Here’s another filter from Midwest Optics that might be of particular interest to fans of obscure IR false-color styles: The DB940. It is particularly suitable for color palettes with violet, aqua, blue and strange green tones in plants and otherwise natural colors. And no – for all those asking the question -, the filter is not better suited for Aerochrome emulations due to the lower IR transmission.
Since I only have a small diameter filter, the larger tests are still pending, as I lack a suitable lens. But here are a few first impressions. Only from images with plants.
The combo is always DB940 plus a Lee filter. Each photographed with a full spectrum Nikon D40x and the standard 18-55mm lens.
