Videos demonstrating good contrast

So, when I was looking for a video or an animation, I thought about looking up some kind of shadow theatre video. The use of only white and black, the light and the shadow against the light, creates a very good contrast and a bright picture. This is the first video:

As I was looking for more videos, I came across videos by a dance theater called Pilobolus. They use shadows of their bodies to create images on a light screen. Probably some of you know about them, but I have never heard of or seen them before. They are pretty amazing!

This is a video from their performance at Late Night show with Conan O'Brien (i love the dog in the video it just made me smile :)

here's a Hyundai commercial. this is an incredible way of art!

and another one from them:

Examples of strong contrast and positive/negative space relationship

First one is an English/American artist Clare Leighton. She is mostly famous for her wood engravings. She has illustrated many books. Also, a lot of her works picture everyday life of factory workers, fishers, farmers, good old people who work on the land. I discovered her amazing work at Dixon Gallery (by the way her exhibition is still on: http://www.gomemphis.com/news/2010/jul/09/painstaking-images-on-wood/, go see it!!)

Her prints are very intricate and sophisticated. I can't imagine how much time and skill it would take! Also, the whole process of wood engraving makes the artist to think of positive and negative, black and whites in a kinda backwards way, because places you don't touch will remain black, the places that you cut most will be the whitest. It's the same principle as in charcoal erasure technique.

Next artist is Felix Vallotton, a Swiss painter and printmaker. He was an important figure in the development of the modern woodcut. His reductive woodcuts have really sharp blacks and whites, and are really good examples of contrast and dynamic between positive and negative space.

I really like this one's composition and the idea:

The last guy is a contemporary photographer Rodney Smith ( http://www.rodneysmith.com/)

I really like his compositions and subjects of his photos. He works a lot in black and white photography. Here are some of his photos:

This one's composition is simply brilliant and it looks almost surreal, interesting positive and negative shapes and lines, really good contrast:
