Lecture on Sighting Technique in Drawing

Introduction to Sighting

• Definition: Sighting is a drawing technique used since the 15th century, during the Renaissance period.
• Purpose: Helps in maintaining the correct proportions while drawing different objects.

Demonstration Overview

• The technique will be demonstrated using three gourds as examples.
• The goal is to learn how to keep objects in proportion relative to each other.

Steps in the Sighting Process

Initial Observation

• Observe different aspects like cast shadows, shading, glare marks, and relative sizes of objects.
• Focus on the differences in size to understand proportion.

Tools Required

• A pencil (used as a measuring tool).
• Fully extended arm: Ensure the elbow is locked to prevent changes in measurement.

Measurement Technique

• Step 1: Use the sharpened tip of the pencil to mark the widest part of an object (gourd).
  • Use thumb to mark the other end of the object.
• Step 2: Keep the thumb steady and compare the size to another object.
  • Calculate how many times the size of one object fits into another.

Sketching

• Start with preliminary sketches focusing on proportion rather than detail.
• Measure and compare each part of the objects to check for correct proportions.

Adding Detail

• Once proportions are correct, add detail such as:
  • Shading: Begin with dark areas and gradually add lighter shades.
  • Cast shadows: Helps anchor the object, creating a sense of weight and position.
  • Secondary shadows: Often multiple light sources create additional shadows.

Practice Exercise

• Try the sighting technique with the still life provided on the table.
• Focus on getting the correct proportions and adding basic details.

Conclusion

• Sighting helps in understanding and rendering correct proportions in drawing.
• Practice regularly to improve efficiency and accuracy in using this technique.
