你曾仔细观察过一面卷动的星条旗吗?
你是否看到笔直的条纹向前、向后弯曲?
你是否看到白色条纹变暗并向下“沉降”?
请观看下方视频,并密切留意……

这些艺术家在画作中将星条旗表现为扁平图像。
而我们希望在课堂中将星条旗转化为一种视错觉作品。
我们要营造出旗帜正在卷动的视觉假象。

为实现这一错觉,我们必须运用轮廓线(使线条发生弯曲)
来描绘旗帜,并运用明度(value)。

在纸上画出4条垂直线,它们彼此间距逐渐收窄(但不相交)。
在每一条间隔的垂直列中画出弧形线。
将纸张旋转方向,使新画的线条朝相反方向弯曲,形成对向轮廓线。确保新旧线条端点准确对接。
在左上角留出空白区域用于绘制星星。
绘制一条弯曲的轮廓辅助线,作为在旗帜空白区域中绘制星星的基准线。

——
沿轮廓线着色。
用红色蜡笔轻柔涂色。
让色彩走向随线条弯曲而变化。

通过在靠近垂直线处加重红色蜡笔压力,添加阴影。

用蓝色蜡笔沿白色条纹的垂直线轻轻涂抹,表现阴影。
——也可选用灰色或黑色替代。

用力用蓝色填满星星后方区域。

Have you even watch a furling flag closely?
did you see the straight stripes bend forward and back?
Did you see the white stripes get dark and they decent?
Watch here and pay close attention...

THese artist show the flag as flat in their paintings.

In order to create this illusion, we must use CONTOUR LINE (bend our lines)
in the flag and use VALUE.

Draw 4 vertical lines on paper that get closer together (but not touching) on paper.
Draw curved lines in every other vertical column.
Turn paper other way to make lines contouring in opposing direction. Make sure they match up with opposing lines, touching ends.
Leave the corner open for stars.
Dra a bent contour guideline to draw stars on the open space of flag.

Elijah & Michael shading...
Color with the contour.
Color softly with red crayon.
Bend your coloring with the bend of the line.

Add shadows by pressing harder close to the bertical lines with the red crayon.

Use the blue crayon lightly along the white stripe's vertical line to show shadow.
-alternative color using grey or black.

Color behind stars hard with blue.
