lost expressiveness. Now not at once you will disassemble, where the pyramid comes to an end and the sky begins. All became identical dark gray color.

4. Save a state picture, and then cancel image transfer in half-tone as the method applied by us here does not approach. The image with contrast on color needs to be translated in half-tone more refined methods.

For conversion of the given image we use the special tool, allowing to produce arithmetical actions with image channels.

Mixing of channels with success is used for creation of the general half-tone channel by mixing of the initial. To begin with it is necessary to clarify, at what of channels there is the greatest contrast and what contains most of all details. At addition of these two channels in a certain proportion the optimal variant of the halftone image also turns out. If there is a channel in which brightness is allocated in a reverse ratio, i.e. the brightest areas of the color image belong to the most dark sections such channel too benefits — it is possible to superimpose its negative (i.e. to subtract the channel). Then total contrast on brightness still increases.

1. Return to an initial state of the document Pyramid.jpg.

2. Open palette Channels (Channels) and look at contents of each of color channels. As one would expect, the greatest contrast on brightness is present at channel Red (Red) (as a pyramid yellow) and in channel Blue (Dark blue) (as the sky dark blue). But in the red channel unduly light sky, and in dark blue — opposite, unduly dark. In the green channel most of all details, and in it the sky and a pyramid have about identical color.

4. Open window Channel Mixer (Mixing of channels). For halftone image obtaining it is necessary to install flag Monochrome (Monochrome).

5. Above there is a list of output channels. In our case (at installed flag Monochrome (Monochrome)) it has only one value — Black (Black) as the created halftone image contains the unique channel.

6. Engines of channels are more low allocated. At present the slider on scale Red (Red) is installed in position of 100 %, i.e. the red initial channel has 100 %-s' representation in the output channel. The content of remaining initial channels (dark blue and green) in the output channel to equally zero. Include flag Preview (Review).

7. Regulating engines of green, red and dark blue channels, achieve the best type of the image. For saving of initial brightness of the document the total sum of values on input channels should be 100 %. The most suitable the parameters presented on fig. 9.20 seemed to authors.

8. For control of the general brightness use an engine
Constant (Transparency). Its offset in a positive side increases brightness, in negative — reduces. Reduce brightness, and see, how the image darkened.

9. When you achieve the optimal total, push the button APPRX. If you saved a picture of the halftone image created by command Grayscale (Half-tone), it is possible to compare results. The difference impresses, whether not so?

Toning — rather popular reception both in polygraphy, and in a photo. More precisely, in a photo process of coloration of a black-and-white print is called toning and is produced by means of the special chemical compound carrying a title "bend". Different compositions of bends create various color hues: сепия (brown), red, green

To toning in Photoshop apply the duplex press (it is considered more low) and a toning mode in window Hue/Saturation (Tone/nasytsennost).

6. Open the document Mill.jpg. Select from quality of the core dark blue color

7. Execute command Hue/Saturation (Tone/saturation) I will change Adjust (Correction) of menu Image (Image). In appeared дшшоговомок do not install flag Colorize (Toning) (fig. 9.21).

3. Changing position of engines Hue (Tone), Saturation (Saturation) and Lightness (Brightness), you receive any shade of toning. In our case sine-steel tone is very interesting looks, but, maybe, it is necessary to you to liking brown more. Push button OK and admire result.

For giving by the shade image use also duplexes. The Duplex - is a method of the press of the monochromatic pitch image several colors from which the main is black, and remaining colors - плашечные, and, as a rule, light. The given method of the press apply нетолько to giving of the necessary shade, but also for improving of quality of halftone images. Complementary colors, being superimposed on gray tone strengthen density and expand an acoustical range. Considering well printed duplex, you even can and not guess that that color color has been used.

As a duplex print плашечными colors under the special circuit of the image of this type select in separate type, instead of carry neither to color and nor to the half-tone. We work with a duplex:

6. Open the initial document Mill.jpg (without correction). Translate it in a half-tone mode.

At once to transform to a duplex the color image the program does not allow.

8. Select command Duotone (Duplex) from list Mode (Mode) of menu Image (Image). Before you dialog box Duotone Options (duplex Parameters) (fig. 9.22). In uncovered list Type (Type) is set number of colors by which the image will be printed: Monotone (One color), Duotone (Duplex), Tritone (Three colors) and Quadrotone (Four colors). Install the press in two colors.

3. Lines of colors are more low allocated. As type Duotone (Duplex) is selected, in a window (the first of them — two lines are accessible to black color). We define the second color. Click on the sample of color in the second line (at present it white). Dialog box Custom Colors (Color swatch) (fig. 2.45 see) opens. Install suitable color, for example the blue. The image is mandatory darkens, but it is easy for correcting then.

4. Push the button APPRX. Colour of the sample became blue, and in the field of a name there was a standard title.

5. Now it is necessary to set allocation of colors. For this purpose use the circuit to the left of the sample. Click on the circuit of allocation of black color. In appeared window Duotone Curve (a duplex Curve) the graded curve shows on a y axis of value of density of color, and on axis Х — gradation gray: from white at the left to black on the right.

6. By default allocation linear, i.e. corresponds to 20 %-s' gray filling density of color of 20 %, 40 %-s' — density of 40 % and etc. Given dependence can be expressed a straight line, setting only two points — initial (0 %) and finite (100 %). Therefore the allocation schedule — a direct diagonal.

7. In data entry fields gray levels through each 10 % and density of color corresponding to them are marked.

8. Click the mouse at center of a straight line and tow a point downwards. Thus you reduce percent of density of color of the gray. Lower a curve until in the field of input 50 there will be no value 20 is means that 50 %-s' level is transferred by 20 %-s' density of printing color. Remaining levels are modified accordingly.

9. If it is necessary, change also allocation of blue tone. Upon termination of editing push the button APPRX. the Duplex it is constructed.

Set Photoshop includes some tens dial-ups of duplexes. They are stored to \Presets\Duotones address of a principal folder of the program. In three directories are collected two, three and four-colourful duplexes. For loading of any of them open window Duotone Options (duplex Parameters) and push button Load (Loading). You also can save own setting of a duplex and even graded curves separately.
