Unfortunately, Heliopan closed its doors in September 2023.

The Light Red (25) Heliopan Filter is designed to build strong contrast in black and white photography. The filter will make skies look more dramatic and give a tonal difference between foliage and flowers. Infrared images can also be enhanced by the filter, giving a moonlight effect. The colors blue and green are completely absorbed, which will make them darker and increasingly show more contrast. This filter will also cut and remove haze from a black and white image. Exposures should be increased by 3 stops, because of the 8x filter factor.

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.

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