ICM photography
Something I have got into recently is ICM photography. ICM stands for Intentional Camera Movement and as defined in Wikipedia "... a camera is moved during the exposure for a creative or artistic effect. This causes the image points to move across the recording medium, producing an apparent streaking in the resulting image." Sometimes several ICM photos are combined together in-camera or in post processing and the final picture may take an abstract, impressionistic look.
I have talked about the ICM technique in my blog here and here.
Below is a selection of my ICM images.
