Lesson Summary
This lesson focuses on refining students' shading techniques through the creation of a tonal scale on kraft paper. Building on this foundation, students will delve into understanding the interplay of light and shadow, applying their knowledge to render geometric shapes with a range of tones and highlights. This exercise aims to enhance students' grasp of how light operates, ultimately elevating their drawing and painting skills.
Understanding Lighting Principles
Comprehending the principles of light is fundamental in visual art, as visibility relies on light. People perceive the world through light rays bouncing off objects and reaching their eyes. By understanding how lighting conditions affect the visible environment, artists can skillfully incorporate these nuances into their work. A thorough grasp of lighting principles significantly improves an artist's drawing and painting abilities.
Discussion
What effect does the technique of drawing on toned paper produce?
Briefly explain how people see the world through light.
Why is understanding lighting principles important for artists?
What to do
Materials: Tonal Template on Kraft Paper, Black and White Colored Pencils, Eraser
Tonal Scale:
Utilize the provided template to shade a 7-increment tonal scale on your paper, ranging from solid black to white.
Ensure even distribution of each tone, with the 4th tonal value marking the 50% value — The tone of the paper.
Shade Geometric Shapes:
Shade each geometric shape, establishing a consistent light source for all basic shapes.
Customize shading based on the surface shape of each geometric form.
Highlights:
Upon completing the shading process, enhance the geometric shapes by adding highlights using a white pencil crayons.
Terminology
Value Scale — Allows artists to understand and organize different shades from light to dark. It includes a graduated scale from the lightest value (white) to the darkest value (black) and various gray tones in between.
Light Source — Things that produces natural or artificial light.
Form Shadow — The part of an object that is not in contact with direct light.
Core Shadow — The very darkest point within the Form Shadow where there is little light hitting the surface.
Cast Shadow — A dark area, usually on a flat surface where light is blocked by an object.
Reflected Light — Light that bounces off surfaces and indirectly illuminates an object.
Highlight — The exact point where light hits an object, perpendicular to its surface. It is the very lightest part of an object.
