How to use external Flash unit

[wolvie77]

Hi! All. i'm thinking of buying an external flash unit for my Nikon D5000. i notice that many flash units have markings & switches on them. can't make sense out of them. anyone can brief me on how an external flash unit is used together with a DSLR?

Read the flash instruction manual.

Read the camera manual. Certain settings don't need to be done at the flash but rather on the camera. Hint: check your camera menu for flash options.
