This would allow people to start filenames with date-time so alphabetical order is same as capture time order, and would create unique filenames (without yet another field) and properly order bursts....
Presently, exif metadata includes subsecond field, but Lr filenaming template stops at full seconds. So for unique filenames, one would have to tack on some kind of sequence number or something as well.
So, as things stand, one can have:
but not (as I would prefer):
A side benefit is that filename indicates subseconds between shots in a burst, which is otherwise unavailable in Lightroom without a plugin. Although, I could argue for displaying that too in formatted metadata display, even if only upon mouse-over.
--------------- I would like to use Lightroom import dialog box for importing, instead of the plugin I use now, but it stops just shy of what I need/want still. - this is one of the things. However, if import actions were implemented, that would be enough.
