I have an iPhone 5 and a 2009 MacBook Pro. Both are completely up to date on software. I took a couple hundred photos in both horizontal and vertical orientation with my iPhone over the course of a few months. I then put them onto iPhoto on my MacBook Pro and deleted them off of my iPhone after the import so that I could put them back onto my iPhone sorted nicely into events. When I did this, almost half of the pictures imported ono my iPhone rotated either 90° or 180°. There is no way to rotate them once they're in events in your phone. I have looked at a few other threads, but so far I have not been able to find an answer. It's really annoying to have to look at my pictures sideways or upside down... Has anybody else been able to solve this problem? Thanks so much!
