How to use Canon Speedlites

Quite a while ago, flashes were quite simple to master, of course with limited options.  One just slid the flash onto his/fer hotshoe and took the photo.
With new technology and smarter flashes these days are long gone.  Most Speedlites have a variety of settings, LCD screens, lengthy menus, and are able to communicate with other Speedlites too.
We found a very interesting seminar, jam packed with information on how to use your Speedlite.
It's two hours long, but very worth watching!

Enjoy :-)
