Adding a Watermark to an image

Step 1: Create 2 layers in Adobe Photoshop. One with your image and one with the desired watermark in black.

Step 2: On the layers palette click the effects button at the bottom and select Bevel and Emboss from the pop up menu.

Step 3: Change the size to 2 px (this is for a 72 ppi image)

Step 4: Change the layer mode to Screen. Save for web and you are ready to upload your image to the web.
