"Abstract art uses a visual language of shape, form, color and line to create a composition which may exist with a degree of independence from visual references in the world. Artwork which takes liberties, altering for instance color and form in ways that are conspicuous, can be said to be partially abstract. Total abstraction bears no trace of any reference to anything recognizable." (Wikipedia).
“Even the most boring picture will get an injection of visual pleasure, when you add special effects to it. And why not? If it makes you stare at the picture, it has done its job well”. (Palle Schultz).
Over the last years I have made more and more (partially) abstract pictures. It is fun and it is difficult.
