Trust me, the Canon 580EX II flash gun is not easy to comprehend. So many buttons, and some make no sense whatsoever.
In an attempt to understand what the user manual tries to explain with too many pictures and gobbledygook, these eight videos cover fairly well.
What you’ll love is how simple these are to follow, comprehend and implement.
After watching these, you can return to the user-manual that came with the flash-gun to work on the smaller details. After all, it is a really cool MASTER-flash to which the 430EX can be a SLAVE!
