Spherizing an image is a process of making the image look more spherical. This can be done in Photoshop by selecting the sphere tool and then clicking on the sphere icon at the bottom of the tool palette. The sphere tool will create a new layer on top of the original image. Next, select the round brush and click on the round icon at the bottom of the brush palette. The round brush will create circles around the original image. To spherize an image even more, select both of these brushes and click on one of them to create a new layer with all three brushes in it. Now, use one of these layers to spherize your image by dragging its center point towards either side or up or down. You can also use this layer to make any other changes you want to make to your spherized image.
