From time to time I have used either Pages or iPhoto to create a simple catalog of selected photos from my iPhoto library with maybe 6 photos per page. This has become more tedious now that I have converted to Photos. Is there a Mac App that will do this is a similar way to pages but with added features? That is, display albums from Photos, allow the user to select certain photos and create a page with multiple photos, with captions taken from Photos. Then output the page(s) as a PDF file.
