CDLC Presents: Using a Speedlite's E-TTL Automatic Flash for Portraits

From the Canon Digital Learning Center:

"Ever since the Speedlite 600EX-RT was introduced a couple of years ago, my [author Eric Stoner's] life as a portrait artist changed forever. Don’t get me wrong, I loved my Speedlite 580EXII! But, the amount of additional control and reliability that the Speedlite 600EX-RT offers is, in a word, superior!

'Speedliting,' for many people, can be a scary proposition especially using E-TTL Automatic flash. One reason, and it’s a good one, is that you never really know how much power the flash is outputting. Does one really NEED to know that information? I’m sure for some of you that the answer is 'yes' and I understand it, but I’m a results kind of guy! I know that these Speedlites work very well and I trust them!"
