Undoing an Accidental Save -Because Photoshop Automatically Create a Snapshot when opening a file, you can “undo” an accidental save by clicking on the snapshot in the History panel, saving the file, and then returning to your current state and choosing to “Save As”.Īutomatically Create New Snapshot When Saving -When saving a document (or Save As), the Save command will be added as a state in the History panel in case you need to access it after making additional changes.

The next time you click the camera icon to create a snapshot the New Snapshot dialog appears where you can choose to create a Snapshot from the Full Document, Merged Layers, or the Current Layer. Snapshot Options -For additional Snapshot options, use the fly-out menu on the History panel and enable “Show New Snapshot Dialog by Default”. Snapshots remain at the top of the History panel (regardless of how many changes are made to the document), until the document is closed.
To save a state from rolling off the History panel, click the camera icon to create a new snapshot of the entire document. Note: This is the state of the document that Photoshop will pull from when painting with the History Brush, Art History Brush, Eraser, and Fill Commands.Ĭreating Additional Snapshots -Depending on your preferences and the number of changes made to the file, history states may eventually “roll off the top” of the panel. Snapshots -When Photoshop opens a document, it takes (by default) a “Snapshot” of the document that appears at the top of the History panel. Now, even after going back and time and then making additional changes, the previous states in history will remain.ĭuplicating History States -Option -click (Mac) | Alt -click (Win) a history state (except for the current state) to duplicate it. To retain the more recent states, select History Options from the History panel’s fly-out and enable Non linear History.
By default, if you go back in time and then execute another command, you loose the history states from the currently targeted state forwards (or towards the bottom of the panel). That is, the oldest state is at the top of the list, the most recent one at the bottom. Non Linear History -History states are added from the top down in the History panel. Layer Visibility -If you often toggle the visibility of layers but don’t want them to count as a step in history, use the History panel’s fly-out menu to select History options and uncheck “Make Layer Visibility Changes Undoable”.
Therefore, if you increase the number of states and notice a performance hit, trying lowering the number again. Note: making changes to the entire document (adding layers, running filters etc.), requires Photoshop to keep track of more information for each history state than changes made to only a portion of the image (such as small, localized paint strokes). Setting a higher number will save more changes (history states), allowing you to step farther back in time, however it will also require Photoshop to keep track of more information in RAM (or, when all of the RAM is in use, to the scratch disk). Setting the number of History States -To set the number of history states that Photoshop keeps track of while an image is open, select Preferences > Performance. Command + Option + Z (Mac) | Control + Alt + Z (Win) toggles the last state off/on (after the most recent command).Command + Shift + Z (Mac) | Control + Shift + Z (Win) moves forward in time.Command + Z (Mac) | Control + Z (Win) steps back in time.Time Travel -While you can choose to use the History panel or the edit menu to travel through time, I find it easier to use the following shortcuts: Let’s see how they can help us to make the most our of the past, present, and future in Photoshop! The History panel, however, in conjunction with the History Brush, Art History Brush, Snapshots, Eraser, and Fill Command is far more powerful then simply traveling back through time in your document. When most people think of the History panel in Photoshop, they think of multiple undo.
