file formats differ in the way they represent image data (as pixels
or vectors), in compression techniques, and which Photoshop features
they support. To preserve all the Photoshop features in your edited
image (layers, effects, masks, styles, and so forth), it’s best
to save a copy of your image in Photoshop format (PSD). Like most
file formats, PSD can only support files up to 2 GB in size. In
Photoshop, if you are working with document files larger than 2 GB,
you can save your image in the Large Document Format (PSB), Photoshop Raw
(flattened image only), or TIFF (up to 4 GB in size only).<div class="note"><span class="notetitle">Note:  </span>The
DICOM format also supports files larger than 2 GB.</div>
</div>
<p>You can save 16‑bits-per-channel images only in the following
formats using the Save As command: Photoshop, Photoshop PDF, Photoshop
Raw, Large Document Format (PSB), Cineon, PNG, and TIFF. When using
the Save For Web &amp; Devices command with a 16‑bits-per-channel
image, Photoshop automatically converts the image from 16 bits per
channel to&#160;8 bits per channel. </p>
<p>You can save 32‑bits-per-channel images only in the following
formats using the Save As command: Photoshop, Large Document Format
(PSB), OpenEXR, Portable bitmap, Radiance, and TIFF.</p>
<p>You can use the following commands to save&#160;images:</p>
<dl><dt class="dlterm">Save</dt>
<dd>Saves changes
you’ve made to the current file. The file is saved in the current
format.</dd><p class="dlseparator"></p><dt class="dlterm">Save As</dt>
<dd>Saves an
image in a different location or under another filename. The&#160;Save
As command lets you save an image in a different format and with different
options. </dd><p class="dlseparator"></p><dt class="dlterm">Check In</dt>
<dd>Lets
you save different versions of a file and comment on each. This command
is available for an image that is managed by a Version Cue Workspace. <div class="tip"><img src="images/tip_help.png" />If you’re working with a file from an Adobe Version
Cue project, the document title bar provides additional information
about the status of the file.</div></dd><p class="dlseparator"></p><dt class="dlterm">Save For Web &amp; Devices</dt>
