Application and setting techniques of PS brushes

Now we press 〖b〗 to select the Brush tool from the toolbar, and if the pencil is selected 〖shift B〗 switch to the brush. Then press 〖d〗, which is to set the color to the default foreground black and white background. You can also click the default button on the color area of the toolbar (the red arrow at the bottom left). Clicking the blue arrow will swap the foreground and background colors, and the shortcut keys are 〖x〗 if the foreground color is now pressed into white and the back color becomes black.

Then click the red arrow in the Public column to open the brush preset and select the item at the blue arrow. This selects a 9 pixel size brush, the mode is selected normally, opacity and traffic are 100%.

You can also set the main diameter of the brush to 9 pixels without a preset, referring to the following figure. What is the main diameter? Because the brush is a circle, the thickness of the brush is represented by the diameter of the circle. The meaning of hardness will be described later in the content, the hardness is now set to 100%.

If you click the 9 pixel brush option in the blue arrow at the bottom of the green circle, you may have previously changed the brush's preset. At this point click the green arrow at the Round triangle button, in the pop-up menu select "Reset Brush", will appear the following right picture of the query box, click "Good" can be. You can recover from this method later if a brush preset change occurs. Other reset operations such as styles and swatches are the same.

At this point the mouse becomes a circle of the brush size in the image, and if not, first determine that the capitalization key on the keyboard CapsLock is turned off, and then specify a normal brush tip from the paint cursor in the show and cursor item in the Photoshop preferences. The following figure.

Now we use this brush in Photoshop to draw our first pen, press the left mouse button to draw the image, release left end draw. It is no less important than the first footprint left on the lunar surface, so make it look good. The following figure.

Let's take a look at some of the brushes ' options. The brush's options are set in the public column. Now reduce "opacity" to 15%. There are 5 ways to change the opacity of the brush, and these 5 methods are basically applicable to all the places in Photoshop that have similar numerical adjustments.

1: Move the mouse to the opacity value click, enter the number. You can also scroll up and down the mouse wheel (the effect of using the keyboard up and DOWN ARROW keys is the same as the wheel, press shift to accelerate, hold down alt to slow down).

2: Press ENTER directly, at this time the opacity value will automatically be selected, and then enter a number. Note that this method is not applicable anywhere.

3: Click the triangle arrow to the right of the number and drag on the slider that pops up.

4: Move the mouse to the public bar "opacity" text, at this point the mouse cursor will change into a two-way arrow, drag left and right can be changed values, the effect is similar to 3. Hold down the SHIFT key to accelerate, and hold down alt to slow down.

5: Press the number key on the keyboard directly. If changed to 80% Press 8,40% Press 4,100% Press the 0,15% to press the 1 and 5 consecutively. 1% Press 0 and 1 consecutively. This method is the quickest and most practical. But not all places apply.

Reduce brush opacity will reduce the color, strokes overlap will appear to deepen the effect. Note that overlapping brushes must be drawn in order to have a deeper effect, once drawn strokes even if the overlap will not have a deeper effect. This one refers to the left mouse button from press to release, which counts as a drawing. The bottom left figure shows the effect of a one-time drawing and a split drawing, at the top of which is a one-time drawing. You can also use different opacity and different foreground colors to test the effect.

Now we pull up the history palette, the Menu "window history," and you'll see all the steps that have been made since the image was created in the palette. Order from top to bottom represents the from of the operation steps to date. The following is the right figure. Click on the appropriate steps to return to the image after the operation of the state. It's like the time is flowing backwards. This historical record is mainly used to undo the operation, if the image is not satisfied with the modification, you can use this palette to undo.

The steps that can be undone are 20 step by default. If the recorded step is more than 20 steps, the most recent steps will replace the earliest steps. Assuming you have done 21 steps, the "new" step in the first step of the bottom right figure disappears. The historical record of disappearance cannot be recovered. The number of steps in the history record can be modified from the "History status" in the Photoshop preset 〖ctrl K〗 "General". Up to 1000. Be careful not to covet too many historical records, because that will lead to slow running. In most cases, 20 steps are enough.

Even if you do not open the history palette, you can use the shortcut key 〖ctrl ALT Z〗 for gradual undo, one step back. Like "move from now to the past". In the History palette, you'll see that the steps move up in turn. "Back to the past", in the premise of not doing its operation, you can through the shortcut key 〖ctrl SHIFT Z〗 gradually redo, as "from the past step-by-step toward the present."

If you have done something else in the earlier steps, the history that follows is all cleared and the record is restarted. That means "not coming back." Suppose you draw a circle and move a few times, then you go back to the move before you delete the circle, then where does the movement come from? So just as no mother has no children, the historical record is a linear causal relationship.

Now we undo a blank (or another new one) when we create a new one. Change the opacity of the brush to 100%, how to change the fastest? Don't forget the shortcut key that you mentioned earlier, press the number 0 on your keyboard.

Now let's take a look at what the brush's "flow" is for. Bring up the color palette 〖f6〗 or select a more vivid color through the color picker, then change the flow to 1% and smear in the image. At first you will feel that reducing the flow and reducing the opacity effect is almost, gradually will feel different, that is, in a painting, overlapping areas will have a deeper effect. Multiple overlapping colors are more saturated. Just as we draw on the paper with a watercolor pen. The following is the left figure.

Change the flow of the shortcut keys and change the Opacity shortcut keys are similar, but also through the number key, the difference is to hold down the SHIFT key and then press the corresponding number keys. such as 50% is 〖shift 5〗,80% is the 〖shift 8〗,45% 〖shift 45〗,1% is 〖shift. Note that the number key here must be a numeric key above the keyboard alphabet, which is not valid with the numeric keypad.

Now we want to turn the image into a blank, just like a new one. This time we can pass the history record. Think, if the whole image is filled with white, does not achieve the same effect? The Fill command is 〖shift f5〗 the menu "edit Fill". Use white in the content, the mode is normal, the opacity is 100%, the whole image can be filled after being determined. The following figure.

This type of padding is cumbersome because you also need to operate in the settings box. There is a shortcut key can be filled directly with the foreground color, it is 〖alt Delete〗 or 〖alt Backspace〗,backspace is located at the top of the key to the backspace.

Then combine the previous learning of several shortcuts, with a white Fill method is: First press 〖d〗 to set the color to the default before the black and white, and then press 〖x〗 the foreground color into white, and finally press 〖alt Delete〗 complete the foreground color fill. In fact, you can also use the shortcut key directly fill the background color, it

Then combine the previous learning of several shortcuts, with a white Fill method is: First press 〖d〗 to set the color to the default before the black and white, and then press 〖x〗 the foreground color into white, and finally press 〖alt Delete〗 complete the foreground color fill. In fact, you can also use the shortcut key directly fill the background color, it is 〖ctrl Delete〗 or 〖ctrl Backspace〗, so the above operation can actually be simplified into 〖d〗, 〖ctrl Delete〗.

0318 now look at what is the hardness of the brush. First we enlarge the brush diameter a little. The enlarged method can be changed by pulling the slider in the brush preset as before. You can also use the shortcut key 〖]〗, which is the closing bracket. The shortcut key to reduce the brush diameter is the left bracket 〖[〗. The number of brush diameters added or reduced using shortcut keys is not always 1. Within 10 pixels is the 1,10~100 pixel between 10, between 100~200 is 25, between 200~300 is 50,300 above is 100. The maximum diameter is 2500 (a later version of Photoshop may break this limit). So if you want to use a diameter size of 12 pixels, you need to pull the slider or enter a number. Use shortcut keys to enlarge or shrink the brush if the mouse is in the image, the cursor will also zoom in or out.

Now set the brush diameter of 30, hardness of 100%, with black in the left part of the image, so that a circle appears. Then the brush hardness is set to 50% on the right click again, and then set to 0% click Third. A different three circles will appear, as shown in the following figure.

The first round of the edge is the most tough, if the real life of the brush, this is like a brush vigorously place down, the third seems to use only a small force, the edge looks more virtual. The second one is in the middle state. Therefore, the soft hardness of the brush in effect on the performance of the edge of the virtual (also known as feather) degree. The softer brushes will look smaller because of the edge blur.

Changing the soft and hard shortcut keys for brushes is 〖shift [and 〖shift]〗, each time changes 25%. Note that when you use a shortcut to soften a brush, the mouse cursor shrinks slightly, not because the diameter shrinks. The reason for the reduction is that you will understand the transparency of the constituency after you have studied the selection in later courses.

After trying out the opacity and flow effect, let's look at the airbrush effect. Press the Airbrush button on the right side of the flow control in the public bar so that the gun is started. The airbrush is a way rather than a stand-alone tool (used as a stand-alone tool in earlier versions of Photoshop), which is a way of using the brush that increases the color concentration as it stays longer.

Now we choose a 30-pixel brush with a hardness of 0%, opacity and flow of 100%. When the airbrush is turned on, click on the left side of the image and hold the mouse for about 2 seconds on the right side of the image. Will form an image similar to the following figure.

can also reduce the flow of some, so that the image dragged on the wall as if spray paint, in a place to stay longer, the place where the paint is thicker, the scope is larger. It is obvious that the point on the right side of the diagram is over 30 pixels. You can also try to open the gun when the drop in flow, such as 15%, so the effect of spraying will be softer. This seems to give us a feeling that the effect of opacity and flow is almost the same, in some cases it seems to be true, but we should remember that the two principles are completely different.

Note that when the spray gun mode is turned on, the flow of the accelerator key no longer need to press SHIFT, directly enter the number. The Opacity shortcut keys need to press SHIFT instead. Turn off the airbrush in a way that restores the previous. This is also a setting for Photoshop to be considerate to users, because the most likely thing to change when using an airbrush is the flow size and no longer the opacity.

Now we need to draw a T-word graph, the following left figure, how to draw to maintain a straight line?

You can draw a horizontal or vertical line when you hold down SHIFT while the drawing begins, and you keep holding down the SHIFT key during the drawing. Note To continue the mouse release, and then release shift. If you loosen up halfway then the drawing will not be able to maintain a straight line. Vertical lines are the same. Hold down SHIFT and draw.

But if you draw the first horizontal line from left to right, and then hold down shift to draw the second vertical line, you may see the effect of the next diagram, the end of the first stroke and the starting point of the second pen are connected together. This is caused by another usage of the SHIFT key on the brush, and to avoid this, switch to the other tool and then switch back after the first pen is completed. You can also press 〖ctrl ALT Z〗 to undo a step and then draw a vertical line after the end point connection.

Hold down shift to maintain a horizontal or vertical line, and if you want to draw a straight line at any angle, you can click at the starting point, then hold down SHIFT and click the finish line to complete the two-point connection. This is also the reason why the error occurred in the previous example. Hold down the SHIFT key continuously to draw straight lines without having to set the start and end points each time, because the end of the first line is also the starting point for the second line. Now try to draw the shape of the bottom right figure. It is important to note that if the spacing option for the brush setting (which will be described later in the tutorial) is not turned on, you cannot draw a line through this method.

The set brush diameter and hardness can be stored so that you do not need to reset it when you use it again. Now let's just set a main diameter and hardness and click the New button in the Brush Preset window (the green circle at the bottom left).

You can also click on the button above the New button to choose a "fresh brush preset", there will be a storage dialog box, the default will be the diameter and hardness as the name, hardness is less than 50% when the soft angle, large equals 50% when called sharp angle. You can also enter the name you want. The following is the right figure. The saved brush will be at the end of the preset list.
