Newbies / XMP-dc: Subject

Last post by prestonmcafee - Today at 12:33:22 PM

I'm trying to erase a field XMP-dc: Subject.  The relevant section from the exiftool list:

---- XMP-dc ----
Subject                         : Toni, Zoe Phelps, Sophie
Title                           :
Description                     :

I'm running exiftool using python and the relevant piece is

keywords = ""
subject = ""
files = [docroot+'2005/Apr/66.jpg']
with exiftool.ExifToolHelper() as et:
    # Execute the exiftool
    et.execute(
        f'-EXIF:XPKeywords={keywords}',
        f'-XMP-dc:Subject=subject',
        f'-overwrite_original',
        *files
    )

The code eliminates XPKeywords successfully on jpgs that have that entry, which makes me think the problem is my target of XMP-dc:Subject, but I'm a newbie with exiftool.  I attach the original image and the exiftool output.  Once I learn how to do this, I will apply to 36K images as well as know more about exiftool.

The "exiftool" Application / Re: Add timezone to MOV video ...

Last post by StarGeek - Today at 10:19:55 AM

For a while I was confused to read that because many eastern countries like Japan do not use DST. But then it crossed my mind that you refer to the U.S. east. Doh!

Heh, sorry.  You used -05:00 in your example, so I was trying to indicate that time zone without reference to Standard or Daylight time.

[rant]I wish DST was no longer used anywhere.

I'm with you.

TimeZone is supposed to contain the base time zone without regards to any possible Daylight Savings time change. For example, for Eastern time zone, it should always remain set at -05:00.  The DaylightSavings is the indicator for when the camera is supposed to add an hour or not.

For a while I was confused to read that because many eastern countries like Japan do not use DST. But then it crossed my mind that you refer to the U.S. east. Doh!

[rant]I wish DST was no longer used anywhere. A few  years ago Finland proposed that EU should stop using DST and it was favorably greeted. But then it was buried in EU bureaucrazy and sadly it also locally spurred heated debates whether we should then stick to standard "winter" time or "summer" time  [/rant]

writing directly to Time:All is a bad idea because it writes so many tags. Using it with the -wm w is about the only reasonable exception.

I try to keep that in mind although sometimes -wm w -Time:All makes the command much shorter

It appears that "USMLensElectronicMF        : Unknown (3)" is "[Disable in AF mode] Disable in AF mode

Manual focus adjustment is disabled when the lens's focus mode switch is set to AF."

This might vary by type of lens attached.

The "exiftool" Application / Re: jpg Exif CreateDate as pre...

Last post by jacky - Today at 04:37:45 AM

I just found a solution:
https://exiftool.org/faq.html#Q27
which was mentioned in this post:
https://stackoverflow.com/a/72407154/17058700

Now I'm using the doubled percents in the date expression

Code Select Expand

exiftool "-FileName<FileModifyDate" "-FileName<CreateDate" -d "%%Y-%%m-%%d_%%%%f.%%%%e" .in a batch file which generates the filename "2017-10-03_ram_1.jpg" which is exactly what I wanted.

So far I'm contented

The "exiftool" Application / jpg Exif CreateDate as prefix ...

Last post by jacky - Today at 02:34:39 AM

Hi,

when I print the data of my ram_1.jpg - file I got all the values, see attached log.txt.
The date is printed as (german layout):

Code Select Expand

Create Date                     : 2017:10:03 11:27:27.069474
Date/Time Original              : 2017:10:03 11:27:27.069474
Modify Date                     : 2017:10:03 11:27:27.069474
I'm searching for hours now in this forum and in Google how to prefix the Exif-date into the filename and it still doesn't work.

E.g. trying

Code Select Expand

exiftool -d "%Y%m%d-%H%M%%-03.c.%%e" "-filename<CreateDate" .results in

Code Select Expand

Warning: [minor] Unrecognized MakerNotes - ./ram_1.jpg
    1 directories scanned
    1 image files updatedand creates a file "mHe" (without extension).

Or

Code Select Expand

exiftool -fileOrder DateTimeOriginal -recurse -extension jpg -extension jpeg -ignoreMinorErrors "-FileName<CreateDate" -d "%Y-%m-%d%%-.3nc.%%e" .results in

Code Select Expand

Warning: Error rebuilding maker notes (may be corrupt) - ./ram_1.jpg
    1 directories scanned
    1 image files updatedand creates a file "m-e" without extension.

Trying to set the colons in our german date FMT string

Code Select Expand

exiftool -d "%Y:%m:%d %H:%M%g" "-filename<CreateDate" .reports

Code Select Expand

Warning: New file name not allowed in Windows (contains ':') - ./ram_1.jpg
    1 directories scanned
    0 image files updated
    1 files weren't updated due to errors
Could you help me how to manage this date prefix into the jpg filename?

I've got so many images and this would help me a lot. 

Thanks in advance.

Newbies / Re: Help wih renaming files

Last post by MnM - Today at 01:24:01 AM

I have tried to make this work but I am encountering issues.

Below are the commands that I using to rename and move files:

Prepare files for correct suffix 001, 002 etc

Code Select Expand

exiftool "-FileName<Datetimeoriginal" -d "%Y-%m-%%.3nc.%%e" -fileorder datetimeoriginal -ext jpg -r Z:/Uploads/PhotosAndVideos/Photos

Rename and move to correct folders

Code Select Expand

exiftool "-FileName<Datetimeoriginal" -d "Z:/Photos/%Y/%m-%b-%Y/%d-%m-%Y-%H-%M-%S-%%-3f.%%e" -ext jpg Z:/Uploads/PhotosAndVideos/Photos
Next I am trying to run a second pass on the folders created above (so i can rename the suffixes correctly) but I have no idea how to make it scan only the folders (year/months) that were created above.
I need help with this part please.

Thank you - I guess is not too bad and I can run a second pass to get the numbering correct.
