Another type of watermark is the digital watermark, pioneered by Digimarc Corporation. Digimarc offers a service for embedding digital code into photos and other media that is undetectable during normal use, but enables tracking and identification of the media.
But can't a visible watermark be removed?Yes, a visible watermark can be removed with a lot of time and patience, but generally not easily and not without leaving tell-tale signs behind. The collective opinion is that the kind of people that would steal images to claim as their own are acting out of laziness and would be unlikely to bother with trying to remove a well-placed watermark. Many of the people who take images are simply clueless about copyrights and they think anything on the Internet is free for the taking.

Tips for Effective WatermarkingIf you are going to use a watermark, care should be taken to ensure that the watermark is effective, not only for proving that an image was modified, but also for educating the would-be pirates about copyright and ownership. Ideally, the watermark should be a copyright symbol along with the name of the owner, and the URL of the owner's web site, if applicable. This not only conveys the message of copyright, but it gives others an opportunity to contact the original owner of the image.
Watermark placement can be a bit of a balancing act. The watermark should be placed carefully so as not to detract from the image too much, but you also don't want to place the watermark in a area of solid color or a textured area where removal would be easy to conceal. The example on this page was designed to show an extreme example of watermarking and would be is far too distracting for a portfolio photograph. In practice, the watermark should make up a smaller percentage of the overall image area compared to this example.

From the forum: "Watermarks, in my honest opinion, should not be placed so as to destroy the artistic integrity of a picture. The raccoons sample was somewhat spoiled by that whacking big SAMPLE watermark, when I think that a simple text URL and copyright notice across the bottom would have done just as well." -Posted by Daniel
