Holiday pics from 3 cameras, only 1 camera had the correct date/time (one of the other is out by months, the other by a couple hours).

Is there an easy way to correct this on a Mac, without paying for an app? I don’t want to use iPhoto, and would like to correct the dates before importing to Lightroom (plus I don’t think adjusting the capture time in LR changes the EXIF data?)

Ta,

I think you can make those changes in Lightroom.

Edit here you go.

Shame you don’t want to use iPhoto, that would do it easily

Exiftool is probably capable of doing it, depending on your command line skills, I only sussed out how to use it examine the EXIF data and then batch rename all the images in a folder to names based on the date and time the image was taken. But it’s capable of writing EXIF data too.

Changing it in Lightroom doesn’t change the actual photo EXIF data does it, just the time within LR?

Importing to iPhoto you have to create a library etc right?

Anyone? 🙂

Picasa will do it… it’s quite good in this regard, you can set photos to a specific time or adjust lots of photos by a certain amount. I always use it when I inevitably change time zones on one camera but not the other on holiday…

Had a quick Google EXIF tool can shift the date/times, syntax is >>

exiftool “-DateTimeOriginal+=Y:M:D h:m:s” filename.jpg

To shift by 5 hours and 30 mins it would be >>

exiftool “-DateTimeOriginal+=0:0:0 5:30:0” filename.jpg

A negative shift by one day would be >>

exiftool “-DateTimeOriginal-=0:1:0 0:0:0” filename.jpg
