70 Project 1: Composite Movie AdNavigating the Photoshop File HistoryIn addition to using the Undo command to step back through each previous action, you can use the History panel (Window>History) to navigate back to earlier stages.Every action you take is recorded as a state in the History panel. You can click any state to return to that particular point in the document progression. You can also delete specific states or create a new document from a particular state using the buttons at the bottom of the panel.By default, the History panel stores the last 50 states; older states are automatically deleted. You can change that setting in the Performance pane of the Preferences dialog box. Keep in mind, however, that storing a larger number of states will increase the memory that is required to work with a specific file.Keep the following in mind when using the History panel:%u2022 The default snapshot is the image state when it was first opened. %u2022 The oldest state is at the top of the list. The most recent state appears at the bottom.%u2022 You can save any particular state as a snapshot to prevent it from being deleted when that state is no longer within the number of states that can be stored.%u2022 The history is only stored while the file is open. When you close a file, the history and snapshots are not saved. %u2022 When you select a specific state, the states below it are dimmed so you can see which changes will be discarded if you go back to a particular history state.%u2022 Selecting a state and then changing the image eliminates all states that come after it.%u2022 Deleting a state deletes that state and those after it. However, if you choose Allow Non-Linear History in the History Options dialog box (accessible in the History panel Options menu), deleting a state deletes only that state.If you need to keep a record of a file%u2019s history even after you close the file, you can activate the History Log option in the History & Content Credentials pane of the Preferences dialog box. When this option is checked, you can save the history log as metadata, in a text file, or both. You can also determine the level of detail that will be recorded in the history log.%u2022 Sessions Only records each time you launch or quit, and each time you open and close individual files. %u2022 Concise adds the text that appears in the History panel to the Sessions information.%u2022 Detailed gives you a complete history of all changes made to files.Create new snapshotDelete current stateCreate new documentfrom current stateSnapshot thumbnailsIndividual history statesSource for the History Brush
