Origin Provides information on the history of the image. To enter the current date in a
short text format, click Today. For Credit, enter the information needed in the credit line for
a copyrighted image. Transmission Reference provides the Associated Press with infor-
mation on the original transmission location of the image. For Urgency, specify the
editorial urgency of the image—not its handling priority.
EXIF Displays information imported from a digital camera, such as the date and time the
picture was taken, resolution, ISO speed rating, f/stop, compression, and exposure time.
For more information about EXIF annotations, see your digital camera documentation.

information from the file.

Adding digital copyright information

You can add copyright information to Photoshop images and notify users that an image is
copyright-protected via a digital watermark that uses Digimarc PictureMarc technology.
The watermark—a digital code added as noise to the image—is generally imperceptible
to the human eye. The watermark is durable in both digital and printed forms, surviving
typical image edits and file format conversions—and is still detectable when the image is
printed and then scanned back into a computer.
Embedding a digital watermark in an image lets viewers obtain complete contact infor-
mation about the creator of the image. This feature is particularly valuable to image
creators who license their work to others. Copying an image with an embedded
watermark also copies the watermark and any information associated with it.
For more detailed information on embedding Digimarc watermarks, refer to the Digimarc
Web site at www.digimarc.com.
Before adding a watermark
Keep in mind the following considerations before embedding a digital watermark in your
image.
Color variation The image must contain some degree of variation or randomness in
color to embed the watermark effectively and imperceptibly. The image cannot consist
mostly or entirely of a single flat color.
Pixel dimensions The Digimarc technology requires a minimum number of pixels to
work. Digimarc recommends the following minimum pixel dimensions for the image to be
watermarked:
100 pixels by 100 pixels if you don't expect the image to be modified or compressed
•
prior to its actual use.
