Metadata / Need a favor from a Exiftool g...
Last post by cdubea - July 07, 2025, 11:17:07 AMSo,
In the preceding months, I've transitioned my image ingest duties from LightRoom v6.14 on a Windows box to Rapid Photo Downloader on a Linux box.
RPD works well, but one of the things it doesn't do is any kind of IPTC metadata handling.
Typically, I will ingress to a folder thusly:
/photos/2025/0617-Wyatt
And rename the photos in the folder thusly:
20250617-Wyatt.001.jpg
I use Capture One for my post-processing, but unfortunately metadata handling in C1 is challenging. It's possible, but it's a cluge at best.
Would some kind soul please advise an ExifTool command to set the descriptor of the file (in this case Wyatt) to be the IPTC Caption for a folder full of images? Obviously, the descriptor would be different for different folders.
Thank you.

Last post by Phil Harvey - July 06, 2025, 09:45:08 PMYou should be looking at the return value of WriteInfo to see if everything went OK. Also to debug this you could do $exifTool->Options(Verbose => 2); to see what it is doing when writing.

Last post by Jhe - July 06, 2025, 09:33:37 PMThank you for the excellent performance of ExifTool.
I have some .MOV files from a Sigma fp and Sigma fp L, which should be in the same format as the Sigma BF, but they are not being parsed correctly. The metadata such as maker, model, and focal length cannot be read.
Could you please take a look at the following MOV video shot with the Sigma fp?

Last post by StarGeek - July 06, 2025, 07:19:37 PMQuote from: Kloomnik on July 06, 2025, 05:18:24 PMI want to concatenate several existing EXIF fields (e.g., Caption, City, State, Country) into that single field.
Minor nitpick. None of those are EXIF tags. They are either XMP tags or IPTC tags. Or both in one case. Use the command in FAQ #3 to see the groups they belong to. That command will also give you the actual names of the tags, which can be different from what other programs list. For example, you say "Caption", but if you actually write to the Caption tag, you are writing to a tag that will only work with the ACDSee image management program. What you probably want to write it is either Caption-Abstract (part of the older IPTC standard) or Description (the newer, modern XMP standard).
This example from the Copying Examples section of the docs shows you how to combine simple text and tag values when copying to another tag.
As the example shows, you simply add a dollar sign to the front of the tag name. If the tag name isn't followed by a space, you add braces as with ShutterSpeed in that example.

The "exiftool" Application / Concatenating several exif fie...
Last post by Kloomnik - July 06, 2025, 05:18:24 PMHi Exiftool'ers
I intend to import several thousand scanned images into Mac Photos. Practically, its only "free" field of information is Caption, and I want to concatenate several existing EXIF fields (e.g., Caption, City, State, Country) into that single field.
I succeeded in rewriting one EXIF field with another, but not in concatenating several fields.
Because of the number of photos involved, this has to be batched. That is, solving the problem for each image separately in a GUI interface is not feasible.
Hence, can I do it with command-line ExifTool?
Any help with be appreciated.
