A Fish Called Wander
Rokinon 8mm fisheye lens, intended for use on crop sensor DSLR cameras.
I shaved off the original built-in lens hood to allow this wider field of view.
The camera was a Nikon D600, placed on top of a 4' tall tree stump, facing straight up at zenith.
Exposure time was 30 seconds at f/5.6 and ISO400
