Photo a Day
It turns out it means negative space--something that artists and photographers use to create a silhouette or draw attention to their image. Now I am certain that the words artist or photographer will never be used as a title beside my name but I interpret negative space as using a solid background to make your subject stand out--like the ocean water that is surrounding my grandson who is the focus of this photo. I just wanted to see his expression not the sand or sun or other things that were nearby.
I may be on the right track, I may be completely off but I like this photo using "negative space."
