What is the best way to adjust time for photos
Hello,
I get photos in subfolders "Person1", "Person2", with Exif Data. Unfortunately, I've to adjust the Exif time DateTaken depending on the persons, because the different photographers had not synchronised their times.
And I want at the end that each filename begins with the adjusted DateTaken as "AAAAMMDD_hhmmss_..."
My first idea was to insert at the beginning of the file name the DateTaken and the folder name : "AAAAMMDD_hhmmss_(Person1)_..." and then to apply some time adjustement depending on this filename. But I've not found in the standard Aren methods a way to adjust time when this time is written in the filename.
So For the time being, Id used 2 methods :
- use Javascript in Aren, it works but I'm not an expert
- add in Aren the Exif DateTaken to the file names, then copy the table in Excel in which I can calculate the new dates et the use the list method in Aren ; this is easier for me but I use two tools
Is there any other way ? It will be fine if there was a method which could directly extract the time info from the filename, add a timegap and reinsert the adjusted time !
thank you for your suggestions

Hello!
What you want sounds mostly doable in Aren. But the details are still a bit unclear to me.
Are you changing the DateTaken value?
How are you calculating the new DateTaken from the original files?
I don't *think* that Aren actually writes any exif data itself, but it does include ExifTool, which does write exif data++.
You can write a batch that calls Aren and/or ExifTool as necessary.
Give us concrete, *exact* examples if you want help with that. List: old filename, desired new filename, old date(s), desired news date(s), any desired changes of exif data.
Also, what OS and version of Aren?
~~~~~~
As for strategy, I typically use the tried and true methods of "general to specific", and "Most important first".
So that would be a filename of (Person), (Subject/Event/etc), DateTaken -- in that order. But whatever works for you and Aren kicks butt at renaming such schemes if you ever desire. ;)

Randy

Hi Villard,
I'd try to find a built-in tag, in the latest versions of ARen, since they can be time-adjusted with modifiers.
DateTime tags:
