Positive and negative shapes. My Zentangle hummingbird. This is an example for my students' project. This can be use for several concepts: positive / negative space, reflection, line and shape, etc. I did this project with my grade students.
I like the use of negative space in this image to best convey the idea behind it. Not to mention it makes the text look interesting. <<Negative space in graphic design is a whole other art form all it's own>>
negative space: Shape and abstraction: This image uses negative space perfectly - depending how you interperet it, the negative space can either be the sky because it is less dominant, or the buildings, because they are darker and catch your eye less.
This book cover shows excellent figure ground/negative space. The contours formed by the position of the fox serve as the shape of a boy, I'm assuming "Peter." This empty space also creates a wonderful focal point for the book title to nestle into.
