I just published ExiFilm, a suite of programs that I use with my large format film workflow, under the GPLv3.
When I'm shooting in the field I carry around a notepad of exposure record forms where I record subject information, luminosity, camera geometry, exposure values, and other notes. This form is included in ExiFilm as a PostScript document.
I scan all of my film at a moderate resolution to JPEG files for digital light-table purposes. It's convenient to have the notes that I took while shooting available with the files, and what better place to store them than in the files themselves. The program ExiFilm is used to enter that information and add to the EXIF tags of the files.
I keep the original sheet film in a three ring binder, so to make the same information conveniently accessible with the film, the package includes a program that sets the metadata in the exposure record form and produces PostScript output of four exposure forms that I bind in right behind their corresponding sheet film.
From the README:
ExiFilm is a suite of programs that can be used to annotate digital images with information about the film exposure used to create them. In particular, it is designed for use with large format film cameras where the photographer may then scan the film to create a digital copy for a library or for digital processing.
By storing the exposure metadata in EXIF tags of scanned images, the photographer can have electronic access to the same information contained in the written record from the field from within an image viewer. Further processing of the data can be done without the need to store the metadata in a separate database.
The file "lfrecord.ps" is a PostScript file that can be printed on US letter paper (or other sizes). It is a single page of four exposure record forms design for large format photography. The author trims the four forms and binds them together as a notepad to take into the field. The PostScript program is hand-written and can be altered fairly easily.
The Python program "exifilm.py" provides a data entry screen similar to the form in "lfrecord.ps". It takes an optional argument of a path to a directory with JPEG image files. It will provide a drop-down list of JPEG files in the directory, and selecting one of the files will load the EXIF information from that file. In this way it allows the user to quickly enter metadata for a number of scanned film images. The metadata are saved immediately upon loading a new file or exiting the program.
The Python program "printrecord.py" loads the metadata previously entered with "exifilm.py" and produces pages similar to those in "lfrecord.ps" with the metadata typeset into the fields. The resulting file may then be printed and bound into a photo archive with the original film. Example usage:
python printrecord.py /path/to/images 1 16 | lpr
Produces four pages of output including the metadata for image IDs 1 through 16.
