I have a directory tree containing thousands of photos, some taken on my camera, some on my wife's camera, and some obtained from other people. Also there are edited versions of some of the photos. Now I want to correct the time on all the photos taken on my wife's camera, which turns out to have its clock set 1 hour 10 minutes and 54 seconds fast, partly because it's set to BST (my camera is set to GMT to tie up with my GPS logger), and partly (presumably) because its clock has gained 10 minutes in the last 5 years. So what I want to do is to search the whole directory tree (several directory levels deep) for JPG files starting with the characters DSC (this distinguishes photos taken on my wife's camera from those taken on my or other cameras), and to subtract from the EXIF taken time 1 hour 10 minutes and 54 seconds. Ideally I would like to rename the files at the same time (e.g. to change the DSC to DSD) to indicate that the timestamp has been corrected. Can I do this with Exifer? If not, is there an application that I can do this with? Thanks - Rowan Exifer doesn’t quite seem to do what I want.

You definitely DON'T want to tick the "incremental" checkbox in step 5 above. In Exifer, say if you'd said add 9 hours to each photo (difference between US and Europe) for example, without the box ticked it means "add 9 hours to the time/date stored in each photo" (which is what you want) and with the box ticked it means "add 9 hours to the time/date from the last photo". This "incremental" option is appropriate if you get photos from a friend who didn't set the time on their camera at all, so you get 100 files that all say 12:00:00 AM on 1.1.2001 and you know they were taken in order approximately every 5 minutes, but it's not appropriate for adjusting timezones on photos that were correctly timestamped but all need the same offset. By the way, other tools I've used for the same thing: PhotoStudio (also free, easier than Exifer but refuses to touch photos if the EXIF block is bigger than 64KB) and Digital Photo Utilities (a really nice interface for adjusting time/date, except it's so hidden you can barely find it).
