in
the Application bar, and select Standard Screen Mode from the pop-up
menu. To display a full-screen window with a menu bar and a 50% gray background, but no title bar or scroll bars, choose View > Screen Mode > Full Screen Mode With Menu Bar. Or, click the Screen Mode button in the Application bar, and select Full Screen Mode With Menu Bar from the pop-up menu.

Select the Hand tool and drag to pan over the image. To use the Hand tool while another tool is selected, hold down the spacebar as you drag in the image.
Note:
If your computer has OpenGL, you can use the Hand tool to flick the image in the direction you want to view. After a quick mouse gesture, the image will move as if you were continuously dragging. Enable this feature by choosing Edit > Preferences > General (Windows) or Photoshop > Preferences > General (Mac OS) and then select Enable Flick Panning.
Dragging the Hand tool to view another area of an image
You use the Rotate View tool to rotate the canvas non-destructively; it does not transform the image. Rotating the canvas can be useful for any number of reasons, including facilitating easier painting or drawing. (OpenGL is required.)
Note:
You can also use rotate gestures on MacBook computers with multi-touch trackpads.
. (If
the tool isn’t visible, hold down the Hand tool.)For a video on the Rotate View tool and other workspace tips, see www.adobe.com/go/lrvid4001_ps. (Discussion of the Rotate View tool begins at the 5:10 mark.)
If you have a MacBook computer with a multi-touch trackpad, you can use the trackpad to flick, rotate, or zoom images. This functionality can greatly increase your efficiency, but you can disable it if inadvertent changes occur.
You use the Navigator panel to quickly change the view of your artwork using a thumbnail display. The colored box in the Navigator (called the proxy view area) corresponds to the currently viewable area in the window.
-
To display the Navigator panel, select Window > Navigator.
To change the magnification, type a value in the text box, click the Zoom Out or Zoom In button, or drag the zoom slider.
To move the view of an image, drag the proxy view area in the image thumbnail. You can also click the image thumbnail to designate the viewable area.
Tip: To simultaneously set the size and position of the proxy area, Control-drag (Windows) or Command-drag (Mac OS) in the image thumbnail.
To change the color of the proxy view area, select Panel Options from the panel menu. Select a preset color from the Color pop‑up menu, or click the color box to choose a custom color.

Use the Zoom tool 
or
the View menu commands to zoom in or zoom out of an image. When
you use the Zoom tool, each click magnifies or reduces the image
to the next preset percentage and centers the display around the
point you click. When the image has reached its maximum magnification
level of 3200% or minimum size of 1 pixel, the magnifying glass
appears empty.
Note:
To view images most accurately, precisely revealing sharpening, layer effects, and other adjustments, see Display images at 100%.
-
Select the Zoom tool
, and
click either the Zoom In 
orZoom
Out button 
in
the options bar. Then, click the area you want to zoom in or out. Tip: To quickly switch to zoom out mode, hold down Alt (Windows) or Option (Mac OS).
Choose View > Zoom In or View >Zoom Out. The Zoom In or Zoom Out command becomes unavailable when the maximum image magnification or reduction is reached.
Set the zoom level at the lower left corner of the document window or in the Navigator panel.
A zoom setting of 100% provides the most accurate view, because each image pixel is displayed by one monitor pixel. (At other zoom settings, image pixels are interpolated to a different amount of monitor pixels.)
-
Double-click the Zoom tool in the toolbox.
(Creative Cloud) Choose View > 100% or, click 100% in either the Zoom tool or Hand tool options bar.
Choose View > Actual Pixels or, click Actual Pixels in either the Zoom tool or Hand tool options bar.
Enter 100% in the Status Bar and press Enter (Windows) or Return (Mac OS).
Note:
The 100% view of an image displays an image as it will appear in a web browser (at the current monitor resolution).
Note:
To zoom continuously, your video card must support OpenGL, and Animated Zoom must be selected in the General preferences.

With the Zoom tool active, select Resize Windows To Fit in the options bar. The window is resized when you magnify or reduce the view of the image.
When Resize Windows To Fit is deselected (the default), the window maintains a constant size regardless of the image magnification. This can be helpful when using smaller monitors or working with tiled views.
Note:
To automatically resize the window when using keyboard shortcuts for zooming, choose Edit > Preferences > General (Windows) or Photoshop > Preferences > General (Mac OS). Then select the Zoom Resizes Windows.
