I use a program written by a man named Phil Harvey to add EXIF info to my scanned film files. It doesn't come with its own GUI though, so I've been using it from the command line.

Until now.

I got off my duff and wrote a GUI interface for it. It lets me add cameras, makes, models and apply the data to a directory full of scanned jpg files. If anyone would like to use it, you may download it at:

Note, it won't work at all if you haven't downloaded Phil's great tool. Instructions are linked on the program's main screen.
