5. In the lower half of the dialog box, uncheck the Layers option.
Because this file contains layers, this option is probably checked by default. If your
file contained alpha channels, annotations, or spot colors, those check boxes would
also be available. When you uncheck the Layers option, the As a Copy check box is
automatically activated.

Choosing a different
format automatically
changes the file’s
extension.

Turning off the Layers
option automatically
activates the As a
Copy option.

6. Click Save.
Most file formats include additional options, which you should understand before you
simply click OK.

7. In the TIFF Options dialog box, make sure the (Image Compression)
None radio button is selected.
TIFF files can be compressed (made smaller) using
several methods:
• None (as the name implies) applies no
compression to the file. This option is safe
if file size is not an issue, but digital file
transmission often requires files to be smaller
than a full-page, multilayered Photoshop file.
• LZW (Lempel-Ziv-Welch) compression is lossless, which means all file data is
maintained in the compressed file.
• ZIP compression is also lossless, but is not supported by all desktop publishing
software (especially older versions).
• JPEG is a lossy compression scheme, which means some data will be thrown
away to reduce the file size. If you choose JPEG compression, the Quality
options determine how much data can be discarded. Maximum quality means
less data is thrown out and the file is larger. Minimum quality discards the most
data and results in the smaller file size.
