Photo Library Hack - Using Multiple Libraries

If your Photo Library is getting big and unmanageable, the secret might be to switch to using multiple Libraries, especially when it comes to big event, trips, or unique situations where you have LOTS of pictures and don't want your personal library getting flooded with pics you may only need once or annually.
NOTE: I say "iPhoto" in the video because that is the OLD name for the program. It is now called "PHOTO," thank you to a commenter Tim. S. for the suggested correction to the title of the video.

Hi Karl, nice video. It seems, you make your good advice harder to find than necessesary: You are explaining the app "photos", which millions of people use. But your video title is "iphoto", which no one uses anymore (it has been replaced by "photos"). And: The real benefit of your advice is kind of hidden too (it´s barely mentioned at the end): Apple users are tortured by apple with the "buy-more-icloud-storage"-pop up message. Archiving the bulk of the less perfect fotos into a non-system-library of "photos" (which does not sync through icloud) solves this problem.
