Parik,

Preview size doesn’t make any difference when making a book in Aperture. When you print or order the book, a PDF is generated at the resolution needed from the Master files. In fact, you don’t have to have Previews turned on at all to use the Book feature.

However if you’re making something in iPhoto, using pictures from the Aperture Library, then you’re exactly right. Calendars, for example, made in iPhoto with Aperture pictures, would be using just the Preview files.

Kathryn,

Not necessarily necessary. Your preview files could be plenty big; it depends on how you’re set up in Aperture. If you have, say, a 12 megapixel or better camera, and you have previews set at half-size (the default), then for things like greetings cards and the small photos in calendars, you should be fine. You might want to export out at full-size the photos for the full Calendar pages though. However, I would imagine (and I don’t know as I haven’t used it) that if you tried to use a photo that was too low resolution, it would warn you (like Aperture does).

I just tried to try it, and curiously, my iPhoto is missing Calendars in the Create menu. Trés bizarre.
