@eclectech depending on what you have and what the software can do with the output, they are vaguely like an adjustable fisheye lens that you can move after the shot. some, also after the video too. get it in as odd a place possible for best/most interesting results. go close, go low, go high, go inside*
*not living things. dear Bod no, not living things. never let a small child chew on one, even if waterproof. *shudders*
@evilstevie Hahaha! The mind boggles :)
I have just been playing around with the whole post-shoot-adjustable-fisheye-lens bit. It is sooooooo much fun! Only really played with stills so far but apparently will be able to do it with video too (and it hooks in with Premier Pro which I was forced to work out how to use for a work project, so hope to be able to build on that for fun stuff)!
