I have been hearing about ICM in a few photography groups I am in and couldn’t figure out what they meant…so I put my trust in google and looked it up. ICM is Intentional Camera Movement. I have tried this method before, but didn’t realize it had a name. ICM is when you intentionally move your camera while the shutter is open for a creative or artistic effect. You can move your camera or zoom in or out on your lens for different effects. You need to use a long exposure, so you will need a ND filter or take the photo when the sun is not bright. Ensure your ISO is as low as it will go and your aperture stopped down as low as well (higher f stop number).
These are a few photo I took of a tree in my backyard.
