CCITT
is a family of lossless compression
techniques for black-and-white images. CCITT is
an abbreviation for the French spelling of Interna-
tional Telegraph and Telekeyed Consultive
Committee.
ZIP
encoding is a lossless compression technique.
Like LZW, ZIP compression is most effective for
images that contain large areas of a single color.
Setting preferences for saving
files
In Photoshop Elements, 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:
Image Previews
Choose an option for saving
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 also 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.
•
Windows Thumbnail to save a preview that can
display on Windows systems.
•
Full Size to save a 72-ppi version of the file for
use in applications that can only open low-
resolution Photoshop Elements images. For
non-EPS files, this is a PICT preview.
File Extension (Windows)
Choose an option for
the three-character file extensions that indicate a
file’s format: Use Upper Case to append file exten-
sions using uppercase characters or Use Lower
Case to append file extensions using lowercase
characters.
Append File Extension (Mac OS)
File extensions
are necessary for files that you want to use on or
transfer to a Windows system. Choose an option
for appending extensions to filenames: Never to
save files without file extensions, Always to append
file extensions to filenames, or Ask When Saving to
append file extensions on a file-by-file basis. Select
Use Lower Case to append file extensions using
lowercase characters.
In Mac OS, to append a file extension to the
current file, hold down Option as you choose a
file format from the Save As dialog box.
Enable advanced TIFF save options
Select this
option to enable layer compression options and
additional image compression options when
saving a TIFF file.

Enter a value
from 0 to 30 to specify how many files are available
in the File > Open Recent submenu. (See
“Opening files” on page 47.)
