This chapter aims to provide more information about getting your Speedlites set up for on-camera use and off-camera wireless operation. I discuss some finer details of the Speedlite's features and capabilities, briefly explain the optional flash exposure modes, and offer tables that list all the Custom Functions that are available with the 580EX II and 430EX II and suggestions when you might use them.

Creative lighting and intuitive use of your gear are your goals, so let's get started!
