Proportion and construction lines are the foundation of a good drawing. Learning to see height vs width vs length is an acquired skill using relatively simple techniques and tools.
Step 1: The Right Size
"All the visible world is only light on form" Andrew Loomis
We see outlines and immediately interpret the object as believable and existing in space. The boundary tells us almost everything we need to understand the artist's vision.
"How you draw is a reflection of how you feel about the world. You're not capturing it, you're interpreting it."
Step 3 : The Right Shape
"practice without knowledge is like a sailor who gets into a ship without rudder or compass...Perspective is the guide and gateway and without this nothing can be done well in the matter of drawing" Leonardo da Vinci
Composition and perspective create a sense of space. Our page becomes a window to look through rather than a flat surface. Knowledge of how the eye sees frees the artist to explore and experiment.
"An artist must have his measuring tools not in the hand, but in the eye". Michelangelo
"If I try to articulate every little detail, it would be like missing the forest for the trees, so it's just about getting the outline of the forest" Jeff Koons
Step 4 : Lights On
Step 2 : The Right Place
Values, light to dark shades of grey for drawings, complete the story the artist wants to tell. Through delicate rendering of light on form the drawing comes to life.
" It is only by drawing often...that one fine day you discover, to your surprise, that you have rendered something in its true character."
