– Measuring in Perspective
It takes a lot of experience to develop an eye for scale, especially when trying to manage dimension over great distances. While using a grid can be helpful, it’s not the only way to control size when you’re drawing. Built into perspective are formal (mechanical) and informal (estimative) ways of measuring. This is where perspective really shines; many of the ideas are decidedly simple yet incredibly powerful. So much so, that they can even be used while sketching – no rulers, vanishing points, or cones of vision. The precise mechanical nature of most of perspective can wait.
