Set Zoom tool preferences
Some of the Zoom tool preferences require that your computer has OpenGL. If your computer has OpenGL, be sure
to enable it in Photoshop. Choose Edit > Preferences
> Performance (Windows) or Photoshop > Preferences >
Performance (Mac OS), and then select Enable OpenGL Drawing under the GPU Settings.
❖ Edit > Preferences > General (Windows) or Photoshop > Preferences > General (Mac OS) and then do any of the
following:
• To enable continuous zooming in or out by holding down the Zoom tool, select Animated Zoom. Zooming from
one magnification to another will also be smooth when clicking with the Zoom tool.
• To enable zooming in or out using the scroll wheel on your mouse, select the Zoom With Scroll Wheel option.
• To enable centering the zoom view on the click location, select the Zoom Clicked Point To Center option.
Zoom into or out of multiple images
1 Open one or more images, or open one image in multiple windows.
2 Choose Window > Arrange > Tile to display the images edge to edge.
3 Select the Zoom tool, and then do one of the following:
• Select Zoom All Windows in the options bar, and then click one of the images. The other images zoom in or out at
the same time.
• Choose Window > Arrange > Match Zoom. Hold down the Shift key and click one of the images. The other images
zoom in or out at the same magnification.
Magnify by dragging
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 while dragging.
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:
• If the entire image originally fit within the document window, the image zooms in to fit the window.
• 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.
