Delete image-description "OLYMPUS DIGITAL CAMERA" in all images on a device

[ernst.w]

Hi Phil!

This was across ALL of my Olympus samples... JPG, ORF, AVI, MTS, MOV, MP4, etc.  Some tags will only exist in some of these formats.

I know.

I have checked an ORF-original where the Image Description field is shown in some software products (Capture One Pro as an example). But the field is not listed by exiftool.

D:\___Install\_TOOLS\_GRAFIK\EXIFTool\exiftool "H:\__EXIFTEST\ORF-Test 2" -filename

Sorry Phil,

there must be another additional mistake. See screenshot. (Maybe I am too tired today to see my fault.)

[Phil Harvey]

Great.  ExifTool is seeing the files now.

I meant to use the command I gave exactly, not replace -filename with a file name.  Other than that, it worked fine.  This was only a test command to print the names of processed files.

So the other commands should now work if you drop the trailing backslash.

Hi Phil,

thanks for answer and sorry about my delay but I was out this weekend. Today there are workmen in the house. I will try to verify tomorrow. I will come back when finished.

Hi Phil,

okay. Now I have run a test. Seemed to do something. But there are a lot of new questions:

1) The attached screenshot shows 845 files "done", okay. 224 files failed condition, okay - maybe there are not only 32 xmp-files but NEFs to which do not match condition of "OLYMPUS..." BUT where is the rest? There are 1.560 files in the directories.

2) to check if the image-description was changed (deleted) I tried to use exiftool again. It shows me a lot of EXIF datas but image-description is part of the ITPC datas and not shown. Is this the point why it didn't work (as Capture One shows to me)?

ImageDescription is EXIF metadata, not IPTC.  Caption-Abstract would be the IPTC (Legacy) equivalent and Description would be the XMP (IPTC Core) equivalent.

[ernst.w]

Okay. Let's take this as a fact.

But why does exiftool not show the image-description? Not even as an empty field?
And why does Capture One list image-description as an IPTC content?

Anyway, my problem seems not to be solved.

[Phil Harvey]

ExifTool may have different descriptions for the information than other software (see FAQ 3).

The newer IPTC Core specification uses XMP format.  ExifTool calls this XMP, but other software may call this IPTC.  ExifTool only calls the older IPTC IIM format "IPTC".

Hi Phil,

some irritations, sorry. It seems as if it had worked. Lightroom shows the result I wanted. As I use the German version the field is called "Bildunterschrift" not "Bildbeschreibung". And there it looks like as if it had worked.

I have to check out a little bit mor but have no time free today until weekend. I will come back then - I hope with a great "Hurrah!"

Hi Phil,

I will go live today.

All working fine - except the differences in counting what has be done and what not. This I could not really verify. Maybe there remain some images undone (I could not find an example really, only counting differences as mantioned above).

Thanks a lot for help. I wouldn't have got this fixed alone. Thank you, I appreciate!
