The Navigator Panel allows you to “navigate” around your image at large magnifications.

To find it, Click Window -> Navigator.

When your image is enlarged bigger than your Document Window, simply drag the “Red Box” with your mouse to view the desired location within the image.
 

Notice that the magnification of your image shows at the bottom, along with Sliders to reduce and enlarge.

This is also a good time to review some basic navigation “Speed Keys”, as this is where you’ll use them in conjunction with the Navigator Panel.

The History Panel (Undo History in Elements)

 

Use the “History Panel” as well as the “Visibility” and “Trash” Icons in the Layers Panel frequently (discussed later).  These are excellent ways to discover "what-if" scenarios and/or to make instant corrections on your image.

1.  Every time you perform a function that changes your file, a “History State” is created.  Click on the name of your desired location above the last entry to go back in “History”.
 

2.  By default, Photoshop will save 20 History States (50 in Elements).  You can change it in “Preferences” -> Performance”, but probably don’t need to.  Any more history states, and you’ll start to slow down your computer.

3.  If you go back and forth between various History States, and don’t work on and change your image, all the history states that follow are saved.

4.  If you go back to a previous History State, then change your image, all the history states that follow are dumped.

5.  When your image is closed in Photoshop, all of the current History States are lost – This is one reason you work in Adjustment Layers, discussed in last month’s article on Adjustment and Masks Panels.

6.  (Not available in Elements) If you activated the “History Log” in “General Preferences”, a “History Log” is created (including what you did in Adobe Camera RAW, discussed later) in your Metadata.  It can be accessed (with an image opened that you’ve previously worked on) by going to "File” -> ” File Info…” -> “History”.  You may need to scroll across the top to find the History Tab.

Until the next time, have fun and stay well!
