                          You can still embed a digital watermark even if you do not have a digital ID using the Image-
                          Bridge Demo (set by default). The watermark will be embedded, but you will not be identified
                          as the copyright holder unless you subscribe to the service.
                          The strength of a watermark depends on the dynamic range of the image itself. Strong water-
                          marks can withstand a great deal of retouching before they are completely wiped out. The image
                          would be so altered by the time the hidden watermark is lost that it wouldn’t be of any value.

                       4. Click OK in the Embed Watermark dialog box. A verification dialog box appears showing that
                          this particular image has a medium-strength watermark. Click OK. If you are prompted to
                          check for an updated version of the Digimarc plug-ins at any time, choose Remind Me Later.
