Unfortunately, Heliopan closed its
doors in September 2023. They were the last to manufacture high quality yellow green filters. This is
undoubtedly one of the last opportunities to be able to purchase one of these filters brand new.
The yellow-green (11) Heliopan filter moderately reduces blue tones,
reduces red and brightens green tones. This is a universal filter for
spring and summer landscapes with a lot of foreground, undoubtedly the
most interesting black and white filter for European landscapes. It
corrects the tonal value for the reproduction of different colors when
using conventional panchromatic films in artificial light and also for
portraits and group images in daylight.

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.
