Editing slideshows in Photos
Is it possible to have a slide appear without text at first, then have text appear? It seems like I've done this in the past (perhaps in iPhotos?), but I can't see how to do it now in Photos. I thought of duplicating the photo I want to treat this way, but the 'Duplicate' photo option in the Image menu is greyed out.
