I am trying to learn the use of Photos in Yosemite. I am familiar with iPhoto and iMovie for my IMac, Mountain Lion. I must say, that I am having a rough time with the learning curve. I can't seem to do anything on Photos as I once did on IPhoto! Very frustrating. I am trying to learn this new system, so as to be a help with questions from family members from time to time. Good luck with that. Is there some tutorial i can access that can take me step by step in a process of learning the fundamentals of Photos and then IMovie for Yosemite? I am just floundering around on these applications trying to find my way and it is just frustrating. For instance, I have been trying to rid the "Faces" album in Photos and I am wondering if it is doable? I ask myself, "Is this really worth the trouble?" I could use some help in finding a tutorial for dummies. Thanks.
