Saving and Exporting Images
Adding file information
(Photoshop)
Adobe Photoshop supports the information
standard developed by the Newspaper Association
of America (NAA) and the International Press
Telecommunications Council (IPTC) to identify
transmitted text and images. This standard
includes entries for captions, keywords, categories,
credits, and origins. The captions and keyword
entries can also be searched by some third-party
image browsers.
In Windows, you can add file information to files
saved in Photoshop, TIFF, JPEG, EPS, and PDF
formats. In Mac OS, you can add file information
to files in any format.
For more information, see "Adding file
information (Photoshop)" in online Help.
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 information
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 information on embedding digital
watermarks, see "Adding digital copyright
information" in online Help.
Setting preferences for saving
files (Photoshop)
In Photoshop, you can set preferences for saving
image previews, using file extensions, and
maximizing file compatibility.
To set file saving preferences:
Choose Edit > Preferences > Saving Files, and set
the following options:
Choose an option for saving
Image Previews
image previews: Never Save to save files without
previews, Always Save to save files with specified
previews, or Ask When Saving to assign previews
on a file-by-file basis.
In Mac OS, you can select one or more of the
following preview types (to speed the saving of
files and minimize file size, select only the previews
you need):
•
Icon to use the preview as a file icon on
the desktop.
•
Macintosh Thumbnail to display the preview in
the Open dialog box.
