"When I'm ready to make a photograph, I think I quite obviously see in my minds eye something that is not literally there in the true meaning of the word. I'm interested in something which is built up from within, rather than just extracted from without" .......Ansel Adams

These words are very much true with liquid photography.

Liquid photography is an art where the Images are taken manually by dropping the water or any other liquid on a liquid surface & photographed at appropriate timing when droplets form extremely variant & unusual shapes. Soap films is another arena which creates very colorful abstracts when photographed in interference to light.
