Other Common Formats
That??™s the big three. You could probably live out the rest of your days only knowing those three
formats, but here are three others you might occasionally run into:
?– JPEG2000 JPEG2000 uses the same basic compression technology as its older
cousin JPG, but it offers better image quality while keeping roughly the same file size.
JPEG2000 has some fans, and it??™s supported by most image-editing programs. On the
other hand, digital cameras still use the JPG format??”so to use JPEG2000, you??™ll have
to convert the images from TIF, JPG, or RAW to JPEG2000 format on the PC, which is
honestly a lot of work. Personally, I think this format is not worth your time or trouble.
?– BMP This is the old standard ???bitmapped??? file format created by Microsoft for Windows.
It can be used for general-purpose storage, for image editing, and as the wallpaper on your
Windows desktop, but it isn??™t generally readable by Macintosh computers, nor is it used
on the Internet, or, well, pretty much anywhere else anymore. The biggest problem: BMP
files tend to be quite large because the format makes no effort to compress the data at all.
In general, the only reason you would ever use this file format anymore is if you want to
display a digital image as the wallpaper on the desktop using an old version of Windows.
