Changing camera times after the event...

    I have two sets of approximately 2000 photos each, taken with two cameras
    over a period of 10 days or so, many within minutes of each other.

    Camera one has the time 5 minutes ahead of real time and camera two has the
    time 36 minutes ahead of real time. I can tell this because a digital
    railway station clock appears in several photos on both cameras and the
    times can thus be compared.

    How do I batch adjust the times to the correct time and thus when I combine
    the two sets they will appear in sequence when sorted by 'date photo taken'?

    4000 photos would be too onerous to change manually.

    You need a batch EXIF editor. Lightroom 2 would do it. Or Exiftool. Or just
    Google batch Exif editor.

    Well, I tried Exifer which purported to do it, but couldn't figure it out,
    on one set of photos it said there was no EXIF information for a lot of
    them - I guess one of the guys has already run his images through some
    software that stripped them out, curiously however, they still sort
    chronologically accurately when I set Explorer to include the 'date photo
    taken' in the file details and then sort by this criterion.

    I don't have Lightroom, but we have Adobe CS4 at work so I will try there
    tomorrow.

    I'd use jhead for this --- it's a command-line tool on Unix-like
    systems, but I understand it's available for Windows too (although I
    haven't tried it there):

    The usage on a Unix system would be:

    jhead -ta'-0:05' camera1/*.jpg
    jhead -ta'-0:36' camera2/*.jpg
