More often than not, when using Photoshop to zoom in and out of pictures, you find yourself using the scroll bars on the side and bottom of your work space to move back and forth, in and out. Frustrating, isn't it? You zoom in and retouch an area of your photo and then have to zoom out, only to find you need to retouch the image again. So, what do you do? Simple. Simply press the [spacebar] to access the Hand Tool and move around your image in a controlled, fun way.
