Campfire Blackhole

How this was taken:

 

Set my Nikon 4600 to [scene] fireworks mode. This sets a 4 second exposure.

I pressed the shutter release while holding my gloved hand in front of the shutter, then I counted to three and gently spun the camera into the air and caught it again just as the shutter clicked closed. Nothing special. This came out of the camera exactly like you see it here.
