The Complete beginners guide to Adobe Photoshop Lesson #23 - Zoom Tool

The possibility of a strong image enlargement is very important, it makes the processes of elimination of imperfections, detailed cleaning and creation of precise selections hundreds of times simpler.

One way to increase the image is to click on it with the mouse selected with the Zoom Tool, which looks like a magnifying glass. It can be found at the bottom of the Tools panel or selected by pressing the Z key.

Click on the image several times to zoom as far as you need.

When you are ready to zoom out, just click on the image while holding down the Alt key.

You can also change the scale using the keyboard: press Ctrl + (plus) or Ctrl - (minus).

To zoom in on a specific area using the Zoom tool, clear the Drag-and-drop box in the tool attributes panel, and then circle the pixels you want to view closer. As soon as you release the mouse button, the photoshop will enlarge the selected area to the size of the document window.

If your computer's graphics controller supports the OpenGL specification, you can hold down the mouse button while the tool is selected to smoothly zoom in and out.
