This function automatically fixes a picture based on its available picture information and on an analysis of the picture. It does not interfere in matters of exposure level. This function is good for quick batch edits.
You can reach it via Edit | Adjust | Quick Fix [Ctrl+0] in the Browser, and via Adjust | Quick Fix in the Editor.
There are no settings for this function. It performs automatic contrast stretching, local contrast enhancement (and in some cases sharpening), saturation editing, and noise reduction with the help of the picture's EXIF information.
