How to create a slideshow from a photobook in "photos 1.0"?
In "photos 1.0" file->export from a photo book project is grayed out therefore I cannot export my photo book content as m4v (slideshow) file or jpeg as I used to do iPhoto 9.6.1. The only option I find is to "print" and save as pdf but cannot create a slideshow from a pdf.
I see how to create a slideshow from an album, but don't know how to create a slideshow out of a photo book project in Photos 1.0.
Please help.
iMac, OS X Yosemite (10.10.2)
