Mark Iuzzolino (04.26.09, 11:25 AM): Michael, I have the 430EX Speedlite. Will this new video be useful for working with my 430ex?

Dan (04.26.09, 4:52 AM): looks like you are pouring water into a glass!

michael andrew (04.25.09, 3:22 AM): :) Yes, the video from this will be cool- it will explain the concepts of flash metering systems in about 2 minutes.

cindy (04.24.09, 4:05 AM): it will be fun to see exactly what you are doing on the DVD. :)
