Save a file
If you choose a format that does not support all the features of the document, a warning will appear at the bottom of the dialog box. If you see this warning, it’s best to save a copy of the file in Photoshop format or in another format that supports all of the image data.
You can set a variety of file saving options in the Save As dialog box. The availability of options depends on the image you are saving and the selected file format.
Saves alpha channel information with the image. Disabling this option removes the alpha channels from the saved image.
Preserves all layers in the image. If this option is disabled or unavailable, all visible layers are flattened or merged (depending on the selected format).
Saves spot channel information with the image. Disabling this option removes spot colors from the saved image.
Use Proof Setup, ICC Profile (Windows), or Embed Color Profile (Mac OS)
Creates a color-managed document.
The following image preview and file extension options are available only if Ask When Saving is selected for the Image Previews and Append File Extension (Mac OS) options in the File Handling Preferences dialog box.
Image Previews options (Mac OS)
Saves thumbnail data for the file. Thumbnails appear in the Open dialog box.
File Extension options (Mac OS)
Specifies the format for file extensions. Select Append to add the format’s extension to a filename and Use Lower Case to make the extension lowercase.
Set file saving preferences
Choose an option for saving image previews: Never Save to save files without previews, Always Save to save files with specified previews, or Ask When Saving to assign previews on a file-by-file basis. In Mac OS, you can select one or more preview types. (See Mac OS image preview options.)
saving:specifying file extensions whenfilename extensions, preferences for savingFile Extension (Windows)
Choose an option for the three-character file extensions that indicate a file’s format: Use Upper Case to append file extensions using uppercase characters, or Use Lower Case to append file extensions using lowercase characters.
Append File Extension (Mac OS)
File extensions are necessary for files that you want to use on or transfer to a Windows system. Choose an option for appending extensions to filenames: Never to save files without file extensions, Always to append file extensions to filenames, or Ask When Saving to append file extensions on a file-by-file basis. Select Use Lower Case to append file extensions using lowercase characters.
Save As to Original Folder
When saving, defaults to the folder images originated from. Deselect this option to instead default to the folder you last saved in.
Save in Background (CC, CS6)
Background saving lets you keep working in Photoshop after you choose a Save command. You don’t have to wait for Photoshop to finish saving the file.
In Mac OS, you can select one or more of the following preview types (to speed the saving of files and minimize file size, select only the previews you need).
Saves a 72‑ppi version of the file for use in applications that can open only low-resolution Photoshop images. For non‑EPS files, this is a PICT preview.
Save large documents
Photoshop supports documents up to 300,000 pixels in either dimension and offers three file formats for saving documents with images having more than 30,000 pixels in either dimension. Keep in mind that most other applications, including versions of Photoshop earlier than Photoshop CS, cannot handle files larger than 2 GB or images exceeding 30,000 pixels in either dimension.
Large Document Format (PSB)
Supports documents of any file size. All Photoshop features are preserved in PSB files (though some plug-in filters are unavailable if documents exceed 30,000 pixels in width or height). Currently, PSB files are supported only by Photoshop CS and later.
Supports documents of any pixel dimension or file size, but does not support layers. Large documents saved in the Photoshop Raw format are flattened.
Export layers to files
You can export and save layers as individual files using a variety of formats, including PSD, BMP, JPEG, PDF, Targa, and TIFF. Layers are named automatically as they are saved. You can set options to control the generation of names.
Testing Photoshop images for mobile devices with Adobe Device Central (CS5)
Device Central enables Photoshop users to preview how Photoshop files will look on a variety of mobile devices.
Creative professionals can create Photoshop files specifically for mobile devices and easily test the files. Users can create a document in Photoshop based on a targeted device.
For example, a user interface designer might use Photoshop to create mock‑ups. The designer can test the mock‑ups on a variety of handsets, make necessary adjustments, and pass the improved mock‑ups to developers.
Create mobile content with Adobe Device Central and Photoshop (CS5)
- Select one or more target devices from the Online Library list, and drag them to the Local Library list. Then, select a target device in the Local Library list.
Device Central lists proposed document sizes based on the device or devices you selected (if the devices have different display sizes). Depending on the design or content you are developing, you can create a separate mobile document for each display size or try to find one size appropriate for all devices. When choosing the second approach, you may want to use the smallest or largest suggested document size as a common denominator. You can even specify a custom size at the bottom of the tab.
