Always use metadata in preference to
proprietary solutions when keywording your
images – this approach is more flexible and
helps to keep your options open should you
decide to switch to a different system later on.
In spite of the obvious advantages, metadata
still has its drawbacks, not least the various
standards in current use and the different
ways these are implemented from product to
product.
There is no simple solution, so the
following sections detail the advantages
and disadvantages of the various available
formats. Combined with your own
preferences and the metadata that has
already been applied to your images, these
should help you to develop your own
successful keywording strategy.

Exif – More Than
Just Camera Data
Most digital photographers will have heard of
the Exif (Exchangeable image file format)

metadata standard used by virtually all digital
cameras to save shooting information along
with visual image data. Exif data includes
information relating to the camera
manufacturer, image orientation (i.e., portrait
or landscape), shooting date, aperture and
exposure time. These are standard tags that
are (supposedly!) the same in all digital image
files and can be interpreted by all types of
image management software.
Maker Notes: In addition to standard tags,
image metadata also contains maker notes,
which are additional data fields defined and
filled according to the camera manufacturer’s
own specifications. This is where data such as
the camera model and lens information is
stored. Maker notes vary in their form and
content between manufacturers and camera
models. Making all currently used maker
notes readable would involve an enormous
effort on the part of software manufacturers
and doesn’t make commercial sense. Most
photographers consider maker notes to be a
useful source of additional information, but
