You can scale better

All drawing from a visible subject is comparative drawing.
That's true whether you're in Sight-Size or not.
The difference depends upon scale.
When you draw at a different size than you see your source you have to scale your drawing. That is variously known as comparative drawing, proportional drawing, and Comparative Measurement.
When you're not in Sight-Size, you are drawing using Comparative Measurement.
It helps to have a trained comparative eye.
And the best way to develop a comparative eye
is by deliberately practicing discrete skills that focus
on scaling your source image.
A Comparative Eye
contains over two-dozen progressive exercises suitable for everyone who wants to improve their visual accuracy when using Comparative Measurement.
The exercises in
A Comparative Eye help you practice
scaled reduction and enlargement.
Each exercise comes with keys, that show you whether or not you have accurately scaled the images.
