Formatt Hitech 4x5" 1.5mm Light Balancing Kit with 81A, 81D, 82A, 82C Filters

The Formatt Hitech 4 x 4" Light Balancing Kit with 4 filters: 81a, 81d, 82a, 82c. The 81a: Light Amber / Yellowish filter with conversion 3400-3200k, exposure +1/3. Warms up the look by reducing the blue cast. This filter is used for more subtle changes in color balance and is often known as a light balancing filter (rather than a conversion filter), as it shifts the color temperature in smaller degrees to balance the color of the light to the color sensitivity of the film.

The 81d: Light Amber / Yellowish filter with conversion 3700-3200k, exposure +2/3. This light amber/yellowish filter will make the appearance warmer.

82a: Light Blue filter with conversion 3000-3200k, exposure +1/3. This filter cools lighting situations, but not as dramatically as the 80 series. This light blue filter will make the appearance cooler.

The 82c: Light Blue filter with conversion 2800-3200k, exposure +2/3. This filter cools lighting situations, but not as dramatically as the 80 series. This light blue filter will make the appearance cooler.
