The watermark function begins to appear in the PHOTOSHOP40 version, This feature is retained in the 5.0 and later versions, simply to add a watermark to the image, the image of the author can add copyright information and contact telephone information, to remind users to pay attention to the copyright ownership of the image, but also to allow users to communicate with the author, the image of the watermark in the image of the special Channel (channel) , it does not affect the image, nor does it affect the watermark because of the manipulation of the image. Before using this technology, you have to register in Digimarction, Digimarc create a database of artists, designers, cameras, and their personal information, only in this way, users can obtain a personal authentication number, you can use this number and access rights as a watermark into the image, When you open an image, Photoshop automatically searches for watermarks each time, such as Photoshop, which displays the copyright information on the title bar, and alerts the user to read the watermark to find out who owns the image.
The watermark function of Photoshop is divided into two kinds of embedding and reading watermark, the following is introduced separately:
An embedded watermark
1, open an image file, it should be noted that for a file, you write a watermark opportunity only once.
2, select [Filter]/digimarc/embedded watermark] menu, will come out a registration information.
3, if you are the first time to use the Watermark function, the registration window will display PICTUREMARC demo version, you can click the Personal Registration button, through the Web browser will take you into the DIGIMARC node to obtain the user's personal authentication number (Creatorid), If your e-oral English is considered to be first-rate, you can also obtain the personal authentication number by contacting Digimarc by telephone. But frankly, I don't think it means much, cumbersome registration procedures I don't believe you stick it out, other copyright years, image properties, watermark durability can be customized as appropriate. 4, click OK to complete the embedded watermark.
Second, read watermark
1, the same, open the image, 3lian material, select the filter ytterbium/digimarc menu Read watermark, if Photoshop found watermark, a dialog box will show the author's identity, your use of permissions and other personal information.
2, the previous step you have a preliminary communication with the author, if you want to get more information, you can click on the Web query, through the Web browser can be queried by the author of the information registered on the DIGIMARC. If your purpose is for commercial purposes, you can also call the author directly from a Web query if necessary to obtain the author's authorization.
The
Watermark function shows its function in some commercial situations, it greatly facilitates the communication between the user and the author, now is not all the copyright, this is a kind of big trend, and the watermark function also solves the dispute of the image usage authority effectively. Said so much for our ordinary users: The above mentioned Photoshop watermark function, for us is not much use, as long as we know that this is the line.
