Question 1

Discuss how to maintain correct proportions when freehand sketching.

Accepted Answer

Freehand sketching requires judgment about how the sizes of different features are to be correctly proportioned. With practice, the eye can adequately create and maintain proportion without the use of superfluous, time-consuming devices. Usually, an approximation by eye is adequate. If a grid paper is used, each block generally represents a definite measurement. Still more precise sketches may be made by the use of measuring instruments.
