Layer Comps in Adobe Photoshop are a great alternative to Snapshots to save the way your image looks at a particular place in time. You can choose to save the Visibility, Position and Styles. Once you have everything the way you want it, click on the New Comp icon at the bottom of the Layer Comps Panel.
When you have mutiple comps, you can use the arrows to scroll through them. You also can make a change, and click on the Update button for a particular comp.
In addition, you can choose File > Scripts > Save Comps to Files to create separate images of your comps. The real power of Layer Comps comes when you export to InDesign.
When you import any layered Photoshop file to InDesign, either checking the Show Import Options button when you import, or selecting the file and choosing Object > Object Layer Options not only gives you access to the Photoshop Layers, but to the Layer Comps.
