Stuart Smith did you place the config.ini file at ~/.elodie/config.ini? You may have to create that folder if it doesn’t already exist.
You can add support for CR2 by including it in this list. https://github.com/jmathai/elodie/blob/master/elodie/media/photo.py#L31
Support for different RAW formats is included as they come up. So far all of the RAW formats we’ve been asked to support already work. But we’re whitelisting them so we can include them in tests to make sure we don’t break support for a supported format in the future.
