CHAPTER 7 FILES AND FILE FORMATS 93■ Byte Order: IBM PC. Determines how the TIFF file is saved. This setting and
the Macintosh setting are no longer an issue unless you are working with
older software. Most new image-editing software can accommodate both file
formats. For example, you can save an image as a TIFF file in iPhoto and
open it in Photoshop Elements on a PC with no problems. Older versions of
Photoshop would ask for the correct byte order before opening.
■ Byte Order: Macintosh. Determines how the TIFF file is saved. This setting
isn’t necessary any longer; most modern image-editing software can accom-
modate TIFF files saved in Macintosh or PC format. Leave the setting as PC
for images.
■ Save Image Pyramid. Creates or preserves multiresolution versions of the
file. This option is designed for page-layout software such as FrameMaker,
InDesign, and QuarkXPress. Page layout designers often want to place a low-
resolution version of an image so that page updates do not slow to a crawl
every time you change layout or text. Photoshop, Photoshop Elements, and
most image-editing software always open the largest version of a TIFF file
saved with an image pyramid.
■ Save Transparency. Preserves transparency as an additional alpha chan-
nel when the file is opened in another application. (Transparency is always
preserved when the file is reopened in Photoshop Elements or ImageReady.)FIGURE 7.7
