This effect is created with a controlled zoom burst effect, rotating the camera while holding the lens zoom ring. Effectively swinging rotating the camera as the lens zooms around a single axis. This is best achieved hand held...unless you have a fancy rotating lens tripod collar. This iamge below was shot hand held with a EF 16-35mm with a 1/6th second exposure. This lens is quite old and loose....if you have a newer lens then you might need a longer shutter speed.
This is a tripodded ICM. I used a controlled drop with a video fluide head to create a controlled vertical motion. It's far less random than trying this hand held.
I also left the lens image stabiliser on because it adds subtle wavy lines, enhancing the abstract nature of the image. This was shot at the wide end of a EF 70-200/2.8 LIS II with a hald second exposure.
I'm assuming this thread also covers simulated intention camera movement, where the camera is still bit the zoom lens elements are moved during a long exposure. Here the lens is internally moved?
This image is using the zoom burst technique, where the camera is tripodded but the lens is zoomed in or out during the long exposure. The movement is intentional, the camera is stationary, but the lens (attached to the camera is internally moved. Some call this technique a "zoom burst", some call it "ICM", some call it "Simulated ICM". EF 16-35mm at 1/3 second shutter speed.
The level of abstraction can be controlled by the amount of zoom chosen:
Here's some ICM abstracted Lupins. I tend to find that the ICM abstraction works best where there's part (or all) of the image slight out of focus.
It seems to add to the "What is it?" narrative.
My attempt using "zoom burst". It is the wagon wheel in our back yard during the snow fall yesterday. I thought the zoom looked better than side to side or up and down.
