Intentional Camera Movement (ICM) involves moving a camera during exposure to achieve a creative or artistic effect. This causes the pixels to move across the recording medium and create different effects such as stripes, textures and layers in the resulting image. The central idea of ICM photography is that movement serves as the primary compositional element. Strict technical or definitional arguments remain vague in this form of photography, which has a long history and is associated with many other forms of photography, such as impressionism, and often blurs genres and styles.
