1. Open a new image by going to File> New Blank File. Choose the Preset Default Photosohp Elements Size. The background contents should also be the default, white. Click OK. Set your colors to the default (black in the foreground, white in the background) by typing D on your keyboard. Then choose the Type tool from the toolbar or get it by typing T on your keyboard. Click on your image to start typing.
2. To make the © using a PC, hold down the Alt key and type 0169. On a Mac, press Option + G. Then type in a copyright notice (your name, your company, etc.) as you want it to appear. Pick a font you like -- you'll be stuck with it.
3. Click anywhere on your image (other than on the type, that is) to get out of typing mode.
4. Then make your custom brush: Choose Edit > Define Brush. Enter a descriptive name for the brush (like MyCopyright), and click OK.
5. From the Options bar at the top of your screen, pull down the Brush menu (it's the down arrow next to the wavy line that shows what kind of brush you're currently using) and scroll to the bottom. The copyright brush you just made is the last on your list. Click on it to select it.
6. To test your new brush, open an image you'd like to stamp. Grab the Brush tool (type B). then click the spot in your image where you want to stamp your copyright. If it's too small to see, increase your brush size.
