I've just returned from a trip to NYC and remembered to adjust the clock on my 5D to NYC time. However i managed to get it 12hours out. so my shots taken in mid afternoon have a time recorded of 02:10 ie early hours of morning. I forgot to change the clock on my A85 compact so they're all 5 hours out. When i sort my photos by date order it tells me that some were taken on 19Nov at 1159pm, then 2 mins later it's 20Nov at 12:01am when in actual fact it should have been 19Nov at 1159am and the second shot the same date at 1201pm. The question i have is, is it possible to amend the time a digital photo was taken so i can adjust the time to the correct one? If it can be done is it easy and can i do a blanket change or must they be done individually??
