通过铅笔压力控制明暗






用铅笔起稿,用记号笔/更深的颜色强调轮廓;
用水彩笔(黑色或纸色的深色调)进行明暗/排线;
用白色彩铅提亮高光……

挑战:尝试用墨水技法表现明暗

研究交叉轮廓线在不同视角下的变化
当中心点移动时,线条如何变化?




南瓜世界中存在多种形状
- 可尝试绘制高大、矮胖或细长的南瓜。
先确定基本形状,再添加轮廓线。

*运用重叠手法
将较小的南瓜画在前方,较高的南瓜置于后方;
后方南瓜的部分形体应被遮挡。

在你的
速写本中


练习用轮廓线绘制多种南瓜。
规划一幅含 3–5 个南瓜的构图,运用重叠与空间深度。
添加明暗/排线与投影,并加入创意细节。

开始绘制最终作品
我们将完成以下内容……
评分标准
3–5 个形态各异的南瓜 —— 10 分
画面饱满、充满空间 —— 10 分
重叠关系 —— 20 分
轮廓线 —— 20 分
明暗/排线(含投影)—— 20 分
高光 —— 10 分
中间调(纸面原色显露)—— 10 分
创意性 —— 10 分
使用彩色纸作画
你将用黑色/纸色的深色调表现明暗/排线(较暗区域),
用白色表现高光(较亮区域),
同时保留棕色/纸本色作为中间调(中等明度)。

- 绘制 3–5 个形态与尺寸各异的南瓜
(后方南瓜更大,且位置更靠近画面底部)

- 用铅笔起稿,以中心线为中性线,开始绘制轮廓线。

左侧轮廓向左弯曲,右侧轮廓向右弯曲,贴合南瓜外缘形状。

- 添加创意细节
(如叶片、昆虫、藤蔓等)



- 用强调色勾勒轮廓线

- 根据统一光源方向添加明暗/排线(我将光源设于右上角)。
使用黑色彩铅,或比纸色更深的同类色。

别忘了添加投影……

- 用白色辉柏嘉彩铅提亮高光。



想接受挑战吗?
- 用记号笔表现明暗/排线,用白色油漆笔提亮高光;
- 尝试不同背景纸张,改变整体效果。






你知道南瓜是怎么生长的吗!
你以为的“底部”,其实才是真正的顶部;
所谓“底部”中心,正是当初南瓜花生长的位置。

在这里观看它的生长过程……

What you think is the bottom is really the top.
The “bottom” center is where the
pumpkin blossom once grew.
