THE VOCABULARY OF INTRODUCTORY TERMS 

cast shadow 

The dark area that occurs on a surface as a result of something being placed between that surface and a light source.


THE VOCABULARY OF INTRODUCTORY TERMS ď Ž

Chiaroscuro (Chiaroscuro means light and dark in Italian.)

I. Distribution of light and dark in a picture. 2. A technique of representation that blends light and shade gradually to create the illusion of three-dimensional objects in space or atmosphere.


THE VOCABULARY OF INTRODUCTORY TERMS 

chromatic (value) 

The value (relative degree of lightness or darkness) demonstrated by a given color.


THE VOCABULARY OF INTRODUCTORY TERMS 

closed-value composition 

Composition in which values are limited by the edges or boundaries of shapes.


THE VOCABULARY OF INTRODUCTORY TERMS 

decorative (value) 

Ornamenting or enriching but, more importantly in art, stressing the twodimensional nature of an artwork or any of its elements. Decorative art emphasizes the essential flatness of a surface.


THE VOCABULARY OF INTRODUCTORY TERMS 

The key selected sets the mood of the work.


Introduction to VALUE Relationships


Introduction to VALUE Relationships ď Ž

Value can be created by placing lines of the same or different qualities alongside or across each other to produce generalized areas of value.


Introduction to VALUE Relationships 

Value applied will create distinguishable shapes. Shadows and Highlight  Abstract textures 

Ex. Delicately drawn lines created values.


Introduction to VALUE Relationships ď Ž

The degree of Line Concentration indicates value of the subject.


Introduction to VALUE Relationships ď Ž

The degree of Line Concentration indicates value of the subject.


Introduction to VALUE Relationships 

CHROMATIC VALUE 

The lightness and darkness of a color.


Descriptive Uses of VALUE 

Creating objects, shapes and space.

Local VALUES Naturally occurring values.

Descriptive qualities Psychological, Emotional, and Dramatic expressions.


Descriptive Uses of VALUE ď Ž

ď Ž

Objects cannot receive light from all directions at the same time. A solid object gets more light from one side than another because that side is closer to the light source.


Descriptive Uses of VALUE 

 

Objects cannot receive light from all directions at the same time. Spherical surface  Even flow Intersecting planes  Sudden contrast


Descriptive Uses of VALUE 

Spherical surface  Even flow Intersecting planes  Sudden contrast


Descriptive Uses of VALUE 

CAST SHADOWS – Dark areas that occur on an object or a surface when a shape is placed between it and the light source.


Descriptive Uses of VALUE


Descriptive Uses of VALUE 

CHIAROSCURO 

Giving emphasis to light and shadow.


Expressive Uses of Values 

Balance between light and dark. Dark  Atmosphere of gloom, mystery, drama or menace. Light  Opposite
