If you’re like most people, you probably zoom in and out of photos and images in Photoshop using the mouse wheel. But what if you have a mouse with a scroll wheel? Photoshop has a built-in zoom feature that lets you zoom in or out using the scroll wheel. To use this feature, first make sure that the Zoom tool is selected on the toolbar. Then click and hold down the left mouse button on an image area that you want to zoom in on. While holding down the left mouse button, drag your cursor up or down to change your magnification level. To zoom out, release the left mouse button and drag it left or right.
