My favorite layout style in Lightroom’s Print module is the Custom Package, which allows us to layout multiple photos on the page. These can be laid out on top of each other, they can overlap, text can be added, etc.. Here are a couple examples — a tryptic that I designed to print, and a collage that I started working on, sized for my computer monitor to use as a desktop background:
My video series available for sale on DVD or by download, Lightroom 4: Producing Great Output, consists of almost 12 hours of training on 55 videos, on everything you need to know to make great prints, photo books, slideshows and web galleries — including not just “the how-to” of Lightroom’s output modules, but also conceptual topics such as color management and size and resolution. (UPDATE: Lightroom 5: Producing Great Output is also now available, with even more content!)
Here is a sample video from the series, on the basics of using the Custom Package layout style in the Print module.
For best quality, after you hit Play, click on the sprocket wheel in the bottom right, and choose 720HD.
(Note that the videos for sale are of much higher quality and resolution.)
The next video in Producing Great Output shows how to use Custom Package to do single-photo printing, and also to size and design a desktop background. Other videos discuss how to print to your printer, print to jpeg, etc.
