Q: 1. 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!

A: 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

Q: 10. Using flash outdoors (flash dialled 1 stop brighter than sun), id like to reduce the blue saturation of the ambient daylight (in a colour image, not B&W) will this filter reduce/mute/gray the blue saturation? If anyone has tried this, can you please direct me to an example image? Thanks everyone!

A: Colored filters are usually meant to be used to change the contrast in black and white photography. If you were to use a yellow filter while shooting color, the whole picture will have a yellow cast. The best way to reduce the blue saturation would be to either overexpose the sky, or ideally in post production you can under-saturate the blues.
