Recently I've come to know about Layer comps. They are great way to create and save multiple variations of a document without having multiple files. Can anyone explain how to use/create them? How do they work and why they are useful?
My company has what I consider to be a good video about using layercomps here (third video down): http://www.medialab.com/sitegrinder3/scriptpack/
What is Layer comp :
Designers often create multiple compositions or comps of a page layout to show clients. Using layer comps, you can create, manage, and view multiple versions of a layout in a single Photoshop file From Adobe help guide
How to use them :
See a working example of Layer comp here...
Hope this will help....
