This tutorial will show you a quick way to apply your copyright watermark to an image using photoshop brush.
Step 1: We'll be starting off by creating a new document (file>new>new document). Don't worry about the document size, it does not really matter as you will always be able to resize your brush when you need it later on.
Step 2: Create a new layer (layer>new>layer), and get a copyright symbol on your new document by a). choosing Custom Shape Tool on your Tools Palette then b). Click on the third icon on the left to create custom shapes using pixels rather than paths, c). Choose the copyright symbol from the default set of shapes.
Step 3: Write your copyright info on the same layer with the Type tool
Step 4: Get your Rectangular Marquee tool (M), and click-and-drag a selection around your copyright symbol and info. Choose Define Brush Preset (edit>Define Brush Preset) and name your brush.
Step 5: Now it's time to use your new brush. Open a photo, choose the Brush Tool from your tools palette, choose your copyright brush from your Brush Picker, create a new layer from your photo and click once where you want your copyright info to appear.
Step 6: You can change the opacity of the layer to get your copyright info transparent
