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.
