How we define the abstract photography? I think the photograph that represents author’s mind in ordinary scenes is an abstract photograph. It may be the out-focused picture, or the mixture of parallel lines or shape. The blurred effect is one of the most common elements that abstract photographers use since it’s easy to demonstrate their mind or the thoughts they have in the photography.  As a result, my own definition of abstract photography is the one that makes people to feel about the photographer’s thinking.
