Showing Lost Highlights

You can check the lost highlights by showing overexposure part in different colors. If the highlight is not lost, it is shown in black. If lost, it is shown in another color. For coloring details, refer to "Coloring of lost highlights". The lost highlights of a movie file or an image dust-off data (NDF) cannot be displayed.
About lost highlights
When a bright part of object is shown in white, it is called "Lost Highlights". If an object has high contrast and if you adjust the exposure to the dark parts of the object, lost highlights may occur. If you adjust the exposure to the bright part of the object, the lost shadows may occur due to underexposure.
