P: Support sub-second (milliseconds) field in file naming templates.

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:

YYYY-MM-DD_HH-MM-SS_{seq-num}_{photog/camera...}

but not (as I would prefer):

YYYY-MM-DD_HH-MM-SS-MS_{photog/camera...}

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.

Hey All! I've updated the announcement, the status, and added the ticket to track this feature request further. 

Thanks!

Sameer K pinned a reply that I may not understand. Yes, I see that Lightroom Classic v15.0 supports millisecond time, but I do not see the support in the file rename function [F2]. I can create a date format as shown below, but I cannot select anything shorter than seconds. It would be very helpful if we could select the number of decimal places of the seconds to be included in the filename.

@Sameer K Also on the latest version and not seeing in option for milliseconds in bulk rename templates. It's been something have wanted for so long for auto importing renaming but I like the other commentors are not seeing what you are seeing. Can you provide a screenshot of it showing in the bulk rename template builder or which variables you are using if its not part of the UI?

@Sameer K, like @fotolandowski, I don't see any file-naming tokens that would output capture-time milliseconds.

 

Here are all the naming tokens in TranslatedStrings.txt (no mention of milliseconds):

"$$$/AgNaming/Token/DateMenuTitle/Day=Day"
"$$$/AgNaming/Token/DateMenuTitle/Month=Month"
"$$$/AgNaming/Token/DateMenuTitle/Time=Time"

hi @Sameer K

 

that's a great news (pity that it took 14 years?)... but... i have the latest version i believe.. but no miliseconds in renaming templates still...

Is it hidden somewhere?

Thanks!

Hello everyone, 

The MAX release for Adobe Photography products includes an update addressing the requested feature that addresses part of this feature request in selected fields. The team is working on the rest of it. 

 

If the update isn’t visible in your Creative Cloud app, refresh it using [Ctrl/Cmd] + [Alt/Opt] + [R].
Please note: It may take up to 24 hours for the update to appear.


Thank you for your continued patience.

@johnrellis thank you! Well, I never found that in all these years - shame we have to parse an ISO string instead of having something formatted to look that, but this will do the job.

@stephen.trainor: "It's a PITA to have to switch out to other applications to view this field"

 

LR displays the capture time's fractional seconds in the IPTC > Date Created field:

 

 

Sorting Library Grid view by capture time will recognize the fractional seconds.

Here I am a few days after the eclipse trying to get precise relative timing for my many photos, taken at 20fps, in order to analyse them against high precision eclipse predictions. It would be very helpful indeed to have access to EXIF's "Sub-Second Time Digitized" within Lightroom, both in the Library Metadata inspector and for file naming purposes. It's a PITA to have to switch out to other applications to view this field - please consider adding it. I'm sure there are many, many other use cases where this data is important.

I also would like to encourage Adobe to include this important feature, and to know when this will be implemented. I find it useful to change the name of the image file to something meaningful and I include the date and time to avoid duplicate file names. If I shoot a burst at 10 frames/second I might get 10 different image files within the same second, so subsecond time is important to separate the file names. I used to use Downloader Pro to change the file names and that program handles subsecond times (it appears Nikon records subsecond times to 0.01 second in .NEF files). Alas, I have switched from Windows to Mac and Apple does not support Downloader Pro. I wrote a python script to do the job but it would be SO MUCH EASIER if it could be done with the Lightroom import.
