The Heliopan 30mm #8 Medium Yellow Filter for Photographyis a basic contrast filter, primarily for use with black and white film, that slightly darkens skies, helps to cut through haze, and improves overall contrast. It is the most common contrast filter for black and white photography, producing an accurate tonal range and compensating for the blue sensitivity of panchromatic film. There is a 2.5-3x filter factor with this filter, requiring an increase of 1.3 to 1.5 stops for normal exposure.

The front and rear surfaces of the filter both feature a single anti-reflection coating. Each coating helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, they offer protection to the filter substrate while helping to keep the glass clean for longer than uncoated glass.

This Heliopan filter is constructed from Schott glass for increased optical clarity and color fidelity. It features a brass filter ring for durability as well as jamming prevention.
