Camera Raw never makes any changes to your actual raw file. In fact, it's not possible to make changes to a raw file, because it doesn't contain any finished image data. The adjustments that you make in Camera Raw are stored separately from your image data. What's great about this scheme is that you can go back at any time and change your Camera Raw settings, and then reprocess your raw file. In this way, you can derive lots of different corrections from the same file.
After you're done adjusting your settings, you need to decide what you want Camera Raw to do. At the bottom of the dialog are four buttons:
- Done: This button saves your settings (in either the internal database or as a sidecar XMP file, depending on your settings) and then closes the raw file.
- Open Image: This button does the same thing as the Done button, but also opens the image within Photoshop.
- Cancel: This button discards any adjustments applied to the images and closes the Camera Raw dialog.
- Save Image: This button saves your settings, and then saves the selected images in one of four file formats without leaving the Camera Raw dialog.
