ADOBE PHOTOSHOP ELEMENTS 4.0 71 User Guide See also "File formats for saving" on page 71 "About PNG-8 format" on page 260 "About PNG-24" on page 261 To save a file in TIFF format 1 Choose File > Save As, and choose TIFF from the format list. 2 Specify a file name and location, select saving options, and click Save. (See "To save changes to the current file" on page 67.) 3 In the TIFF Options dialog box, select options: Image Compression Specifies a method for compressing the composite image data. Pixel Order Choose Interleaved, generally. Byte Order Most recent applications can read files using Mac or Windows byte order. However, if you don't know what kind of program the file may be opened in, select the platform on which the file will be read. Save Image Pyramid Preserves multiresolution information. Photoshop Elements does not provide options for opening multiresolution files; the image opens at the highest resolution within the file. However, Adobe InDesign® and some image servers provide support for opening multiresolution formats. Save Transparency Preserves transparency as an additional alpha channel when the file is opened in another application. (Transparency is always preserved when the file is reopened in Photoshop Elements.) Layer Compression Specifies a method for compressing data for pixels in layers (as opposed to composite data). Many applications cannot read layer data and skip it when opening a TIFF file. Photoshop Elements can read layer data in TIFF files. Although files that include layer data are larger than those that don't, saving layer data eliminates the need to save and manage a separate PSD file to hold the layer data. See also "Understanding file compression" on page 73 "File formats for saving" on page 71 File formats for saving Photoshop Elements can save images in the following file formats: BMP A standard Windows image format. You can specify either Windows or OS/2 format and a bit depth for the image. For 4-bit and 8-bit images using Windows format, you can also specify RLE compression. CompuServe GIF (Graphics Interchange Format) Commonly used to display graphics and small animations in web pages. GIF is a compressed format designed to minimize file size and transfer time. GIF supports only 8-bit color images (256 or fewer colors). You can also save an image as a GIF file using the Save For Web command. (See "To save a file in GIF format" on page 67.) JPEG (Joint Photographic Experts Group) Used to save photographs, JPEG format retains all color information in an image but compresses file size by selectively discarding data. You can choose the level of compression. Higher compression results in lower image quality and a smaller file size; lower compression results in better image quality and a larger file size. JPEG is a standard format for displaying images over the web. (See "To save a file in JPEG format" on page 68.)
