Photos and other graphic images are often saved in one of these formats:➟ TIFF (tagged image file format):If you’re editing
your photo, it’s good to know that TIFF files retain
their integrity better than formats like JPEG. However,
TIFF compression isn’t quite as efficient as some other
formats, which can result in larger files.➟ GIF (graphics interchange format):Files in this for-
mat have fewer colors, so they may work well on a
Web site but aren’t so great for printed photos. Their
smaller sizes make them easier to exchange or share,
although this format is more typically used for logos
or other graphic objects rather than photos.➟ JPEG (Joint Photographic Experts Group):The JPEG
format often offers more options for controlling
image quality. Use the lowest quality to most easily
send JPEGs via e-mail or speed upload to an online
site. Note that with this format, images degrade every
time you save them.Some common movie file formats include these:
➟ MPEG (Moving Picture Experts Group):This format
was developed as an international standard for com-
pression (squeezing memory-hog movies into a
usable form). It’s a common standard with good
compression to save your movies in smaller-sized
files.➟ AVI (Audio Video Interleave):This format was devel-
oped by Microsoft, for Windows. This is probably one
of the most popular formats for playing movie files,
so many players support it.135Chapter 6: Posting Photos and Videos Safely
