Are you suggesting that I just use the unified library feature rather than creating a new Aperture one? I guess there isno benefit.
I have iPhoto events created by Project/occasion such as birthday, Christmas,vacation etc. totaling up to 255 events. I wonder how much more organized aperture will help me.
Is tagging with colors or keywords really useful. I may try and clean up photos. I keep every photo I take. Perhaps I should limit it to only the best ones. Kinda hard.
I migrated to A3 a few years ago... so my experience is not too recent. As I think about it... I guess I would probably use the feature inside A3 to import the pictures directly from iPhoto. This will give you a brand new A3 library with a fresh start. I would suggest using the mode where each of your "iPhoto events" will be a new A3 project. Within A3, the "project" is the basic organization element... and each photo lives in exactly one project.
You can move your photos between projects without any concern... it will simply move between them and continue to live in just one project.
You can create albums with collections of pictures from multiple projects. For example... you can create a project called "All Christmas"... and have all of your christmas pictures in that album. Albums contain "versions" of your originals. They take up essentially zero space. The originals still reside in your projects. If you edit a photo anywhere... all of the versions will be updated.
The real orgainzation begins when you rate, stack, stack pick, etc your pictures. You can also assign locations (trivial to do at the project level assuming your project is taken at approximately the same place. I personally do not use colors.. but I do use tags.
After you do all of this, you can trivially create smart albums that are instantly created with criteria such as "all pictures taken at the coast, rated 3* or better, and have at least one family member in the picture. That new smart album would take almost zero space... and as you add new projects year to year... the smart album will auto populate. From there you can have it auto make slide shows that play on your computer or Apple TV.
This is just a tiny example of what you might do once you move to A3.
