Writing EXIF tags is a different problem from reading them, and a much easier
one, IMHO.  I know some digital cameras are Linux-based, but certainly
not the cheaper ones.

The libexif web site contains a few pointers to EXIF specifications and of
course the API.  libexif makes design decisions that assume a reasonable
amount of RAM is available.  You could write an EXIF parser that requires
much less RAM if you wanted to, but it would have other trade offs.  You
still haven't said what you're trying to accomplish, so it's hard to give
more specific suggestions.
