I would like to note that Adobe Photoshop is not for painting, but for editing images. Therefore, you will not be able to draw anything you want with brush tool. More often than not, you will need to create new based on existing images. However, the brush is very important.
Drawing tools let you create arbitrary lines, simulating various real instruments. To drawing tools include:
1) With Brush you can create lines with smooth, or blurred edges of the rigid lines of different forms.
2) Pencil creates rigid line, simulating a pencil. It belongs to the same group as the brush. That is, if you can not find this tool, click the small arrow next to the brush and select the pencil tool from the palette.
Each of these tools have options. The most important parameters that determine the appearance of lines, are the thickness and shape. You can assign brushes in different sizes and shape with the help of a palette Options. So, select your brush and look at this palette. Let’s consider the options from left to right.

In the first list with the image of a brush, there is a Tool Presets. It is present in the left side of the Options palette, regardless of which tool is selected. If you regularly use a tool with some specific parameters, for example, oval brush with a diameter of 45 pixels, in the mode of Multiply, you should save it as preset, so that a cause of the list. It is much easier than re-adjust every time the same parameters. Save preset can be as follows: Open the pop-up palette of harvest tools by clicking on the picture painted by the left side of the Palette Options. Then there are two ways:
1) Click on the image of a clean sheet and enter the name of preset. Then we can maintain the tool with the current settings as a preset.
2) Enter in menu presets palette. Do not remember how to do it? You need to click the black triangle in the circle in the upper right corner of the palette. In opened menu select the first item - New Tool Preset, and type the name of preset.

The next option is located next to the word Brush. He is responsible for setting the brush size and shape. If we open the list, it opens pop-up palette, shown in the figure, which you can select a brush from the list or adjust the diameter of the current. Note that there are brushes presets, rather than general tools. At the bottom of the menu that lists the group palette brush presets. For example, Assorted Brushes - art brush (I recommend them to open, it is very beautiful), Square Brushes - square brushes, etc.
In this menu, the following important commands:
Reset Brushes - remove opened brushes presets, replacing them in the brushes by default. It happens that after the tumultuous experiments can not find a normal round brush, then this will simply irreplaceable.
Load Brushes - brushes for download from the file at the end of the current list. By the way, brushes are stored in files with abr (Adobe BRushes - easy to remember). Standard brushes are stored at C: \ Program Files \ Adobe \ Photoshop_folder \ Presets \ Brushes \ *. ABR
Save Brushes - save all the brushes from the current list in a single file.
Replace Brushes - download brushes from a file instead of the current.

A now try to reproduce this image. You dont have be a painter, have little orientation to the variety of brushes Photoshop.
Next Palette Options Mode parameter determines the mode of paint brushes. On the modes will be discussed below.
Opacity - defines the opacity of the brush.
Flow - this parameter has absolutely the same parameters opacity. But, of course, that the creators of Photoshop would not let such nonsense, so the differences are there. If you are not releasing the mouse button, hold the brush a few times on the same location on the image, the colors literally thicken, ie transparency of the layer caused by each will be striving to complete the opacity (if you want you can read again). As you guessed, in the case of opacity, how many times the brush is not occurring (of course, if you do not release the mouse) caused by the transparency of the layer does not change.
Right icon is transferred to the brush aerograph (airbrush). This mode differs from the conventional view that the paint as it is sprayed. This seems to work sprayer.
Palette Brushes.
And last but not least, the option in the right pane opens the palette Brushes. After opening the Brushes palette eye just run. But we will not succumb to the temptation to try everything at once, and explore the range consistently. On the left side of the palette, you will see a variety of options to customize the form of a brush stroke. Enumerate them briefly:

Brush Tip Shape - setting the brush shape.
Shape Dynamics - dynamic change in the form of a brush, in the smear.
Scattering - “spraying paint in the process of drawing.
Texture - texture overlay on the brush.
Dual Brush - the creation of a “double-brush.”
Color Dynamics - dynamic change of color in the stroke.
Other Dynamics - Other changes in brush in the smear.
Now stop for all of this in detail. The figure depicts the setting of Brush Tip Shape. Diameter - the diameter of the brush, Angle - the angle, Roundness - the degree of circularity.
For round and oval brushes, there is the option Hardness, defining the blurred edges. We want to create a form of the brush itself, rather than impose some abstract figures. This feature is also available! In the form with the scheme of a brush, there are bold points, which are the keys to form a brush. Move bold point, the form of a brush can be changed from round to elliptical, moving points up or down. Also, the scheme has an arrow that points to the direction of the ellipse. Naturally, there is no experiments do not.
Parameter Spacing helps paint strokes jerky. Spacing - the distance between the strokes in the smear, which is measured as a percentage from the diameter of the brush. To all of this became clear, take a look at the picture.

Shape Dynamics is such settings: Size Jitter (random changes in size), Angle Jitter (random change of the angle), Roundness Jitter (random change of circularity).
Under each of these parameters have a list of Control, we choose, as changing this setting:
Off - do not change. For example, Size Jitter will randomly change its size in the dispersion, but no trend to the broadening or narrowing of the brush will not.
Fade - will disappear over a specified number of steps. Ie will be a tendency to decrease.
Pen Pressure - depending on the pressures on the pen. ”
Pen Tilt - depending on the inclination of the pen. In other words, from the direction of drawing.
Scattering has the parameters: Scatter, Both Axes - on both axes. Count (the degree of splashing), Count Jitter (random degree spray).

Texture - a texture can be scaled using the Scale, to strengthen and weaken its effect by means of Depth. Figure texture imposed on a round brush.
Dual Brush - sets the current brush shape smear, as selected in this option - the type of smear. The second brush will be texture for the first. The result can not but impress! On the picture on a round brush diameter 65 px brush imposed Grass diameter 134 px from the set of Assorted Brushes.
In Color Dynamics upper slider adjusts the shift from core to the background color in the stroke. Purity - the accuracy of the transfer of color.
Other Dynamics has parameters Opacity Jitter (variation of transparency) and Flow Jitter (variation of intensity). In the example Opacity Jitter = 0%, but the importance of Control = Fade. That is, the opacity of the brush decreases in the number of steps, which in this case is 50. With this admission, you can simulate the gradually dissolve in the background of smears brush.
Below are 5 flags:
Noise - the addition of noise to form a brush.
Wet Edges - imitation brush with wet edges.
Airbrush - aerograph mode.
Smoothing - Smoothing lines.
