Zoom in or out, Set Zoom tool preferences, Zoom a preset amount, Display images at 100%

Zoom in or out

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%.

Set Zoom tool preferences

1. Choose Edit > Preferences > Performance (Windows) or Photoshop > Preferences > Performance (Mac OS). In the GPU Settings section, select Enable OpenGL Drawing.

Note:

Some Zoom tool preferences require OpenGL. If Enable OpenGL Drawing is unavailable, your video card does not support this technology.

2. In the General preferences, select any of the following:

Animated Zoom

Enables continuous zooming while holding down the Zoom tool

Zoom Resizes Windows

Zoom With Scroll Wheel

Enables zooming with the scroll wheel on your mouse.

Zoom Clicked Point To Center

Centers the zoom view on the clicked location.

Zoom a preset amount

• Do any of the following:

o    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).

o    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.

o    Set the zoom level at the lower left corner of the document window or in the Navigator panel.

Display images at 100%

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.)

• Do one of the following:

o    Double-click the Zoom tool in the toolbox.

o    (Creative Cloud) Choose View > 100% or, click 100% in either the Zoom tool or Hand tool options bar.

o    Choose View > Actual Pixels or, click Actual Pixels in either the Zoom tool or Hand tool options bar.

o    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).

Zoom continuously

Note:
To zoom continuously, your video card must support OpenGL, and Animated Zoom must be selected in the General preferences.

• Select the Zoom tool, and then do any of the following:

o    Click and hold in the image to zoom in. Press Alt (Windows) or Option (Mac OS) to zoom out.

o    In the options bar, select Scrubby Zoom. Then drag to the left in the image to zoom out, or to the right to zoom in.

Magnify a specific area

1. Select the Zoom tool.
2. Drag over the part of the image that you want to magnify.

Dragging the Zoom tool to magnify the view of an image

The area inside the zoom marquee is displayed at the highest possible magnification. To move the marquee around the artwork in Photoshop, begin dragging a marquee and then hold down the spacebar.

Temporarily zoom an image

1. Hold down the H key, and then click in the image and hold down the mouse button.

The current tool changes to the Hand tool, and the image magnification changes as follows:

o    If the entire image originally fit within the document window, the image zooms in to fit the window.

o    If only a portion of the image was originally visible, the image zooms out. Drag the zoom marquee to magnify a different part of the image.

2. Release the mouse button and then the H key.

The image returns to the previous magnification and tool.

Automatically resize the window when zooming

• 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.
