I have just put together a wedding album using Apple Aperture and sent it to print. I have used Aperture for book printing in the past and the quality of the finished items is excellent.
Sadly Aperture insists on scrambling the layout of the Album in the event that an alternative theme is needed. i.e. A large Hard Cover Album for the Bride and Groom re-sized as a smaller album for the parents of the bride requires a re-working of pretty much all the pages (100 pages in this case!)
I am disappointed that the software does not seem to have a better option for printing alternative sized versions of a 'finished' album.
