Try this simple tip with your Fisheye camera and see things like a bird does - Given that he got transmuted with a Fishy eye!
Here’s one to try with your oh-so-quirky Fisheye or Fisheye 2 cameras (probably one with a Submarine, if you’re planning to do this near the water). First, look for a ledge or higher ground in your shooting area where the subject stands below your field-of-view. After doing such, easily point your camera down and shoot!
By doing this simple (yet pretty useful) technique, bodies are distorted, faces get bloated, backgrounds extended into a mind-blowing Fisheye exposition! Enjoy!
