If you download the latest Lightroom Release Candidate 2 from the Adobe labs site you will notice that you can now export JPEG files from the book module!
How do I transfer a book I started in Lightroom 4 from one computer to another?
You can select the saved book project in the Library module and export it as a catalog.
Love learning from you at PS World and WPPi…. But please help me understand… what is the point of making book layouts if you have no customization and are limited to blurb? What is the point of exporting jpgs if you have no control over the size of the pages and book? Great module concept… Just seriously deficient.
There is always room for improvement- please post your feedback to one of these forums so that the product team can see it:
