With standard settings, the positive exposure adjustment has the effect on the overexposure area
display: the areas shown are the ones that would be overexposed, if we had taken the shot with this
exposure compensation on the camera. This behavior can be changed by turning off the setting
Preferences – Exposure – Exposure adjustments affects OverExposure display, in this case only
those areas that are overexposed (clipped) in the RAW file itself will be shown as the overexposed
areas (obviously, the exposure adjustment in
FastRawViewer has no effect on the content of RAW
files).
Viewing the underexposure zone can be turned on and off through Menu–View–Underexposure
Display (or by pressing the U key on the keyboard):
Like in the previous, the underexposed pixels are spotlighted with saturated colors:

Blue – where the blue channel is underexposed.

Red – where the red channel is underexposed.

Green – where the green channel is underexposed.

Magenta – where both red and blue channels are underexposed.

Cyan – where both green and blue channels are underexposed.

Yellow – where both green and red channels are underexposed.

White – where all three channels are underexposed.
