Set the values of the Exposure Warning function by clicking and dragging the shadow and highlight sliders, as desired. When enabled, areas that fall outside the set values will be shown by a color overlay. By default, the highlight warning value is 250 and the shadow warning is not enabled.
Double-click on the highlight and shadow color icons to change the overlay color. The default highlight color is red and the shadow is blue.
The Channel Mode allows you to switch between the relevant shadow and highlight pickers for the default combined RGB channel mode and separate red, green, and blue channels.
Preset output Target Levels for both modes can also be applied by clicking and dragging the appropriate sliders.
The Auto Levels Clipping Thresholds sets a 0.10% threshold for Shadows and Highlights by default. This allows a small number of pixels to clip without reducing the overall contrast and dynamic range of an image. Type in the values to alter the settings. The range is adjustable between 0-10%, although in practical terms it’s unlikely that anything approaching 1% and above would be necessary. Note, the Auto Levels Clipping Thresholds deliver the specified percentage of clipped pixels precisely.
Click on the Defaults button to reset the settings.
