changing your photo's exif data

flowers and the bees

If you have one of those digital camera’s that forgets what day it is after you’ve replaced the AA batteries you might end up with a lot of pictures with bad EXIF data tags.

As a geek and nitpicker I sort of dislike that. In fact, in Picasa all of those pictures ended up being cataloged in the year 2012 which is the default date of the camera apparently. Picasa I found out uses EXIF data and not the file date of your pictures. This makes sense of course. If you change a photo’s color settings for instance, the file date will change, the EXIF data won’t.

So to fix those bad dates I ran into this piece of software called EXIFViewer. The GUI look pretty damn old, but it works, so who cares. You can use it to set the EXIF date to a specific date and time, or perform a calculation on the selected files. For instance you can subtract 2015 days from all files, and whoosh those files back in time to when they where actually shot.

I also found some links to more EXIF data changing software is on Flickr. I haven’t tried any of these myself, but it might be worth a look. There’s a command line based tool in there as well, so if you want to do some scripting, that might be what you need.
