EXIF replace date-modified with date-taken

[kaz219]

Hello,

I'm using shoebox and this "great" software is using the "date-modified" EXIF field of the photos instead of the "date-taken". I had a lot of wrong dates, and looking at one photo using photoinfo, I found that the date used by shoebox was the one of the field "File date and time", which I suppose stands for the "date-modified" EXIF field.

Does anybody know of a method to batch replace the date-modified field with the value of the date-taken field?

Thanks a lot,

I'm most familiar with jhead http://www.sentex.net/~mwandel/jhead/ so that's what I'd try to build a solution around from within Terminal. There are probably some more GUI friendly ways.

Not bad, it works, without having to build anything around it:
jhead -ta-0:00:01 *.jpg

it reset all dates to the date-taken time (minus 1 second).

But if anybody knows of a GUI thing to reset *all* the exif dates field of many photos at a time, it would be great. Thanks anyway for this hint!
