Digital Photography Related - Digital Watermarking Processing
Digital Watermarking is the process of adding information into a digital signal -- audio, images or video. If the signal is copied, then the information is also carried in the copy. The purpose of watermarking is to provide copyright protection for intellectual property that's in digital format and to discourage the unauthorized use of the digital signal.
Visible watermarking :
Visible watermarking is a visible translucent image, which is overlaid on the image. It could be your name, copyright, comment, website address, your logo, text or graphical objects. Image filters, dates, photo details and other EXIF information, which holds the rights to the primary image can also be used for image watermarking. Watermarking processing allows the primary image to be viewed, but still marks it clearly as the property of the owning organization.
Invisible watermarking :
Invisible
watermarking is the digital data that is added to audio, images or
video. But it cannot be perceived as such. Because of its different
applications, there are two very different types of invisible
watermarking.
Invisible watermarking, which is destroyed when the image is
manipulated digitally in any way may be useful in proving authenticity
of an image. If the watermark is still intact, then the image has not
been "doctored." If the watermark has been destroyed, then the image
has been tampered with. Such a technology might be important, for
example, in admitting digital images as evidence in court.
Invisible watermarking, which is very resistant to
destruction under any image manipulation might be useful in verifying
ownership of an image suspected of misappropriation. Digital detection
of the watermark would indicate the source of the image.
While there are many ways to protect images, watermarking is probably the most effective way to protect your images. As a professional photographer, if you want to protect your images that published on the Internet, you need a good and easy to use watermarking software to watermarking your images. And WinWatermark may be the best program that allows you to watermark a batch of several images at once.
