Title: Tag result only if requested individually?
Post by: handvprice on October 05, 2021, 10:31:25 AM
Windows 10. On a jpg from an iphone, if I use

"exiftool -s -a -u -G -File:JPEGQualityEstimate img.jpg"

it outputs the quality estimate of 95. If I use the same command without specifying the quality estimate tag, i.e.,

"exiftool -s -a -u -G img.jpg"

it doesn't show the quality estimate in the output. Is there something I'm missing? TY.

If you check the note on that tag's entry on the Extra Tags page (https://exiftool.org/TagNames/Extra.html), you'll see it says

      For performance reasons, this tag is generated only if specifically requested or the RequestAll API option is set to 3 or higher)

TY! That's the last piece of the puzzle to make exiftool work well in Directory Opus with all the desirable tags.
