q. regarding flash info in EXIF

Does anyone know just what information is passed on from e.g. the 430ex flash to an EOS camera (in my case a 5d). Specifically, I am curious if information regarding tilt and rotation settings of the flash are recorded. I doubt it is but I'd find it terribly useful if it is.

thanks!

I really don't think that tilt/rotate information is something that EXIF pulls.

No, that data isn't captured in EXIF.

I'd be happy if the flash power from my 580EXII got recorded by my 5D. I see fields for it but they're blank.

IIRC the only information that is recorded in the EXIF is that flash was fired or otherwise, no details at all

+1...This would be extremely helpful to folks who are just learning about flash/E-TTL.

It's the same as not recording ISO/shutter speed/f-stop for the ambient exposure.

I believe the 580EXII will tell the camera of the color temperature the flash generated. The color temperature of the flash varies as the flash power level varies. So to get a correct color temperature for the white balance, the flash has to tell the camera the color temperature for the flash power it used.

As promising as this sounds, the color temperature vs power level curve for the flash camera is bell shaped IIRC. So you can't say that a flash instructed color temperature of X translated into a power level of Y. So it doesn't seem that you can reliably determine flash power used from the flash color temperature value.

Using KUSO Exif viewer i'm getting
FlashFires
FEC
FlashOuput (given in %)
FlashSyncSpeed
FlashBatteryLevel (dubious!)

amongst others. Can't vouch for the accuracy, though.

Thanks for the info guys.
