How to see EXIF data from my flash

I had a problem with my flash at a wedding last night. It was total blowing out my scene. The flash was supposed to be in ETTL mode but when I pulled it out this morning to see if I could duplicate the problem it was in M mode (manual). If this was the case last night then problem solved.

Looking at EXIF in Lightroom provides little EXIF for the flash. It only tells me if it fired. Is there a way to see my EXIF including details of the flash modes and settings?

I'm pretty certain your flash went into TTL (not ETTL mode) because of a bad connection. ITs a pretty common thing, especially common if you use an OCF cord without a good shoe design.

I was using a 5D MarkIII with a 580EXII in its hot shoe. I would like to know if there is a way to see flash EXIF data, if there is such a thing.

Afaik, there is no way to find out the power settings of a flash in the exif data.

Regardless its probably still a connection failure. What you describe has happened to many of us here.

I just looked at the EXIF data in a file from a wedding last Saturday.
The file was shot raw with a 5DIII and a 600EX-RT on camera, as well as two off.

Use an EXIF tool that looks at an excruciating amount of the EXIF data, the only mention of Flash is that it was mounted and fired.

As to your problem, either it was a poor connection as mentioned, or you inadvertently tapped the button that changed it from ETTL to M.

I know its Monday morning QBing, but didn't you look at the back of your camera during the event?
I caught a mistake where I'd hit the button and changed the 600 from ETTL to M. Two bad frames, then 3 good ones of the bride and maid of honor. (I have to remember the lock position on the switch. )
