Long exposure zoom-outs.
Bored Panda offers the following instructions:
1. Use a tripod, or stabilize your camera on a flat surface.
2. Set your ISO setting as low as it will go.
3. Set your aperture to F10/F11.
4. Set your exposure time to 2 or more seconds. Then, when you snap the long-exposure photograph, zoom your lens all the way in our out to stretch out the lights you see.
Works on illuminated keyboards too…
