My video series available for sale on DVD or by download, LLightroom CC/6 and 5: Producing Great Output, consists of over 12 hours of training on 57+ 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.
Here is a video that came from the Lightroom 4 version of this series, on the basics of using the Custom Package layout style in the Print module. Everything in this video is also applicable to Lightroom 5, 6 and CC.
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.
