Project 3: LIGHT ON SPHERE --DUE DATE: THURSDAY, October 13TH (at the beginning of class)

BEGINNING DRAWING ART 111-1 ASSIGNMENT SHEET
RELATIONSHIP OF LIGHT TO PLASTIC FORM
PRIMARY AND SECONDARY LIGHT ON SPHERE

MATERIALS:
• Graphite Pencils (Full Range)                       • Eraser
• ½ sheet of drawing paper                              • Ruler

SUBJECT MATTER:
• Sphere

GENERAL GOAL: Create a drawing that is the illusion of light defining plastic form.  Understand and locate the seven aspects of light to help create this illusion.

GENERAL INSTRUCTIONS:
• Allow the primary light source to (clamp light) to be the spot.

• Allow the secondary light source to be the ambient light.  Observe the sphere thinking of the negative shapes first when deciding how to compose the subject.

• Start your drawing thinking in terms of general to specific, first using 2h graphite (light marks) and work towards 3b graphite (darker marks).

• Once the composition is set on your paper, use your full range of graphite pencils to make a series of value transitions from light to dark.

• Using a range of values make shapes on your paper representing plastic form by using “open and closed form”, “gradient transitions”, and the “language of light”.

• By the end of your drawing process you should have represented the sphere integrating into an illusion of space and light.

GENERAL QUESTIONS FOR GRADING:
• Were the basic instructions understood and followed?
• Does the work fail to meet, meet, or exceed the basic requirements of the assignment?
• Were the proper materials used?

GRADING CRITERIA:
• Create the illusion of space and illusion of form (sphere).
Full range of values using hatched and cross hatched lines as definer of edges and complexity (rather than using smudged graphite).
• Accuracy (scale, position, continuity of edge).
• Composition (balance in scale of shapes)(originality).
• Craftsmanship


DUE DATE: THURSDAY, October 13TH (at the beginning of class)





Generic computer generated "light to form" illustration highlighting the phenomenon of light effecting a sphere.



Example of a Beginning Students drawing of light affecting form. 

Note the transitions of value and how the student created the illusion of light effecting form by using the techniques of hatching and cross hatching while building the appropriate values.
