Photoshop CS6 is a great program for creating graphics and photos. However, if you want to zoom in on a particular part of your image, you can use the Zoom tool. To use the Zoom tool, first select the part of your image that you want to zoom in on. Then, press and hold the left mouse button and drag the mouse up or down. The Zoom tool will change its magnification level according to how close you are to the image.
