Shared this post with my upper level graphics students, although all of my classes would benefit from reading this! First hand account of how an illustrator's work was literally stolen and reproduced.
What could she have done differently?
"Positive space refers to places where visual information is, and negative space refers to where it isn't. Balancing a page by weight does not guarantee a balance in positive and negative space. In fact, other principles advocate limiting the amount of information on any one page, and so it is common—and often desirable—to end up with a design that contains more negative space than positive space. Balance can still be achieved if the positive elements are properly "grounded" (as by the vertical white bar to the left), and not freely floating in a sea of negative space."
Negative space may be most evident when the space around a subject, and not the subject itself, forms an interesting or artistically relevant shape, and such space is occasionally used to artistic effect as the "real" subject of an image. The use of negative space is a key element of artistic composition.
