Turns out that “Wiggling the Camera” is not the official term for the technique I used to make these photos. I learned that it’s actually called “Intentional Camera Movement”, or “ICM” for short. It sounds a little bland and stuffy, in my humble opinion, though I suppose it does win points for accuracy.
I Intentionally Moved the Camera during a long-ish exposure time (shutter speed of 1/4 second) to achieve an abstract, painterly look here.
Whatever it’s called, I like it.
