Photoshop tools and plotting

I. Photoshop plotting tools

Photoshop has many drawing tools, including paint brushes, pencils, history paint brushes, art history paint brushes, photo and leather stamps, pattern stamps, Erasers, background erasers, Magic Erasers, blur, sharpen, smear, deepen, fade, and tools such as sponge.

Ii. Set the paint brush

When using paint brushes, history paint brushes, and other drawing tools, you must select an appropriate size paint brush in the toolbar to draw the drawing.

1. Paint Brush Function

Select a drawing tool. For example, if you select the paint brush tool, the toolbar changes to the parameter settings of the paint tool. There is a brush drop-down list box, click the lower triangle button on the right to open a drop-down panel, from which you can select different sizes of paint.

There are three different types of brushes in the brush drop-down panel.

The first type of paint brush is called a hard edge paint. The lines drawn by this type of paint brush do not have soft edges. The second type of paint brush is a soft edge paint which is called a soft edge paint for ease of description; the third type of paint brush is irregular.

Note: When drawing with a pencil tool, you cannot use a paint brush with soft edges, because the pencil is always hard edges.

2. Create and customize a paint brush

To meet the drawing requirements, you can create a new paint brush for drawing. Method: (1) Click the window/brushes command or click the button on the right of the toolbar (
You can open the brushes panel, click the triangle button in the upper right corner of the brushes panel to open the brushes panel menu, and execute the new
Brushes (new paint brush) command; or place the mouse pointer over a shape paint brush and right-click it. In the shortcut menu that appears, select new
Brushes command, which can be set.

Note: when defining a special paint brush, you can only define the shape of the paint brush, but not the color of the paint brush. Therefore, even if you create a paint brush with a beautiful color image, the drawn image does not have any color effect, because the color is determined by the foreground color when drawing with a paint brush.

3. Change the paint brush settings.

Whether it is a new paint brush or an existing paint brush, its diameter, spacing, and hardness do not necessarily meet the needs of the user's painting, so you need to set the existing paint brush.

4. Save, install, delete, and reset the paint brush.

After creating a new paint brush for future use, you can save the settings of the entire brushes panel by clicking the Save brushes (storage paint brush) command in the brushes panel menu. Save the file in the format of *. ABR.

Note: you cannot select the brushes presets option in the brushes panel before running the Save brushes command in the brushes panel menu.

You can install and use the saved paint brush by running the load brushes (load paint brush) command in the brushes panel menu.

Note: When you select the brushes tip shape option in the brushes panel, you cannot delete the paint brush.

(1) Replace Brushes: click this command to replace the original paint brush on the brushes Panel while installing the new paint brush.

(2) reset brushed: Used to reset the paint brush in the brushes panel.

(3) Rename brush: select this command to rename the selected paint brush.

(4) text only (show text only): select this command to display only the paint brush name on the brushes panel.

(5) Small Thumbnail (small thumbnail): select this command to display a small icon in the brushes panel. The BASIC icon shape is the paint brush shape.

(6) Large Thumbnail (large thumbnail): select this command, that is, not only the big icon is displayed in the brushes panel.

3. drawing tool option settings

Each tool has an option parameter. Therefore, different options are displayed in the toolbar when different tools are selected.

1. mixed color mode

The control of the color mixing mode is a prominent function of Photoshop. You can achieve some unexpected results by mixing different colors to complete some difficult operations.

Color Mixing refers to mixing the color applied by the current painting or editing tool with the original background color of the image to produce a result color.

The features and functions of various mixed modes are as follows: select the paint brush tool and open the mode drop-down list in its toolbar. The tool provides 24 color mixed modes:

(1) normal (normal): This is the default mode in Photoshop. After this mode is selected, the color will cover the original background color, when the color is translucent, the color at the bottom is revealed.

(2) dissolve: The result color will randomly replace pixels with background or mixed colors, depending on the opacity of the pixel position.

(3) clear: Like behind, it is only valid for transparent background layers.

(4) behind (behind): This option can be used only for transparent background layers. This option can be used only when the layers (), (), and () buttons are not selected on the layers panel.

(5) Multiply: When this method is selected, you can view the color information in each channel and multiply the background color with the mixed color. The result color is always darker.

(6) screen: This mode is opposite to the multiply mode. It is used to multiply the complementary color of the drawn color and the background color, so the result color is always lighter than the original color.

(7) overlay: Implements multiply or screen mode based on the background color and shade of the image, and keeps the background color unchanged.

(8) soft light: dimmed or brightened by a mixture of colors.

(9) Hard Light: implements the stacked or screen mode of the front slice for the color, depending on the mixed color.

(10) vivid light: increase or decrease the color by increasing or decreasing the Contrast Based on the brightness and shade of the mixed color.

(11) Linear Light: increase or decrease the brightness of a mixed color by increasing or decreasing the brightness.

(12) PIN Light: The color is replaced by the brightness of the mixed color.

(13) color DODGE: view the color information in each channel to brighten the background color to reflect the drawn color.

(14) color burn: reduces the pixel color brightness to display the drawn color.

(15) darken (darken): The brightness between the drawn color and the background color is compared during blending. The brighter pixel is replaced by the darker pixel, while the darker pixel remains unchanged.

(16) lighten: In contrast to the darken mode, select the background color or the highlighted pixel in the painting color as the result color. The darker pixel is replaced by the brighter pixel, the brighter pixels remain unchanged.

(17) difference (difference value): the brightness of the drawn color and the background color is reduced, and the color with a higher brightness is subtracted from the color with a lower brightness.

(18) Exclusion (Exclusion): creates an effect similar to the difference mode but with a low contrast.

(19) hue: Creates the result color by using the brightness and saturation of the base color and the color to draw the color.

(20) saturation (saturation): After mixing, the color and brightness are the same as the base color, and the saturation is the same as the drawn color.

(21) color: Use the brightness of the base color and the color and saturation of the mixed color to create the result color.

(22) luminosity (photometric): Creates the color of the result using the background color, the saturation, and the brightness of the mixed color.

Iv. Photoshop plotting

1. Paint restoration Tool

The restoration paint brush tool is a new tool added by photoshop7.0. It can be used to copy all or part of a pattern to the same or another image consecutively, the image is complementary to the original base of the copied image.

Note: When you use the restoration paint brush tool for copying, a cross-line mark will appear on the Sampled Image to produce the original image that is currently being sampled.

2. Repair tools

The function of the repair tool is similar to that of the repair Brush tool. The repair tool also contains heal selection and use.
Specifies the pattern button. The heal selection button can be used to remove and blur the image within the selected range to make the joint stitching better. Use
The pattern button can fill the pattern content in the selection range.

3. Paint Brush tools

The paint brush tool can draw a gentle line, and its effect is like a line drawn with a brush. You can set opacity, color blending mode, and concentration options in the toolbar of the paint brush tool.

4. Pencil tools

Pencil tools are often used to draw lines highlighted by edges, just as they are normally drawn using a pencil. The Pencil tool can set options for opacity and color blending modes. In addition to these options
Auto
Erase (Auto erase) check box. The role is: when it is selected, the Pencil tool implements the erasure function, that is, when drawing in an image area with the same color as the foreground color, it will automatically erase the foreground color and
Enter the background color.

5. Stamp tools

There are two types of stamps: rubber stamps and pattern stamps. The rubber stamp tool can copy all or part of an image to the same image or another image. The pattern stamp tool can be used to copy the defined pattern content to the same image or another image.

Note: You can use a paint brush of different sizes when using the stamp tool. In addition, when the content of an image is copied to another image, the color pattern of the two images must be the same.

6. Eraser tools

The eraser tool is used to erase the image color and fill in the background color on the erased position. If the erased content is a transparent layer, the erased content becomes transparent.

When using the eraser tool, you can set opacity, fade, and wet edges in the brushes panel. In addition, you can select a pencil or block to erase the image from the mode drop-down list.

7. Background eraser Tool

The background eraser tool is the same as the eraser tool to erase the color in the image, but the two are different. That is, the background eraser tool does not fill in the background color after the color is erased, but changes the erased content to transparent. If the erased layer is a background layer, the background layer is automatically changed to an opaque layer after the background eraser is used.

8. Magic eraser Tool

The magic eraser tool has the same functions as the eraser tool and can be used to erase colors in images. However, this tool has its own unique features, that is, it can be used to erase adjacent colors within a certain degree of tolerance, after the color is erased, the color will not be replaced by the background color, and then become a transparent layer.

In the toolbar of the magic eraser tool, you can set tolerance, anti-aliased, contiguous, and use all layers for all layers) and opacity (opacity) options.

9. gradient tool

You can use a gradient tool to create a gradual mixing of multiple colors. In essence, you can fill in a blending color with a multi-color transition in the image or a certain area of the image.

The parameters of the gradient tool are as follows:

(1) gradients drop-down list box: this drop-down list shows the gradient color preview effect, and click the small triangle button on the right to open the gradients panel.

(2) reverse (reverse): After this check box is selected, the filled gradient color is the opposite to the gradient color set by the user.

(3) gradient tool: There are five tool buttons in the toolbar: linear gradient (linear gradient), radial gradient ),
Angular gradient (angle gradient), reflected gradient (symmetric gradient) and diamond
Gradient (diamond gradient ).

(4) mode: select the gradient color mixing mode.

(5) opacity (opacity): You can set the opacity of the gradient.

(6) dither (imitation color): select this check box to show the intermediate color, so that the gradient effect is smoother.

(7) Transparency: select this check box to enable the transparent mask function, so that transparent settings can be applied during gradient filling.

10. paint bucket tools

The paint bucket tool can fill the image with colors, but it only fills areas of the image with similar colors. To make the paint bucket tool more accurate when filling the color, you can set parameters in its toolbar. These parameters
Number of options: color mixing mode, opacity, anti-aliased, tolerance, and neighboring pixels
Contiguous and fill.

11. Blur, sharpen, and smear tools

You can use the Blur tool and sharpen tool to produce clear and fuzzy image effects. The Blur tool is used to reduce the contrast between adjacent pixels of an image, soften the border or area of the image, and produce a blur effect. The sharpening tool is the opposite of the fuzzy tool, which increases the contrast between adjacent pixels of the image, so that the image looks clear and clear.

Note: When you use the fuzzy tool, if you press the Alt key, the tool becomes a sharpening tool, and vice versa.

The smear tool simulates the effect of hand-stirred painting. Use the smear tool to extract the color of the selected click and combine it with the color of the place where the mouse is dragged.

Note: The Blur, sharpen, and smear tools cannot be used for bitmap and indexed color pattern images.

12. Deepening, fading, and Sponge tools

The deepening tool and fade-down tool are tone-based tools that can change the exposure of a specific area of an image to make the image dimmed or brightened. Use a sponge tool to increase or decrease the saturation of the image area very accurately.

5. process text

1. Basic Input text operations

Photoshop7.0 has more powerful text processing functions than photoshop6.0. Users can control more texts. For example, they can perform multi-Text Formatting on the same text layer, it can automatically wrap the text when you enter the text, and use the text conversion path.

2. Input paragraph text

Photoshop7.0 provides three types of text input methods: one is the most basic mode, the other is text input in the form of paragraphs, and the other is text input in the form of masks. Method: Click the text tool, move the mouse pointer to the image window, press the mouse key, drag a rectangle, and enter the text in the rectangle.

You can enter a long paragraph of text within a specified range, and the text will be automatically wrapped during the input process. When a row does not fit, the text will automatically jump to the next line; if the entered content is in English and a word cannot be placed at the end of a row, the row is automatically disconnected, that is, a hyphen is automatically added to the English word.

3. Input text Selection Range

Another method of photoshop7.0 is to use the text mask tool to input text, which can generate a Text Selection Range to make some special text. Method: select the text tool in the toolbox, select the text mask tool in the toolbar, and click and enter text in the image window.

Note: A layer is not automatically generated in the layers panel when text is input using the text mask tool.

4. edit text format

The text layer has the flexibility to be modified repeatedly. Therefore, when the input text content is incorrect or the user is not satisfied with the text format, the text content can be modified and edited again. Method: first in the toolbox
Select the text tool, move the mouse pointer to the text layer preview thumbnail in the layers panel, double-click, or click an existing text position in the image window, and then click window
/Character command.

5. Text Search and replacement

Find and relace (search and replacement) is also a new feature of photoshop7.0. It is as convenient and easy to use as word search and replacement. Select the Edit/find and replace text command.
