To update previews to use new size and compression settings: 1 In the Browser, select the images you want to update. 2 Hold down the Option key, Control-click the image selection, and choose Generate Previews from the shortcut menu. If you encounter performance issues, you can check the Activity window to see if Aperture is doing work in the background (choose Window > Activity). If you think that preview processing may be degrading performance, you can disable automatic preview maintenance for that project and cancel the preview processing task underway. You can then generate the previews at a more convenient time. Sample Workflows for Using Previews Effectively There are several methods for using preview images efficiently and effectively. Generating Previews on a Project-by-Project Basis for Large Libraries Because previews can take a long time to render (especially for high-resolution images or heavily adjusted ones), it may be best to disable automatic preview maintenance for a large library, and instead select the projects for which you want previews created. To stop building previews library-wide and build previews on a project-by-project basis: 1 Choose Window > Show Activity. 2 Select the "Processing previews" task, then click the Cancel Task button. 3 Close the Activity window. 4 In the Projects inspector, select Library and choose Maintain Previews For All Projects from the Project Action pop-up menu (with a gear icon). No checkmark or dash (-) next to the menu item indicates that preview maintenance is disabled for the entire library. 5 In the Projects inspector, individually select the projects for which you want previews created, then do one of the following: Â Control-click each project and choose Update Previews for Project from the shortcut menu. Â Select each project and choose Maintain Previews for Project from the Project Action pop-up menu (with a gear icon). A checkmark next to the Maintain Previews for Project menu item indicates that preview maintenance is enabled for the selected project. 202 Part II Photo Editing
