Atmospheric Perspective

This piece of art is done called The Passage is done by an artist by the name of Natasha Lotona. This particular piece of hers is done with charcoal and shows great depth of atmospheric perspective. The fogginess of the trees as they go back into the background really gives the illusion that the drawing goes beyond the paper. In this case there is also fogginess towards the foreground of the picture which gives the idea that the scene goes  further forward as well as backwards.
