CreativeLive - Smart Objects for Beginners

https://www.creativelive.com/class/smart-objects-for-beginners-ben-willmore

Smart Objects is an easy, flexible, non-destructive way to work with layers. Because it preserves an image’s characteristics, Smart Objects allows you to resize, transform, add filters, make composites and more without affecting your original image. In this class, Ben Willmore will show you the basics of Smart Objects, including how to update one image and have those changes propagate to all duplicates, load linked raw files that update when you make changes in Adobe® Lightroom®, and build complex effects onto a placeholder image that can be replaced and then instantly updated. This class has the potential to completely change the way you use Adobe® Photoshop®.
