Thank you for reading this. I have imported dozens of photographs for which iPhoto has assigned the wrong date. I want the date to be correct. Currently, I highlight all of the photos I want changed, right click and select edit; so now I am looking at just the handful of photos I want edited. However, I can't seem to then select all of those photos and universally change the date. Rather, I can only change one at a time, which is very frustrating when you have about 100 to change. Any help is appreciated. Edit: Figured it out. Batch changes. Thanks for reading anyway.
