Understanding Image Versions
Whenever you work on an image, you are working with an image version, never the
master file. Each time you copy an image, you create a new version. When an image
has multiple versions, all versions are stacked together.
Aperture keeps all your image versions together so that you can view or work with
them whenever you wish. For example, you might open a stack and select a specific
image version to copy. The entire stack appears in all the different projects or albums
in which the image appears.
The instant you change a version in an album, a new version is added to the stack.
The first image in the stack is the pick and represents the stack, and is the image
you work with when you select the version stack in your album. You can also
specify that one of the versions in a stack is the pick for a specific album. You can
select the pick you want and make it the album pick, and that image appears with
an album pick icon. The pick is specific to the album it’s in. The original pick
remains selected in the other locations.
When you open a stack, you can reorder the image versions however you like.
Dragging an image version to the first position makes it the pick. You can reorder,
or promote or demote, the versions according to your needs. For more information
about stacks, see Chapter 9, “Stacking Images and Making Picks,” on page 105.
