    Hi,

    Does anybody know the reason why after migrating from Aperture to the new Photos app my photo library has grown around 50GB?

    My Aperture library is 373GB & the new Photos library is 422GB?

    The photos app also includes all the shots taken from your iOS devices, that might explain it.

    Does Photos keep non-destructive edits or does it apply the edits before it transfers to the new library?

    It operates like iPhoto did, in that it stores the edits, if that's what you mean. And in converting an old non-Photos library it should preserve those edits, although whether the edited image will look exactly the same is probably something you should check. It would probably use the same preview, but there might be subtle differences in how it handles some adjustment or other. Mine looked to be the same.

    OK, then it is using the same underlying Core Image system software so the processing is the same.

    One thing that is always true is that when ever you design a data structure there is always a trade off beaten size and speed. Adding a few more index files in the database will make searches go faster but they take space. Also this new app has to allow for access from other Apple devices so there is more "book keeping" to do. The designers have to find a compromise and today disks are cheaper and processors are faster so i'd not be surprised if the compromise solution is different. I guess some one could go into the libraries and look around
