I have a whole bunch of home brewed scripts to take care of things such as sorting, renaming, HDR assembly and so on and so forth. These work from the EXIF tags, e.g.
Exif.CanonFi.BracketMode SShort 1 Off Exif.CanonFi.BracketValue SShort 1 0 Exif.CanonFi.BracketShotNumber SShort 1 0
which help greatly to keep large numbers of pictures manageable.
Unfortunately ML does not seem to store any of its metadata in EXIF tags, and instead creates the enfuse scripts, except if one shoots in RAW (which I do) and which have other limits (e.g. for free-hand HDR I use hugin tools for alignment first).
Would it be possible to make use of the EXIF tools (where available), store ML metadata/settings used to an Xmp.ML. range of metadata to preserve the settings in the images, or at the very least provide some form of Xmp.ML = true setting, so one knows whether this image results from ML and can make some educated guesses in trying to interpret the rest?
