我很高兴在此下方展示 theartproject chad brown 制作的一则精彩视频教程。Chad Brown 是一位美术教师，他为自己的学生专门制作了这则教程，用以讲解课堂上的这一课题。他拍摄了整个创作过程的视频，学生们则依据该视频完成自己的作品。这是一个极佳的教学创意，我也期待看到 Chad 的其他视频。请观看视频，并享受其中！

为了理解素描中的明暗效果，训练对空间深度的感知非常有帮助。在平面素描上添加阴影，有助于我们感知画面所呈现的三维纵深效果。这有点像一种“魔法”：只有当阴影落在恰当的位置时，我们才能分辨出不同的层次。

我与七年级学生共同完成了这幅素描。我们首先用铅笔绘制第一层：一种带圆角的、类似丝带状的多孔膜结构。接着勾勒出数层这样的膜结构，并用彩铅为其添加明暗。关键技巧在于：每当一条丝带位于另一条丝带之下时，就在其上方丝带的下方位置绘制投影。上方丝带在下方丝带上投下阴影，从而清晰展现各层之间的纵深关系。

我们为每一层使用了不同颜色；在绘制完 3–4 层后，再用黑色记号笔涂满背景，以进一步强化纵深感。

I’m glad to show here below a great video tutorial from theartproject chad brown. Chad Brown is an art teacher who created this tutorial for his students, to explain this project in his class. He has made the video of the process and his students use it to make their pieces. This is a great idea and I look forward to watching other Chad’s video. Have a look at he video and enjoy!

In order to comprehend the shading effects in a drawing, it’s very useful working on the perception of the depth. Adding shadows on a flat drawing helps our perception in seeing the three-dimensional effects of the depth. It’s a sort of “magic”: we can understand the different layers just if the shadows are in the right spots.

I created this drawing with students of grade 7th. We started drawing the first layer with a pencil. We drew some kind of perforated membrane, like a ribbon with rounded corners. We have sketched few layers of these membrane and we have shaded them with colored pencils. The trick is to create a shadow every time that a ribbon goes under another one. The ribbon above creates a cast shadow on the ribbon below, so we can see the depth of the layers.

We used a different color for every layer: after we have drawn 3-4 layers we have colored the background with a black marker, to emphasize the depth.
