Adobe Photoshop Help Using Help | Contents | Index Saving and Exporting Images Back 459 TIFF Tagged-Image File Format (TIFF) is used to exchange files between applications and computer platforms.TIFF is a flexible bitmap image format supported by virtually all paint, image-editing, and page-layout applications. Also, virtually all desktop scanners can produce TIFF images. TIFF format supports CMYK, RGB, Lab, indexed-color, and grayscale images with alpha channels and Bitmap-mode images without alpha channels. Photoshop can save layers in a TIFF file; however, if you open the file in another application, only the flattened image is visible. Photoshop can also save annotations, transparency, and multiresolution pyramid data in TIFF format. Adding file information (Photoshop) 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: 1 Choose File > File Info. 2 For Section, select an option for the information you want to enter: General Lets you enter title, author, caption, copyright information, and the owner's URL.
