Grapes are known as the agate among fruits, with beautiful appearance and delicious taste. In this hot summer, let’s use Photoshop to draw a bunch of crystal grapes!
In the process of making this grape, few advanced techniques such as Photoshop filters and layer blending modes were used. Mainly through the depiction of this bunch of grapes, I will introduce in detail the light and shadow effects in the Photoshop cs2 mouse hand-drawing process, as well as the expression of the object texture. . At the same time, we also use this example to explain composition and coloring in detail, as well as the application of the tools in the software in actual painting.
During the painting process, we must pay attention to the overall situation, analyze the environment in which the painting object is located, the impact of environmental color on the painting object, and the possible light and shadow changes of the object in the environment.
The entire bunch of grapes can be viewed as a whole, and the light and shadow changes of the object can be roughly summarized. Then we will detail the individual grape grains.
Figure 2.2-1 Completed renderings
Observing this bunch of grapes carefully, it is not difficult to find that although the grape grains are actually similar, they cannot be copied when painting. Because the grape grains grow in different locations and receive different levels of light, they must be treated individually during the drawing process.
Figure 2.2-2 is the analysis of light source orientation.
Figure 2.2-2 The direction of the light source is behind the upper left corner of the grapes
The picture below is an analysis of the five tones of grapes as a whole. Because there are no objects around the grapes in the picture that can reflect their projection. Therefore, the tone of projection is not shown in the picture, as shown in Figure 2.2-3. But it’s not that the grape violates the law of the five tones. Its projection should be reflected on an object outside the scope of the picture, such as a certain part on the ground.
Figure 2.2-3 Four tones reflected on grapes
Grapes are composed of individual grape grains, and each grape grain also reflects the changes of different five tones. The parts pointed by the straight lines in the picture below mark the five tones on the grape grains (Figure 2.2-4).
Figure 2.2-4 The five tones on individual grapes
To facilitate characterization, find the mid-tone of the grape. After observation, it was determined that the color was grass green with RGB values of 191, 220, and 98 (hereinafter referred to as "grass green" in this section).
The grape grains on the light-receiving surface of the overall five tones basically have relatively bright highlights and should be covered with white with higher opacity. The grape grains at the junction of light and dark are the darkest, so use the Burn Tool to erase the "dark green" color. Some grape grains are affected by the ambient color and appear "ochre", so use the "Brush Tool" with a lower opacity to paint them. Make the dark parts a little lighter and keep the fill color unchanged. The grape grains in the reflective part are brighter in color, so use the "Dodge Tool" to lightly apply them.
After analysis, we start to produce:
Open "File" on the menu bar and select the "New" command. Or press the Ctrl+N key combination on the keyboard to create a new file and name it "Grape". See Figure 2.2-5 for other settings.

Figure 2.2-7 New layer dialog box
In the "New Layer" dialog box, you can directly set the layer's blending mode and "opacity" and other parameters.
Let's draw the first grape grain in the upper left corner. This grapevine is basically backlit, but the grapes are translucent fruits. After the light comes in, the surrounding area of the grape seed appears "grass green", and the middle part is where the grape seed grows, which is opaque and darker in color. Coupled with the changes in the five tones, the performance of the grape grains is basically no problem.
Use the "Elliptical Marquee Tool" (shortcut key M) to create a selection, set the foreground color to the "grass green" set above, and press the Alt+BackSpace or Alt+Delete key combination on the keyboard to fill the foreground color. Execute the "Edit→Transform→Deformation Tool" command on the menu bar and drag the control points and control rods. The effect is shown in Figure 2.2-8.
Figure 2.2-8 Use the deformation tool to deform the grape grains
Tip: The deformation tool is very commonly used and you can define a shortcut key for it. Many Ctrl and numeric key combination software are not used, so you can choose from this type of combination. Or use it by selecting "Transform" from the right-click menu after free transformation.
Press the Ctrl+T key combination on the keyboard to enter the free transformation state and rotate the graphic to the following angle, as shown in Figure 2.2-9.

Figure 2.2-11 The effect after modification using the burn/dodge tool
Set the foreground color to dark green, and use a smaller diameter, harder brush to draw a dot on the bottom of the grape. The first grape is complete.
The second grape seed is not completely backlit. Its side is illuminated by the light source, and the light reflected to the observer's eyes is scattered light. Therefore, it will not be too bright and will not produce a light transmission effect. Next to the first grape seed, Partially reflects its projection, as shown in Figure 2.2-13.
Figure 2.2-13 Fill the circular selection with “grass green”
Figure 2.2-14 The completed effect of the second grape grain
Draw the third grape grain in the same way as the first grape grain, as shown in Figure 2.2-15.
Figure 2.2-15 The third grape grain completed effect
The fourth grape grain is drawn similarly to the second one. The fifth grape grain needs to be layered under the first four. This grape grain receives more light, so the highlight part is brighter. The backlight part shows an "ocher" color due to the influence of the color of the light source and the color of the environment.
Without canceling the selection, select the "Brush Tool" (shortcut key B), right-click in the "Document Window", and set the main diameter of the brush to be larger and the hardness to 0% in the pop-up palette. Set the "foreground color" to an "ocher" color with lower lightness and lower purity, and set the brush "opacity" to 30%, as shown in Figure 2.2-16. Apply evenly within the selected area, as shown in Figure 2.2-17.

Next draw the sixth grape grain. The areas next to other grape grains reflect their reflections, as shown in Figure 2.2-18.
Figure 2.2-18 The finished effect of the sixth grape grain
This is a grape grain with a relatively obvious highlight, and the highlight is at the location where the light source shines. We create a new layer on the grape grains, use the "Rectangular Marquee Tool" (shortcut key M), and set the Boolean mode to Collection, as shown in Figure 2.2-19.
