Automatically Naming Your Imported Images
The filenames given to images by the camera are often difficult to distinguish. When
you import images, you can have Aperture use the original name assigned by the
camera, or use a filenaming convention that you choose or create. For example, you
can use a name format that includes a name that you specify, plus the date, time, and
index number. Aperture provides a number of preset name formats, and you can also
create your own naming conventions to suit the different types of shoots you do. You
can choose a preset name format when you import new photos.
Aperture provides the following preset name formats:
