USING PHOTOSHOP ELEMENTS 8
Working with files

Many applications cannot read layer data and skip it when opening a TIFF file. Photoshop

  Elements can read layer 

data in TIFF files. Although files that include layer data are larger than those that don’t, saving layer data eliminates 
the need to save and manage a separate PSD file to hold the layer data. 

Many image file formats compress image data to reduce file size. Lossless compression preserves all image data without 
removing detail; lossy compression removes image data and loses some detail.

The following are commonly used compression techniques:

Lossless compression technique that compresses the transparent portions of each layer in 

images with multiple layers containing transparency.

Lossless compression that provides the best results in compressing images that contain large 

areas of single color.

Lossy compression that provides the best results with photographs.

A family of lossless compression techniques for black-and-white images. 

Lossless compression technique that is most effective for images that contain large areas of a single color.

Choose Photoshop

  Elements Preferences

 

> Saving Files, and set the following options.

Gives you the ability to control how files are saved: 

•

Save Over Current File (default) does not open the Save As dialog box. If you open either the original file or the 
edited copy, the first save overwrites the original (as do all subsequent saves in that edit session).

•

Always Ask opens the Save As dialog box the first time you edit and save the original file. All subsequent saves 
overwrite the previous version until you close the file and then reopen it to make further edits. If you open the 
edited copy, the first save opens the Save As dialog box.

Saves a preview image with the file. Select any one of the following: 

•

Never Save to save files without previews.

•

Select Always Save to save files with specified previews.

•

Ask When Saving to assign previews on a file-by-file basis.

Specifies an option for the three-character file extensions that indicate a file’s format. Generally 

it’s a good idea to keep this option set to Use Lower Case.

Ensures that all the supported raw files are opened with Adobe 

Raw instead of other software. Select this option if you have added other plug-ins to Plug-Ins folder.

Select this option to automatically discard any color profiles used by your digital 

camera. The color profile you use in Photoshop

  Elements is saved with the image.

Saves a composite image in a layered Photoshop file so that it can be imported or 

opened by a wider range of applications: Select Never to skip this step, Always to automatically save the composite, or 
Ask if you’d like to be prompted each time you save a file.

Specifies how many files are available in the File

  > Open Recently Edited File 

submenu. Enter a value from 0 to 30. The default value is 10.
