I finally took the plunge and upgraded yesterday to Photos. Now I am confused and have a few questions / concerns. I am not confident enough to trust iCloud yet but am trying Photos locally. However, after conversion to Photos my iPhoto library is 38.71GB yet my new Photos library is 24.26GB. (See attatchment with screen shot) Short of going one by one how can I with confidence know all my photos have in fact been transferred over?
