"What is negative space? in art, is the space around and between the subject(s) of an image. Negative space may be most evident when the space around a subject, not the subject itself, forms an interesting or artistically relevant shape, and such space occasionally is used to artistic effect as the "real" subject of an image." I found this definition on the inter-webs without credit to the 'definer'.
With the word negative in the name, it sounds like a bad thing which is why I wanted a definition. Negative space is used a lot for quotes and memes, so the actual space that is not your subject could be blank space. See second image below.
Happy weekend everybody!!
