Here's another instance of me using the daylight leaking in my studio to light paint.
The first photo is a dual camera rotation with the camera oriented a few degrees off the axis of rotation, twice. The gaps in the circles are caused by me rotating the camera with hiccups. fast, slow, fast, slow.
The second one is a single rotation with subtle rainbow effects from diffraction grating.
