There are a few ways to change the size of a layer in Photoshop. One way is to use the layer mask. The layer mask is a tool that lets you control how the layer appears. To use the layer mask, click on the little arrow next to the layer name in the Layers palette, and then click on the Edit button. The Edit button will open a dialog box that looks like this: In this dialog box, you can choose how much space to give your new layer. You can either give your new layer all of the space it needs, or you can give it only some of the space. If you give your new layer only some of the space, Photoshop will create a small thumbnail for it in the Layers palette. If you give your new layer all of the space, Photoshop will create a large thumbnail for it in the Layers palette. If you want to change how your new layer appears, click on one of the buttons in this dialog box. The buttons are as follows: The first button is called “Align.” This button changes how your new layer looks when it’s displayed in Photoshop. It can be set to align left or right, top or bottom, left-to-right or right-to-left. The second button is called “Size.” This button changes how big (or small) your new Layer will be when it’s displayed in Photoshop. It can be set to have a default size (which is what we’ll use), or you can choose a different size (if you want). The third button is called “Opacity.” This button affects how much light shows through your new Layer when it’s displayed in Photoshop. It can be set to have 100% opacity (which is what we’ll use), or 0% opacity (which means no light show at all). The fourth and lastbutton is called “Resize.” Thisbutton resizes
