TTL vs ETTL | Canon 580EXii / 430 EXii Speedlite DVD

http://www.canonspeedlitedvd.com - This is a short video which explains the concepts of TTL and ETTL flash metering systems. Flash photography can be extremely tricky, so I made this video in hopes it would help you learn what TTL and ETTL are and how they are different. Its just one of many lessons from my new DVD: Canon 580 EXII 430EXII Speedlite Crash Course. Over 3.5 hours of awesome lessons.
