PhotoLab Exiftools
PhotoLab-Exiftools is a set of tools for digital pictures
PhotoLab Exiftools is a separate subset of PhotoLab. It's a separated part of Photolab because one need to install external commande line software (JHead and Jpegtran) and it'll be replaced by Gimp's Python-fu when Gimp will be capable of handling EXIF data from a Python-fu.
Version: 2.1.0 changed january 21 2010, author: Raymond Ostertag, License : GNU/GPL.
Languages: english and french.
Type: Python-fu for Gimp-2, tested with Gimp-2.6.6 under Linux and Windows.
Dependencies: JHead et Jpegtran (only for Autorotate) are needed to manipulate EXIF datas. Gimp-2.6 can't do it yet. JHead is available for Linux, Mac OSX and Windows. Jpegtran is available for Linux and Windows. Here you can find a Jpegtran Mac OSX binary and 7zip set of Windows binaries to download.
Installation : Download 7zip or tar.gz archives. Each archive contain a text help file en english. The Python-fu must be copied in the user directory at .gimp-2.6/plug-ins. Under Linux and Mac they must be executables. JHead et Jpegtran should be installed in a system executable directory (PATH parameter) or in the same directory where gimp were launched (bin).
Translation :
A .pot file is available for translators. Download
gimp20-photolab.pot translate it and send
it back to me in the 
Gimpfr mailbox. I'll add it to the supported languages list.

Autorotate
A batch work to rotate automatically your photos. The cameras have a orientation sensor who fill
the orientation EXIF data. Autorotate apply the command line jhead -autorot to
your photos. The photos are rotated be also the EXIF data is updated.

RenameByDate
A batch work to rename your photos by adding as prefix the date of the shot. The cameras give
the date of the shot in the EXIF datas. RenameByDate apply to your photos the command line
jhead -n%Y%m%d-%H%M%S-%f.

ChangeDate
A batch work to correct the shouting date of your photos. The cameras give
the date of the shot in the EXIF datas. This is only perfect if the camera's internal
date is correctly initialized. ChangeDate apply to your photos the command line
jhead -ta+H:M:S and add or substract a delay to the
shouting date of your photos.

Synchronize_2Cameras
A batch work applying at two sets of photos each taken from an other camera.
The photos have been taken at the same time and your wish is to merge them
in one single album. To order by date your photos you must synchronize the
internal date of the two cameras (with ChangeDate) and then rename the
photos by date (with RenameByDate). Synchronize_2Cameras do the both tasks
and add a merging task in a new folder. You must set manually the date offset
between the internal date of the two cameras.

AutoSynchronize_2Cameras
AutoSynchronize_2Cameras works like Synchronize_2Cameras excepted it's no more
necessary to set manually the date offset between the internal date of the two cameras.
Instead you must take two reference photos at the same time with the two cameras.
The offset is then automatically calculated from the EXIF datas given by the two
cameras.

Strip_Exif
