SHADE & SHADOW

By Eng. Wafaa Al-Hudifi

Shadow With & Without

Shadow is the darkness that results because an object

blocks light from hitting another object. Light from other

sources will change how the shadow appears. Often

shadow farther from the object will be less dark and

less crisp. In this image, notice that the light reflecting

from the pitcher brightens part of the shadow from the

block in front of it.

This is different than shade.

Shade is the dark part of an object that doesn’t receive

light. The front of a pitcher, for example, reflects light

toward the viewer and the back side is in shade. The

pitcher casts a shadow on the ground and wall.

The 4 ELEMENTS of a form

Elements – highlight, halftone, core shadow, reflected light, and cast shadow. It’s an essential skill to be able to quickly identify each element on a given object

and to execute each accurately. A. Highlight B. Halftone C. Core Shadow D. Reflected Light E. Cast Shadow

A Quick Anatomy Of Light And Shadow In the simple diagram below, we can see that the light source is coming from the left. The highlight is where the light is strongest, and the shadows fall on the side furthest from the light source. The appearance of light and shadow tells us a lot about the surfaces and textures in the image.

The letter ‘B’ means ‘bold’ or

‘black’, and signals a soft lead in the

pencil, which adds a lot of lead to the

paper, creating darker shades.

Similar to ‘H’ grades, the number next

to the letter signals how soft the lead is,

with 9B being the softest, and

therefore darkest.

The best pencil is 2B

Shading Technique

Value Scale

A value scale is used by artist to show the variety of shades that can

be made with graphite. This scale is a tool the artist uses to make

sure their drawings have a more realistic and dynamic look.

The value scale is a system of organizing values. It consists of ten values ranging from white to black, with several shades of gray in between.

Example

Casting Method

Angle of Light source

It depends on the light source but the best angle is 45 degree.

Shadow Edge

Below are two photographs to illustrate the subtle differences in the shadow

strengths when I altered the lighting slightly.

, because it’s not diffused it has created a The first one used direct sunlight

harder, more solid shadow line and cast shadow.

Also see how you can judge the angle of the sun via the length of the cast

shadow and the bright highlight.
