Messing around with Monochrome!

I've had my Canon EOS 550D (Lamagoo) for 1 whole year this Christmas! (Happy Birthday Lamagoo!) And I still don't know everything about it, so the other night I decided to muck around a bit with the settings.
I found the "auto" ISO setting is WONDERFUL! If it wasn't for my distaste of "auto" settings I would have found this out a long time ago!!
Anyway, I discovered the Monochrome setting in my camera travels, I've seen it before but never really used it.
Here are some photos I caught using good ol' Monochrome!
Hope you enjoy!

(P.S - do you have any hints or tips for using Canon's?)
