The Tiffen 4 x 4" 1/4 Low Contrast filter reduces contrast across the entire image by creating a small amount of controlled flare near highlight areas. This allows more detail to be captured in shadow areas without affecting highlight values, to produce apparently lower contrast. This filter is ideal for use in midday and other high-contrast lighting situations when it is difficult to control both overexposed highlights and underexposed shadows. The 1/4 density offers less contrast adjustment than the 1/2 density, but more than the 1/8 density filter.nnTiffen filters are manufactured using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding it to a tolerance of 1/10,000th of an inch. This filter measures 4 x 4" / 101.6 x 101.6 mm.nnnFeatures:nn- Ideal for use in midday and other high-contrast lighting situations when it is difficult to control both overexposed highlights and underexposed shadows.n- Lower contrast allows more detail to be captured in shadows when exposure is correct.nnnSpecifications:nn- Type: Low contrastn- Size: 4 x 4" / 101.6 x 101.6 mm (0.2" / 4 mm thick)n- Grade: 1/4 densityn- Effect: Reduces contrast and provides more detail in shadow areasn- Construction: ColorCore glass
