How to bulk add 7 hours to EXIF date on all photos?

[davexm]

Hi all,

Yesterday I was in a little hurry & set the date on my camera, but not the time. I've now got around 200 photos spread throughout the day with the wrong time (the first is 12:00:09!).

Is there a way I can add 7 hours to ALL the photo times?

I know I can bulk change them all to a single time, but I'd rather add 7 hours to each so the data is correct. (It accompanies a log of some sort).

Any ideas? Can this be done with iPhoto or something similar?
:)

Yes you can use iPhoto.
Select your photos, then from the photos menu select batch change.

This will enable you to add 7 hours to all photos, not change them all to a single time:

It shifts all selected photos by how much you change the first photo in relation to it's original time.
