synchronizing JPEGs from different cameras?

my friends and myself came from a trek in the mountains with 100s of
pictures on 4 different cameras. Is there a (free?) software to pull
out the date stamps from the JPEGs and sort them by time accordingly?

Assuming that you are using Windows:
pixvue allows you to add the exif date in the detail view, you can then
sort the list according to that.

Sorting by date is something that should be on your cameras included
program, I think its on all my programs or maybe look at Picassa.

Assuming that all 4 cameras had the correct date and time set, the
photos already have a date and time stamp. If you have a friend with a
Mac, iPhoto will automatically sort the pictures by date and time. It
also has the capability to take any picture(s) with the incorrect date
and/or time and change them in batch mode to a new date and time. If
there are more than one, it will add one minute to each one starting
with the one with the earliest serial number. I routinely use 2 or 3
cameras and use this feature all the time. Sometimes when I change
camera batteries, the date and time reset to the default value. Until I
discover this these photos have the incorrect settings. I use the batch
change feature to correct this.

Won't work unless you synchronized the camera's clocks.

One of many options is to use jhead to change the filenames to be
chronological, then other programs will go through them in filename
order. It can also rotate photos according to the orientation sensor.

jhead -autorot -nf%y%m%d%H%M%S *

I use PIE Studio from Picmeta Softwa

Remember to set your camera clocks accurately to start with, and to the
same time zone!

I use the excellent (and free) Pixfer from
http://www.glasslantern.com/ to copy and rename the files
from the camera or card. Renaming is very flexible including
of course data and time. It has other advantages too, best
try it and see what you think.

I rename to a format that prepends the filename with the
EXIF date/time so "IMG01234.JPG" would become something like
"060904-100350-IMG01234.JPG", which is automatically
sortable by filename. As a side effect it also resolves the
potential problem of duplicate filenames.

It will copy (or move) files on the PC as well as from
cards, so you can use it to reorganose those you've already
copied from the camera(s).

Thank you all! We did synchronize the clocks, and even if we didn't
based on the first several pictures, can't I re-asjust the time stamps?

I've never heard of the orientation sensor. Can anyone tell me more
about it? Is it a standard feature on all cameras? the oldest camera is
~4 years old (Canon powershot S50). The other 3 cameras are more
recent, and are in the same price range.

I will also check is Python has a module for reading timestamps from
JPEGs, then I could write a simple script to sort and rename all files.

If you want to write a script you can do no better than to
use Exiftool (Google for it). It's a Perl script/library
that can do everything you want and then some.

Amongst other things it can alter timestamps including the
ability to apply fixed offsets to a whole series of images
taken with a wrong camera clock setting.
