Heliopan

72mm Medium Yellow Filter

Contrast Filter for Black and White Film

Primarily utilised with black and white film, this Heliopan 72mm Medium Yellow Filter functions as a basic contrast filter that helps to darken skies slightly while cutting through haze, and improving the overall contrast. It is commonly used for black and white photography to achieve accurate tonal range and compensate for the blue sensitivity of panchromatic film. Given the 2.5-3x filter factor of this filter, an increase of 1.3 to 1.5 stops is required for normal exposure. The single anti-reflection coating on both the front and rear surfaces of the filter help to reduce reflections, scattered light, and ghosting for improved light transmission and image quality. It also offers protection to the filter substrate while keeping it clean longer than uncoated glass. This filter is constructed from Schott glass for optical clarity and features a brass filter ring to add durability and help prevent jamming. Thanks to the dual threading with 72mm front filter thread, you can combine other filters with this heliopan filter.
