Keep the post-obit in mind when using the History panel:

  • Program-wide changes, such as changes to panels, color settings, deportment, and preferences, are non reflected in the History panel, because they are not changes to a particular paradigm.

  • By default, the History panel lists the previous 20 states. You lot can change the number of remembered states by setting a preference nether Preferences > Performance. Older states are automatically deleted to costless more memory for Photoshop. To proceed a item land throughout your work session, make a snapshot of the state (encounter Make a snapshot of an prototype).

  • Once yous close and reopen the document, all states and snapshots from the final working session are cleared from the panel.

  • Past default, a snapshot of the initial state of the certificate is displayed at the peak of the panel.

  • States are added to the bottom of the list. That is, the oldest land is at the top of the list, the about contempo one at the bottom.

  • Each land is listed with the proper noun of the tool or command used to change the prototype.

  • By default, when yous select a state, u.s. below information technology are dimmed. This way you can hands run across which changes will be discarded if you continue working from the selected country.

  • By default, selecting a state then changing the epitome eliminates all states that come later it.

  • If y’all select a state and then change the prototype, eliminating the states that came after, you tin use the Undo command to disengage the last change and restore the eliminated states.

  • Past default, deleting a country deletes that state and those that came afterward it. If you choose the Allow Not-Linear History option, deleting a country deletes simply that state.

    • Click the proper noun of the land, and cull Delete from the History panel menu to delete that change and those that came afterwards information technology.

    • Elevate the land to the Delete icon
      to delete that change and those that came afterwards it.

    • Cull Articulate History from the panel card to delete the list of states from the History panel, without changing the epitome. This choice doesn’t reduce the amount of memory used by Photoshop.

    • Hold down Alt (Windows) or Choice (Mac Os), and cull Articulate History from the console menu to purge the list of states without changing the paradigm. If you become a bulletin that Photoshop is depression on retentivity, purging states is useful, because the command deletes the states from the Undo buffer and frees upward memory. You can’t undo the Clear History command.

    • Choose Edit > Purge > Histories to purge the listing of states for all open up documents. You lot tin can’t disengage this activeness.

  2. Automatically Create Starting time Snapshot

    Automatically creates a snapshot of the initial state of the image when the document is opened.

Set Edit History Log options

You lot may need to keep careful rail of what’s been washed to a file in Photoshop, either for your own records, client records, or legal purposes. The Edit History Log helps yous keep a textual history of changes fabricated to an prototype. You can view the Edit History Log metadata using Adobe Bridge or the
File Info
dialog box.

You can choose to consign the text to an external log file, or you can store the information in the metadata of edited files. Storing many editing operations as file metadata increases file size; such files may take longer than usual to open and save.

If y’all need to prove that the log file hasn’t been tampered with, keep the edit log in the file’s metadata, so use Adobe Acrobat to digitally sign the log file.

By default, history log information almost each session is saved as metadata embedded in the image file. You can specify where the history log data is saved and the level of detail independent in the history log.

  1. Cull Edit > Preferences > General (Windows) or Photoshop > Preferences > General (Mac Bone).

  2. Click the History Log preference to toggle from on to off or vice versa.

    If you desire to relieve the text file in a unlike location or salvage some other text file, click the Choose push button, specify where to salve the text file, proper name the file if necessary, and click Salve.

  4. From the Edit Log Items menu, choose one of the following options:

    Keeps a tape of each fourth dimension you start or quit Photoshop and each time yous open and shut files (each image’south filename is included). Does non include any data about edits made to the file.

    Detailed

Make a snapshot of an prototype

The Snapshot command lets you make a temporary re-create (or
snapshot) of any land of the image. The new snapshot is added to the listing of snapshots at the top of the History console. Selecting a snapshot lets you lot work from that version of the epitome.

Snapshots are like to the states listed in the History panel, only they offer boosted advantages:

  • Y’all tin can name a snapshot to go far piece of cake to identify.

  • Snapshots can exist stored for an entire work session.

  • You can compare effects easily. For example, you lot can have a snapshot before and after applying a filter. And then select the get-go snapshot, and endeavour the aforementioned filter with different settings. Switch between the snapshots to find the settings you like best.

  • With snapshots, you tin recover your work hands. When y’all experiment with a complex technique or apply an action, take a snapshot commencement. If yous’re not satisfied with the results, yous can select the snapshot to undo all the steps.

Snapshots are not saved with the prototype—closing an image deletes its snapshots. Also, unless y’all select the Allow Not-Linear History option, selecting a snapshot and irresolute the image deletes all of the states currently listed in the History panel.

Pigment with a country or snapshot of an image

The History Castor tool
lets you paint a copy of 1 image state or snapshot into the current image window. This tool makes a copy, or sample, of the prototype and and then paints with information technology.

For case, you might brand a snapshot of a modify you fabricated with a painting tool or filter (with the Full Document pick selected when y’all create the snapshot). Afterwards undoing the change to the prototype, you could use the History Brush tool to utilize the change selectively to areas of the image. Unless y’all select a merged snapshot, the History Brush tool paints from a layer in the selected state to the same layer in another land.

The History Brush tool copies from one state or snapshot to another, but just at the same location. In Photoshop, you can also paint with the Art History Brush tool to create special furnishings.
