The best thing about wide-angle camera lenses is the sense of extreme perspective they let you bring, creating really neat effects otherwise impossible to achieve. For example, take this nutcracker:
At 24mm focal length, he's a perfectly respectable fellow, with a nice scottish theme.
However, at 10mm, he's turned into a bellowing drunken scotsman, ready to punch you in the face!
Similarly, enjoy this cow skull:
How quaint! It gives the room a bit of the savor of the wild west.
But look closer... and he turns into a wild devil cow, chasing you through your scariest nightmares!
MooOOOOo!
