Here are some ideas for future work:
- Allow the user to specify the information clens currently gets from the EXIF info. This way users could correct scanned images as well.

- Use environment variables or a file to store preferences.

- Explore the possibilty of using some EXIF data to devine which lens was used to take the picture. Perhaps something in the EXIF data could be used as a key that could be bound with a value in the preferences. It might not be totally unique, but it may be good enough for users to get value out of it.

- Can the EXIF and JPEG stuff be done with existing libraries?

- How about an installer (or RPM)?
