Our current project is creating a presentation Wedding Book.
Each student is required to create six pages as if we were putting together the entire album for a client.
I created a template for a 10"x10" album with true panoramic pages. It's essentially a 20" wide x 10" high page configured for 300 dpi.
I added guides at 1/2" in from each edge and guides for the horizontal center and for the center line between the two pages. I can add an image to fill the background or use solid colors.
The individual images are copied, pasted, re-sized to fit and then saved as a PhotoShop .PSD file.
The current book is a little cramped because I'm trying to jam the whole wedding, about 55 images, into six pages (12 sides). In the real world I'd have about twice as many images and 4 times as many pages to display them.
When the page is finished I convert it to sRGB, flatten it and save it as a Quality 12 JPEG and it's ready to FTP. I retain the .PSD files because, once again in the real world, I'd soft proof the book with the client before committing it to the printer.
