Control contrast. Higher values are recommended for scenes that include both sunlight and deep shade or for increased contrast with such subjects as sunlight on water, brightly-lit autumn leaves, portraits taken against a blue sky, and white objects or people wearing white; note, however, that mottling may appear in pictures taken at higher values. If AUTO is selected, the camera will automatically select values between 100% and 200% in response to shooting conditions.
Increase contrast when shooting indoors or under overcast skies.
Reduce loss of detail in highlights and shadows when photographing high-contrast scenes.
If AUTO is selected, shutter speed and aperture will be displayed when the shutter button is pressed halfway.
200% is available at sensitivities of ISO 400 and above, 400% at sensitivities of ISO 800 and above.
