On camera flash...off camera...

It's been covered elsewhere at length, but in case you're just coming into the game here's the scoop:

If you are only using your on camera flash...well... on camera, take it off! Both Canon and Nikon flashes (yes I am mostly a Canon user, but I try to give equal time) have a built in ability to trigger other flashes at the same time, and certain Nikon camera bodies can trigger remote flashes using their built-in flash! Both companies also offer remote triggering units that are just that... they look a little like flashes but only fire barely visible IR flashes to trigger remote units.

The idea is to get your source of light off center to create more depth and feeling into your flash images. With thousands of hours a little practice you'll be wondering why you ever settled for a single attached flash.

NOW keep in mind, many of the things I will recommend to you here will cost you lots of money! You will find yourself with more flashes than relatives on Christmas... I can't control that, it's your own fault for becoming addicted in the first place! For more in depth reading on where to start with off-camera lighting.. go see my drug dealer hero: The Strobist
