Don't know if you have realized this but the Categories in AcdSee are
powerful. For example if you create categories like these:
Family
----- Joe
---------- Good Picture
---------- Alone
---------- Reason for Event
----- Jane
---------- Good Picture
---------- Alone
---------- Reason for Event
If you click on Family you will see all the files with the Family.
If you click on Joe you get all the files with Joe
If you click on Alone under Joe you get all the files where Joe was alone
If you click on Alone under Joe and hold down Ctrl while you click on Alone
under Jane you will get all files with Joe or Jane Alone unless you select
Match all where you would get none.
Reason for event is when Joe is the reason the Birthday, Wedding etc. was
held.
I started using this feature in iMatch but I discovered AcdSee works the
same way, but AcdSee also does video files, but the default editor is too
simple (with respect to rotate and crop). Choosing a viewer and simple
editor is tough.
