A simple CLI to tag film scans with EXIF metadata.

Installation

Requirements

This package uses the pyexiv2 library for EXIF/XMP metadata manipulation, which provides Python bindings for the Exiv2 library. The pyexiv2 package includes pre-compiled binaries for most platforms, making installation straightforward without requiring system-level dependencies.

Usage examples

To set the date of all images to 12 June 2019, specifying camera and film as well:

$ filmtagger -d 2019-06-12 -c "Leica M6" -f "E100G" *.jpg

Filmtagger supports fuzzy-matching against its database of cameras and films, so your input strings needn't be exact. Likewise, it attempts to autodetect a variety of date/time input.

Configuration

You may configure your own camera and film definitions to override the system-wide ones.

Create a ~/.config/filmtagger/cameras.toml file that looks like this:

["Mamiya RB67"]
"Exif.Image.Make" = "Mamiya"
"Exif.Image.Model" = "RB67"

And a ~/.config/filmtagger/films.toml like this:

["Ilford HP5 Plus"]
"Exif.Photo.ISOSpeedRatings" = 400
"Xmp.AnalogExif.FilmMaker" = "Ilford"
"Xmp.iptcExt.DigitalSourceType" = "http://cv.iptc.org/newscodes/digitalsourcetype/negativeFilm"

The section headings will be fuzzy-matched from the command-line arguments. The key-value pairs that follow will be set as metadata, assuming they are valid tag names. In addition to the standard Exiv2 tag schema, AnalogExif tags are also supported.
