I hope I'm not hijacking your thread, but I
just had an "ah-ha" moment about an hour ago with
wireless off-camera flash!

I didn't know who else to share it with, so I thought my friends here would best appreciate this.
I have a Canon 7D and a Canon 580EX external flash. I've always known that the Canon 7D can control an external flash wirelessly, but I never got around to trying it out.
Part of me was scared about the requirement for "line of sight", meaning the flash has to be able to "see" my camera in order to fire. So I resigned myself to the fact that I might have to shell out a lot of $$$$$ to buy wireless flash triggers, like those from PocketWizard, if I wanted to do wireless off-camera flash
without line-of-sight.
So I decided to finally try this out. Here's my very first picture using wireless, off-camera flash (you never forget your first

):
Yay! It works!
You'll notice that I swiveled the flash head so that the red sensor was pointing toward me so that it could "see" my camera. So the flash had a line-of-sight toward me & my camera.
What if I didn't have direct line-of-sight? I sort of hid the flash under a coffee table, and here's what I got:
WOW!

I'm so excited that I don't need
direct line-of-sight for this to work!
Then I started to make things even more challenging. I tried my best to "hide" the flash and see how much line-of-sight I
really need. I hid the flash in a grocery bag:
I hid the flash in the microwave:
I hid it in the dryer:
I hid it in the other room:
All I can say is WOW!!!

This totally opens up a whole new world for me! And to think I've had this capability in my camera & flash for about a year, and I was too reluctant & scared to try it. What was I thinking?!?!?!
At least this tells me that I don't have to spend $$$$$ buying PocketWizards (or any other wireless flash triggers)...at least not for a while. If anything, I might think about buying another flash so that I'll have TWO flashes to control!

Or maybe I'll buy an umbrella & a stand for the flash. Oh, the possibilities...
This feature isn't unique to the Canon 7D. If you've got the new Canon T3i or the Canon 60D, you can do this too. Apparently, the Nikon folks have been able to do this for years.
The only annoying thing about this is that I have to use the pop-up flash to control the other flash. The pop-up flash sends out a seizure-inducing burst of light, especially in very low-light situations...but I think that's for autofocus purposes. If there's enough light in the room for the camera to autofocus, then the pop-up flash doesn't do this as much.
Anyway, just wanted to share my enthusiasm. I'm so THRILLED with my new "ah-ha" moment!
