Flash power in metadata?

Hi all,
where I can find out in lightroom settings on how much power the flash was fired? I am not looking for compensation but mostly on the power like 1/8, 1/32 and so on.
Regards,
Alex

i don’t believe there is an EXIF setting for that.

Also, working backwards, your flash would have to report it, your camera would have to accept it an record it in the metadata.

Also, working backwards, your flash would have to report it, your camera would have to accept it an record it in the metadata.

And if recorded in metadata, it would be a sub field of the Makers Notes field. Generally, Adobe does not parse the Makers notes field into subfields as each manufacturer and camera model contain different subfields.

it seems indeed like that,....
I wanted to see with how much power my flash typically fires

Upload a sample raw taken with the flash to Dropbox, Google Drive, or similar, and I'll see if it's recorded in the proprietary Makernotes metadata section and, if it is, suggest a plugin solution that will let you see it.

Here are all the manufacturer-specific flash fields:

If this has what you're looking for, you can use the Metadata Viewer plugin to view them within LR (and any other field contained in the metadata).
