Heliopan 730509 Overview

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.

question

Hi. Can this filter be used in combination with IR sensitive film (like Rollei Infrared or Ilford sfx)? I see that some filters are described as particularly useful for infrared photography, but not this one. It seems to be the only 30.5 mm dark red filter in stock though, so thought I might as well ask. Thanks in advance!
Asked by: Tine Valentin O.
Infrared film, if shot without filters, looks like normal black & white film. That is because regular light overpowers the IR. So you need filters that are IR friendly. In this instance, you could use this Heliopan 30.5mm #29 Dark Red Filter with Ilford. According to Ilford, When used with a deep red filter, SFX 200 renders blue skies almost black and green vegetation almost white to create a stunning infra-red look to your shots. However, according to Rollei: Please Note: To achieve strong Infrared (IR) effects we recommend exposing the film at a maximum of ISO 25 and using an R72 dark red infrared filter or deeper infrared filter. Standard Red 25A filters are not recommended. Individualized exposure testing is necessary to realize optimal results. Here is the R72 IR by LEE Filters 4 x 4 Infrared (87C) Polyester Filter B&H # LE87C44 which is a gel, not glass or resin. You cut and tape it to the lens. Here is a list of all 30.5mm IR filters we have. https://bhpho.to/2mo9aYU. Here is a site that lists other possible filters for IR film. https://bit.ly/2LjLwYb
