Chapter 6: Camera raw files
You can process camera raw files from within Photoshop
  Elements and set certain values that are common to all image 
file formats (such as contrast, tonal range, and sharpness). After you process the raw image files, you can open the file, 
edit it, and then save it in any format supported by Photoshop
  Elements. By processing the raw files, which are like 
digital negatives, and then working on them in Photoshop
  Elements, you can experiment with your images while 
keeping the original “raw” files.

About camera raw image files
A camera raw file contains unprocessed picture data from a camera’s image sensor. Think of camera raw files as photo 
negatives. Many digital cameras can save raw format files. You can open a raw file in Photoshop
  Elements, process it, 
and save it, rather than relying on the camera to process the file. Working with camera raw files lets you set the proper 
white balance, tonal range, contrast, color saturation, and sharpness. 
You can reprocess the file repeatedly to achieve the results you want. Photoshop
  Elements doesn’t save your changes 
to the original raw file; it saves the last settings you specified before importing the file from your camera to your 
computer. 
After processing the raw image file using the features of the Camera Raw dialog box, you open the image in 
Photoshop
  Elements, where you can edit it in the same way that you edit any photo, such as fixing red eye or making 
color adjustments. Then, you can save the file in any format supported by Photoshop
  Elements. It’s best to use PSD. 
To use raw files, you need to set your camera to save files in its own raw file format. When you download the files from 
the camera, they have file extensions like NEF, CRW, and so on. Photoshop Elements can open raw files only from 
supported cameras. Visit the Adobe website to view a list of supported cameras.
