明度(VALUE)

定义:明度指一种颜色或灰度的深浅程度。
明度可施加于二维形体(SHAPE)上,使其呈现为三维立体造型(FORM)。
这称为明暗/排线(SHADING)。

以下是添加明暗/排线前后的形体示例(使用铅笔绘制)。


绘制明度时,应做到:
平滑(Smooth)、均匀(Even)、有对比(Contrast)。
请用 S.E.C. 法检查你的明度效果。
本练习表是通过多种方式练习明度色阶的绝佳工具。
你可以打印使用,也可自行绘制……


多数初学者艺术家使用铅笔、彩铅或蜡笔进行明暗/排线。
这是最易上手的方式,因其依靠力度(pressure)控制明暗深浅。


进阶艺术家可能更倾向挑战性更高的明暗/排线方式:
钢笔与墨水(PEN and INK)。



这种方式依赖线条或图案的疏密间距,而非力度。
线条或图案越密集,明度越深;
线条或图案越稀疏,明度越浅。
最常用技法包括:
平行排线(Hatching)
交叉排线(Cross Hatching)
点绘(Stippling) 与 涂 scribble(Scribbling)。
但远不止这些!!!……

爱德华·戈里(Edward Gorey)——插画家,钢笔与墨水大师



以下是摩根老师(Mrs. Morgan)作品集中使用钢笔与墨水绘制的部分范例:
你能辨认出其中运用了哪些技法?




色彩(COLOR) 同样具有明度。
若将以下色彩纳入明度色阶中,它们应按怎样的明度顺序排列?



以下是摩根老师作品集中运用色彩明度创作的艺术作品示例。

另需注意:
每种颜色均可通过加白变为浅色调(TINT),或通过加黑变为深色调(SHADE),
从而生成自身更深或更浅的版本。

开始绘制明度色阶前,请先观看此 S.E.C. 视频……它将指导你如何绘制平滑、均匀、有对比(SEC) 的明度色阶。
在你的速写本中,以 “明度(VALUE)” 为标题记录以下内容:
定义:一种颜色或色相所能达到的明暗程度。
按明度由浅至深(或由深至浅)排列,可形成视觉上的秩序感。
将明度施加于二维形体(SHAPE),可使其呈现为三维立体造型(FORM)。
形体上的明度/排线效果,取决于光源位置(LIGHT SOURCE)。


请为每种媒介分别绘制一条明度色阶:
要求做到平滑(单向运笔)、均匀(各阶明度分布均等)、有对比(包含最深与最浅两极)。
媒介包括:铅笔、彩铅、蜡笔、墨水(共 4 种,墨水需体现 4 种不同技法)。
请注意:铅笔、彩铅与蜡笔依靠力度(PRESSURE)表现明度;
而墨水则需依靠线条/图案的疏密(SPACING)或设计形式来表现明度。

VALUE

DEFINITION: VALUE is the darkness or lightness of a color or greyscale.
Value can be use on a 2D SHAPE to make it appear as a 3D FORM.
This is called SHADING.

Here is an example of shapes before and after adding Value with pencil.


When you create value, it should be
Smooth, Even, and have Contrast.
Take a S.E.C. to check your values.
This worksheet is a wonderful way to practice your value scales in a variety of ways.
You can print it or make your own scales...


Most beginner artists shade with PENCIL, Colored Pencil, or Crayon.
This is the easiest way to shade because it uses pressure to create darks and lights.


Advance artist may prefer the more challenging way to shade, which is with
PEN and INK.



This does require spacing of lines or patterns rather than pressure.
The closer the lines and patterns, the darker the value.
The further apart the lines or patterns, the lighter the value.
The most used techniques are:
Hatching
Cross Hatching
Stippling and Scribbling.
BUT there's more!!!....


Video Tips on creating INK VALUE SCALES.

Edward Gorey- Illustrator, Master of Pen and Ink



Here are some examples from Mrs. Morgan's Portfolio using pen and ink :
What techniques can you find?




COLOR
also has Values.
What order would these colors goin in if in a VALUE SCALE?



Here is an example of using value of color to create Art
from Mrs. Morgan's portfolio

ALSO
Each color can become a TINT (adding white) or a SHADE (adding black)
to create a darker or lighter version if itself.

Take a S.E.C. to watch this before you begin with your value scales… It will show you how to create Smooth, Even, and Contrasting (SEC) Value Scales. IN YOUR JOURNAL VALUE
Definition- How Light or Dark a color or hue can be.
Values in order on a scale can show visual organization.
VALUE added to a 2 dimensional SHAPE can make it appear as a 3 dimensional FORM.
Value/Shading on a shape changes according to the LIGHT SOURCE.


Create a Smooth (1 direction) , Even (equal amount of each value), and Contrasting (darkest and lightest) Make a VALUE SCALE for each medium:
pencil, colored pencil, crayon, and ink (4 techniques).
Note that PENCIL, Colored Pencil, and crayon use PRESSURE to create VALUE.
In contrast, INK requires SPACING or lines/designs to create VALUE.
