Working Smarter with Photoshop's Adjustment Layers: Jul 21, 2006; The catch phrase "work smarter, not harder" could have been written about Photoshop adjustment layers. If you're not using this Photoshop tool, you're probably costing yourself a lot of time. Adjustment layers are the smart way to apply many of Photoshop's most-often-used adjustments because they don't permanently change the image itself. Imagine being able to undo, remove, or alter an adjustment such as levels at any time without losing all your subsequent work. Helen Bradley shows you how to save time and effort and get better results using Photoshop adjustment layers.
