Change DATE only in datetimeoriginal

[damage]

I would like to change a DATE part of datetimeoriginal and not the TIME. The DATE should come from a directory name. So far I came only to the solution, where I can reset time like this:

Code Select Expand

exiftool "-datetimeoriginal<${directory} 00:00:00" -r <path>

Is it possible to change DATE only and leave the TIME part intact?

The camera had the wrong date set, but not on all images in a subdirectories (there are hundreds of them). The directory names have all the correct date like "20130102 desc".

You could do it using the advanced formatting feature, like this:

exiftool "-datetimeoriginal<${directory} ${datetimeoriginal;s/.* //}" -r <path>

However, this will only work if the directory name doesn't contain any other numbers.  If it does, it would be necessary to do some formatting of the directory tag as well.

Works like charm, thank you!

Maybe I am missing something but I get this when I try to do this

-bash: ${datetimeoriginal;s/.* //}': bad substitution

am I supposed to be changing any of this information? I am new and I can do what I want this way but what I really want to do is just change the date and leave the time without any directories involved. I've been searching but can't figure this out!

Thank you

On Mac/Linux you must use single quotes instead of double quotes around any argument containing a '$' symbol.

When I received the error I had input this

exiftool '-datetimeoriginal<${directory} ${datetimeoriginal;s/.* //}' -r <path>

Should I place more '?

When I received the error I had input this

exiftool '-datetimeoriginal<${directory} ${datetimeoriginal;s/.* //}' -r <path>

Should I place more '?

'-datetimeoriginal - you've got a erroneous quote glyph there.

Ok, if I understand correctly you are telling me to input this

exiftool 'datetimeoriginal<${directory} ${datetimeoriginal;s/.* //}' -r <path>

But I still get the same error. Basically all I want to do is change the date of a photo but leave the time intact. I want to input the date, not refer it to a different location. I'm sure there is an easy solution but I don't know it.

Thanks

No, I think Alan was telling you to use ' instead of ' and '.  Command shells only respond to simple ASCII quotes:

exiftool '-datetimeoriginal<${directory} ${datetimeoriginal;s/.* //}' -r <path>

Ah ok I understand. Thank you. I input this

exiftool '-datetimeoriginal<${directory} ${datetimeoriginal;s/.* //}' -r

and it says that 1 file has been changed but when I look at all the dates

exiftool -time:all -a -G0:1 -s

They don't seem to have changed. I have also tried replacing directory with a date and I get

    0 image files updated
    1 image files unchanged

[Phil Harvey]

Add the -v2 option to see the details about what was changed.

Do you know how I can change the date on a file while leaving the time intact? I don't want the date to be referred to a different directory, I just want to input the date and leave the time unchanged.

Thanks

Then the command would look like this:

exiftool '-datetimeoriginal<2014:03:02 ${datetimeoriginal;s/.* //}' FILE

where FILE is the name of your file or directory.

Thank you that works great!

Hi,

I want to something similar, but with -AllDates tag

I tried

Code Select Expand

exiftool -m '-AllDates=2014:04:05 ${AllDates;s/.* //}' file

to no avail.  IMHO, the ${....} is complicated.  I would find exiftool easier to use if we could specify the date part or time with a tag, e.g.

Code Select Expand

exiftool -date -AllDates='2014:04:05' file
or

Code Select Expand

exiftool -time -AllDates='12:10:40' file

but maybe the tag has to follow, like

Code Select Expand

exiftool -AllDates='2014:04:05' -d file

I also tried

Code Select Expand

exiftool -date -AllDates='2014:04:05 0:0:0' file
as logically this should leave the time unchanged, but it returned "0 image files updated"

Am I missing something? cheers
