Layers in Photoshop give you great control over adjustments on your photographs, and are simple to use once you understand how they work. Check out Digital Photography School for Jodi Friedman’s (MCP Actions) explanation of how to use layers to your advantage. She explains how Layers can be used to create a border, add text, and how to make an adjustment in curves or levels. The advantage of making adjustments with Layers is that the original image remains untouched until you flatten the image you can always change your mind. To save the work with the layers, save the file as a Photoshop file so you can go back and continue to make changes without starting all over again. This can be very helpful when working with text, inevitably there is a change required to the text.
