To identify your images that will be online use Photoshop’s File Info. function. This metadata survives saves down to .jpg, .png, etc. Tip: save a generic XMP file with information that will be for all your images to save time when setting file info. on future images. Just import the XMP file when needed and fill in specific info. about that image.
From the Photoshop tutorial on File info.:
- File information–also called metadata–is increasingly important in all types of publishing. 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.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. The information you add is embedded in the file using XMP (eXtensible Metadata Platform). XMP provides Adobe applications and workflow partners with a common XML framework that standardizes the creation, processing, and interchange of document metadata across publishing workflows.
To enter information about a file:
- Choose File > File Info.
- For Section, select an option for the information you want to enter:
Lets you enter title, author, caption, copyright information, and the owner’s URL. To display a copyright symbol in the title bar of the image window, choose Copyrighted Work in the Copyright Status menu. If Photoshop detects a Digimarc watermark in the image, the Copyright Notice section is automatically updated.
Note: To print the caption under an Adobe Photoshop image, choose File > Print with Preview, and select Caption. Then print as usual. (See Setting output options for more information.)
Provides a way for some image browsers to categorize and search for an image. To add an entry to the keywords list, type in the text box, and click Add. To replace a keyword, select the word in the list, type its replacement, and click Replace. To delete a keyword, select the word, and click Delete.
Lets you enter a three-letter Associated Press code. (Where available, the Associated Press regional registry maintains a list of categories.) To include the image in supplemental categories, type the code, and click Add. To replace a category, select the code, type its replacement, and click Replace. To delete a category, select the code, and click Delete.
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 information on the original transmission location of the image. For Urgency, specify the editorial urgency of the image–not its handling priority.
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.
To load, save, or append file information:
- Click Load to replace the current information with information stored in a File Info file. You can load either an XMP file or an FFO file created by a previous version of Photoshop.
- Click Save to save the current file information in an XMP file for later use.
- Click Append to add information stored in a File Info file to the current file information. For each File Info field, if the field does not contain information then it will be updated with contents from the file. Caption and Keywords will always be appended with the information from the file.
- 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 detailed information on embedding Digimarc watermarks, refer to the Digimarc Web site at www.digimarc.com.
