As a basic geometric body, the sphere is an object that beginners of art must draw. It can intuitively express the characteristics of the "five tones" and is also the basis for mouse drawing or hand drawing in our code design software.
Figure 2.1-19 shows the effect of the example in this section.

The following is the production method and process of the example:
Press the Ctrl+N key combination on the keyboard, or execute the "File → New" command on the menu bar to open the "New" dialog box. The settings are shown in Figure 2.1-20.
Figure 2.1-20 Settings of the "New" dialog box for spheres
Set the foreground color and background color to light gray and white respectively, as shown in Figure 2.1-21
Figure 2.1-21 Setting the foreground and background colors
Press the Ctrl+R key combination on the keyboard to open the ruler, drag out the horizontal and vertical auxiliary lines from the ruler, take their intersection as the center of the circle, hold down the Alt+Shift keys, press the left mouse button and drag Move to get a circular selection. Select the "Gradient Tool" (shortcut key G) and set this tool on the option bar, as shown in Figure 2.1-22. Create a new layer and use the "Gradient Tool" to create a gradient within the circular selection, as shown in Figure 2.1-23.

At this time, the sphere already has three tones: "highlight", "bright part" and "dark part". Next, we continue to draw its "reflective" tone.
Select the "Dodge Tool" (shortcut key O) and set the "Exposure" to 30% on the option bar, as shown in Figure 2.1-24.

Right-click the document window and set the main diameter and hardness of the "Dodge Tool" as shown in Figure 2.1-25.

Use the "Dodge Tool" to paint the lower right direction of the sphere to create a "reflective" effect, as shown in Figure 2.1-26.
