comparing exif - amazon photos problems

[lorife]

Hello,

I have 2 images which backup on Amazon photo.
One of them gets the date-time correctly, while the other arrive on Amazon Photo with "no datetime".
I used exiftool to compare the exif data but I don't see any problems.
Could you help me understand what's wrong?
the correct one is 1238.jpg while the wrong one is 1229.jpg

thank you

I don't know why Amazon treats them differently but they are different file formats and one has been modified by Picasa and the other one hasn't.

hello,
thank you for answering.
Where do you see they are different file format? aren't they both jpg?

It seems that this command:

-EXIF:all= -tagsfromfile @ -EXIF:all -unsafe

solved the problem.

But why? what's changed?
Here is the new exif

EDIT:

at this point, how is best to proceed?
Can I run this command with all my pictures? Or is there a way to update only the pictures with the problem?
Also, how to I run this command in all my pictures, is it like this?

exiftool.exe -EXIF:all= -tagsfromfile @ -EXIF:all -unsafe -r C:\Temp\aaa\

Can you share a sample image that amazon doesn't read properly?

Has that file been edited by any program or is it straight from the camera?

There are a lot of problems with how that file was written.

It's pretty common image straight from the camera can have a few warnings, but 25 is excessive.  The not allowed in JPEG tags aren't worth worrying about, but all the Non-standard wranings are a problem.

I think I would use a command like this to try and find/fix the problem files.  This is set to rewrite any file with more than 10 warnings but change that to a value you feel comfortable with.  If on Mac/Linux or Windows PowerShell, change the double quotes into single quotes
exiftool.exe  -ext jpg -if "${Validate;m/^(\d+)/;$_=$1} > 10" -EXIF:all= -tagsfromfile @ -EXIF:all -unsafe -r C:\Temp\aaa\

Do NOT run this command on any RAW file type (.NEF, .CR2, .ARW, ext) as the file may be damaged by rewriting the EXIF block.  The -ext jpg option will make sure it is only run on jpgs.

Hello,
I'm not sure, these are very old pictures, probably they've been modified by Picasa and other softwares.
I tried running your code in a small group of pictures and it seems it worked.
I will try to run it on all of the pictures.
Thank you for your help

I'm not sure, these are very old pictures, probably they've been modified by Picasa and other softwares.

While Picasa will delete MakerNotes in certain cameras, most notably Nikon MakerNotes, in my experience it always seemed to correctly write EXIF and other metadata groups correctly.
