changing multiple photo dates

Hi,

While reviewing all my photos from the summer, i realized that all of their dates said x/x/2005, instead of 2006. I checked my camera, and sure enough my settings were wrong. Now I want to change all of their dates to 2006. I know how to do a batch change, but it seems like this will make them all uniform. I want them to maintain their month and day information, but just change everything to 2006.

any ideas?

 

um i guess the EXIF data (whatever that means), the filename seems random. I know how to change the date to individual photos, or change many photos to the same date. I need to push a lot of photos a year into the future.

 

hmm i appreciate the link and the help, but that seems way to complicated for what i'm trying to do. anyone know of a simpler solution? maybe within iphoto?
