49. Save an Image in TIFF Format
Before You Begin
47 About Saving Images
As you learned in 47 About Saving Images, TIFF format is a great format for photographic images because it offers lossless compression, meaning that your image data is not discarded during the compression process. In fact, some cameras use TIFF format when saving images in high-quality mode. You should start out by saving an image in Photoshop Elements in PSD format to create a working copy (see 48 Save an Image in Photoshop Format (PSD)). After making all your changes to the image, save the image in a format that's easier to share, such as TIFF.
TIFF format allows you to retain the various separate layers you might have created during the editing process, although you'll probably not want to do so because the layer data is already safely stored in your PSD file. If, however, you are planning to continue your edits on a computer that does not have a program that reads PSD format (such as Photoshop Elements or Photoshop), you can use the layered TIFF format to save your work in progress.
Although layered TIFF format is pretty universally accepted, there are no guarantees that a program will be able to open your image if you save it in that format. So always save your working copy in PSD format.
Turning off the Layers option automatically turns on the As a Copy option; that's just a protection against your accidentally overwriting a file that contains layer information.
If desired, change the filename displayed in the File name box. Normally you do not have to do this because the file will automatically have a different file extension than the original file (the file extension changes because you've chosen a different file type).
Choose File, Save As
In the Editor, open the file you want to convert to TIFF format. The file is probably a PSD-formatted copy of an image to which you've already made changes. Choose File, Save As from the menu bar. The Save As dialog box appears.
Choose TIFF Format
From the Format drop-down list, choose TIFF.
Select Save Options To save the TIFF copy in the catalog and add it to the version set that includes the edited PSD copy and the original file, enable both the Include in Organizer and Save in Version Set with Original check boxes. See 47 About Saving Images for help in selecting other options.
Select options as needed. For example, if you're resaving a PSD file to TIFF format because you're through making changes, you will most likely want to disable the Layers check box. This action merges the layers together into a single-layered image, and does not save the layers separately. Because the layers are preserved in the PSD file, you won't need the separate layers in the TIFF file as well.
Click the Save button. If you see a note reminding you that you're saving this image as part of a version set, click OK to continue. The TIFF Options dialog box appears.
Set TIFF Options and Click OK
Select an Image Compression. Compressing a file reduces its size; however, as long as you choose LZW or ZIP, you can compress your file without sacrificing image data. Between the two, TIFF-LZW compression is probably more universally accepted; TIFF-ZIP compression might not be compatible with older programs. If you choose JPEG compression, select a Quality level from the drop-down list and drag the slider to fine-tune the level of compression.
Select a Byte Order. You can usually leave this set to IBM PC, but if you know that this image is destined for use on a Macintosh, you should select Macintosh instead.
To save multiple resolutions of your image in the TIFF file, enable the Save Image Pyramid option. Some programs might then be able to display your image in the resolution you select when it's opened; Photoshop Elements simply displays such an image at its highest resolution. If the image has transparent pixels in it and you want to preserve them, enable the Save Transparency option. TIFF transparency is not compatible with all programs, so you might not want to use it.
In the Layer Compression frame, the Discard Layers and Save a Copy option is normally enabled. However, if you enabled the Layers option in the Save As dialog box, you can choose how those layers are saved in the TIFF file. Select RLE to create a file that's quicker to save yet larger; select ZIP for a smaller file that takes a bit longer to save. When you're satisfied with your selections, click OK.
The file is saved. If the As a Copy option was enabled in the Save As dialog box, your original PSD file is still open; the TIFF copy is saved to disk and closed automatically. Click Save on the Shortcuts bar to make sure that your final edits are preserved in the PSD file, then click the Close button on the PSD image to close it as well.
