Showing Lost Shadows

You can check the lost shadows by showing underexposure part in different colors. If the shadows are not lost, they are shown in white. If lost, they are shown in another color. For coloring details, refer to "Coloring of lost shadows". The lost shadows of a movie file or an image dust-off data (NDF) cannot be displayed.
About lost shadows
When a black part of object is shown in black, it is called "Lost Shadows". If an object has low contrast and if you adjust the exposure to the bright part of object, the lost shadows may occur. If you adjust the exposure to the dark part of object, the lost highlights may occur due to the overexposure.
  1. Set the view mode to [Image Viewer] and select an image to show lost shadows.
  1. From the [Image] menu, select [Show Lost Shadows].
    The lost shadows of the selected image are shown. For coloring details, refer to "Coloring of lost shadows".
    Lost shadows will remain even if you change the view mode to [Full Screen].
    To stop showing lost shadows, select [Show Lost Shadows] again from the [Image] menu.
