Canon Image Challenge 146 : Negative Space

What is Negative Space in reference to Photography?

I could give examples, as from a Google Search:
http://www.google.com/search?q=negative+space+photography&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUKEwj67d23qZ7JAhVHKCYKHRxBCXcQsAQIHQ&biw=1920&bih=920

Or a really bright essay on the Topic;
http://www.photographymad.com/pages/view/understanding-and-using-negative-space-in-photography

Or, from the 2004 exploration of this topic:
https://pbase.com/cslr_challenge/cslr35_eligible
https://pbase.com/cslr_challenge/cslr35_exhibition

I think that you find the field much more open that you might initially imagine...but to your capable hands I surrender this idea for you to make your own.

Please join us and have fun!

Best Wishes, Traveller
