A rotating plate was my idea for shooting two opposite pages one after another. A marble rotating plate for serving cheese can be all right for that. However you would need a v-shaped glass and a book with wide margins between the pages, beacuse a joint of the glass would obscure the middle part. What's more, turning the rotating table 180 degrees will take about the same time as turning a page. On top of that, the positioning of opposite pages will be different for books thicker than pamphlets. So I dismissed the idea, and I shoot all the odd pages first and even pages next.
