“Versioning in digiKam provides an excellent mechanism for
non-destructive editing, but it does have a tiny quirk that can be
a bit confusing if you are not aware of it. With the Versioning
feature enabled, digiKam automatically displays only the most
recent version of a photo and hides all the previous revisions,
including the original file. This functionality helps to avoid
clutter in the main thumbnail view, but this creature comfort can
also cause panic when you all of a sudden can?t find the original
photos. Fortunately, digiKam provides several ways of solving this
conundrum.”
