图片你或你的学生在绘画时是否特别拘谨？我知道我就是！！让一位“拘谨型”画家放松下来非常困难——这需要反复练习与不断试错。
本高中美术绘画课是一次极佳的放松训练，旨在帮助学生放下控制欲、自由挥洒。我们此前已学习过成人面部的准确比例，随后便进入正负空间复习环节，并尝试多种水彩技法（过程超级有趣！）。
教学资源： 《用爱做小事》之简易水彩肖像教程，http://www.craftster.org/forum/index.php?topic=301135.（文末附更多资源与范例）
总体教学目标： 学生将复习正空间与负空间概念；使用图片编辑软件将肖像照片转换为高对比明度图像（仅黑白，不含灰阶）；尝试多种水彩技法，包括倾倒、遮盖与喷溅。
第一课：极致正负空间肖像
教学流程：
- 空间定义——美术基本元素之一，指物体上方、下方、之间、内部及周围所存在的空余区域或面积。
- 正空间——作品中具象的形状或形体（即主体物）
- 负空间——主体物之间及周围的空白或非重点区域
- 展示明度高对比图像（仅黑白两色）。
- 教师示范操作步骤：
- 将照片转为数字图像（若为纸质照片，需扫描或拍摄数码照片）。
- 使用图片编辑软件将图像处理为纯黑白图像（非灰度图）。下方提供iPad端分步操作指南，软件为 www.FreeOnlinePhotoEditor.com
课堂活动：（3–4节45分钟课时）图像编辑与肖像绘制
准确绘制一幅人物肖像（肩部以上），视角为正面或三分之二侧面。图像须呈现高对比明度（仅黑白两色）。
操作步骤：
- 寻找或拍摄一张人物照片（肩部以上），视角为正面或三分之二侧面。
- 将照片转为数字图像（若为纸质照片，需扫描或拍摄数码照片）。
- 使用图片编辑软件将图像处理为纯黑白图像（非灰度图）。
- www.FreeOnlinePhotoEditor.com
操作指南（iPad版）：
- 选取一张照片（正面或¾侧面）
- 将照片保存至“照片”App（长按图片，直至弹出“保存图像”按钮）
- 打开 www.FreeOnlinePhotoEditor.com
- 点击“浏览”，从照片图库中选择；点击“确定”
- 点击“颜色”→“黑白”
- 点击“基础”→“亮度/对比度”
- 调整亮度与对比度，直至获得满意效果
- 保存图像——长按图片，直至弹出“保存图像”按钮，点击“保存图像”
- 打印图像——打开“照片”App，选中图片，点击分享图标，选择打印机
- 将图像打印为8×10英寸尺寸。
- 在10×15英寸水彩纸上（尺寸为8×10英寸的1.5倍）仅用轮廓线绘制该肖像。
所需材料： 计算机或平板电脑、10×15英寸水彩纸（推荐140磅）——康颂装订水彩本，30张
、铅笔
第二课：水彩倾倒实验（2–3节45分钟课时）
教学目标： 学生将尝试水彩倾倒技法；探索不同色彩组合的效果，或实现预设视觉效果。
教学流程：教师示范指导——水彩实验与倾倒练习工作表
- 如何使用遮盖液“留白”——遮盖液与橡胶水泥的使用方法
- 湿画法（湿底上着色，湿颜料滴入湿底）
- 干画法（湿颜料涂于干底）
- 湿底撒盐
- 喷溅
- 上色前后向纸面喷水
- 尝试水彩倾倒技法
- 尝试色彩组合（注意：邻近色协调融合效果佳——和谐感；互补色混合则产生低饱和明度——强调对比、营造深沉氛围）
所需材料： 管状液态水彩或液态水彩——萨克斯浓缩可洗液态水彩颜料，8盎司，8色套装，混色款
、用于倾倒的小塑料杯（每位学生3–5个）、遮盖液、橡胶水泥、牙刷或义齿刷、水彩实验与倾倒练习工作表（打印于水彩纸上，裁切为8.5×11英寸）
项目目标：以正面或三分之二侧面视角，准确绘制一幅人物肖像；通过营造高对比度图像，强化正形与负形的视觉关系；运用多种水彩技法（留白液与橡皮水泥、倾倒法、撒盐法、喷溅法）为肖像上色。
操作步骤：
- 选取一张正面或三分之二侧面的人物照片。
- 使用图片编辑软件，增强正形与负形的对比，制作高对比度图像。
- 用铅笔在水彩纸上大幅绘制该图像。
-
在所有需保持白色的部分涂覆留白液与橡皮水泥。**提示：橡皮水泥需涂2–3遍——单层厚度不足！！！另请注意留白液品牌——我们此前使用的型号会使纸面泛黄 🙁 
-
运用以下多种水彩技法完成肖像绘制：
- 留白液与橡皮水泥（覆盖所有需留白区域）
- 倾倒法
- 滴流法
- 喷溅法
- 撒盐法
- 喷水法
- 喷溅法
- 最后，待画面完全干燥后，清除留白液。
- 可选步骤：用画笔勾勒局部轮廓；适量添加印度墨水以增强表现力（例如刻画眼睛）——请慎用。

imageAre you or your students super tight when it comes to painting? I know I am!! Trying to loosen up a “tight” painter is HARD to do-it takes practice, trial & error.
This HS art painting lesson is a great exercise in loosening up and letting go of control. We learned how to draw correct adult facial proportions PRIOR to this project and then jumped into reviewing Positive & Negative Space and experimenting with watercolors (which was super FUN!).
Resources: Easy Watercolor Portrait by Do Small Things with Love, http://www.craftster.org/forum/index.php?topic=301135. (more resources/examples at end of post)
Overall Objectives: Students will review positive and negative space. The will use a photo editing program to transform a portrait to show high contrast values (black or white only). They will experiment with different watercolor techniques such as pouring, masking and splattering.
Lesson 1: Extreme Positive & Negative Space Portrait
Delivery:
- Define Space-the element of art that refers to the emptiness or area above, below, between, within, and around objects.
- Positive Space-the shapes or forms (main objects) in an artwork
- Negative Space– the empty or non-interesting space between and around the main objects
- Show images with high contrast of values (black or white only).
- Teacher Guided Demonstration on how to:
- Turn a picture into a digital image (if photo is in print form-scan or take digital photo).
- Use photo editing software to reduce the image to a black and white image (not gray-scale). Step by step instructions below for iPad using www.FreeOnlinePhotoEditor.com

- Wet on Wet, Dripping wet into wet
- Wet on Dry
- Salt in Wet
- Splatter
- Spray the paper with water before and after applying the paint

Apply Masking Fluid & Rubber Cement anywhere you want to stay WHITE. **TIP: Apply 2-3 coats of the Rubber Cement. One layer is not thick enough!!! Also, be careful of the brand of masking fluid-the kind we used stained the paper yellow 🙁
-
Use various watercolor techniques to paint the portrait:
- Masking Fluid & Rubber Cement (on ALL areas to stay white)
- Pouring
