Negative Space

The space around and between an image 
i found negative space in my drawings by seeing how i filled in the spaces between to form an image. 
It helps an artist see an image because it shows the an image from the spaces between and how the image form it's artistic shape.
For me in a way it does because it let me see another side of a drawling, but when it comes to drawling negative space that's when it confuse me.
