Photographer Rod Evans took this 20 second long exposure with some steel wool (lit) and a 360 camera. He then took the raw image and gave it the ‘tiny planet’ effect. On reddit, where Evans shared the photo, he adds:

 

The camera I have is the Insta360 ONE. To do this shot I placed the camera on the ground about 2 metres away from me and set it to a 15 sec countdown timer which gave me time to find my position and have the steel wool burning and spinning by the time the camera shutter released. This is a 20 sec exposure. I took the image and distorted it in ‘Insta360 Studio’ to produce the tiny planet effect.
