This grade 1/4 Tiffen Rear Mount Low Contrast Filter for ARRI Signature Primes and Zooms works to lessen contrast across the image by creating a small amount of controlled flare near highlight areas. This enables greater detail to be attained in shadow regions, without affecting the values of highlights, in order to produce lower apparent contrast. This filter is ideal for use during midday and other high contrast lighting situations when it is difficult to control both overexposed highlights and underexposed shadows.
