Formatt Hitech BF 43-BW23AORA overview

  • 1Description

Helping to increase contrast when working in black and white, this 43mm Orange 23A Filter from Formatt-Hitech is used to noticeably darken cool and blue tones in order to emphasized both shadows and clouds. Offering greater tonal separation than regular yellow and orange contrast filters, the light-red/orange 23A is especially well-suited to producing dramatic outdoor and landscape imagery. There is an approximate 4x filter factor with this filter, requiring an increase of 2 stops for normal exposure.

This filter is constructed from Schott glass to maintain high image clarity and color fidelity, and it features a lightweight yet durable aluminum filter ring with 43mm front threads.

Orange/light-red filter provides the same effect as a Wratten 23A contrast filter, and helps to darken blue tones while lightening warm orange and red tones, when photographing in black and white.
Commonly used for landscape photography to emphasize and darken blue skies and give clouds more visual depth.
Filter factor of 4 requires approximately 2 stops of additional exposure to maintain normal results.
Constructed from Schott glass for optical clarity.
Aluminum filter ring is both lightweight and durable.

Formatt Hitech BF 43-BW23AORA reviews

43mm Orange 23A Filter is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Excellent filter for increasing contrast Tried this filter on my new 35mm rig, a Zeiss Ikon with a 35 f/2.8 zeiss lens. It was the first test roll for the camera using Tri-X processed at 400 ISO (ASA). I found this to be excellent for B&W landscape and architectural work. You can see a sample of it on my review of the same lens and camera body. What can I say. I'll be getting this filter for the next Zeiss lens and possibly for my Fuji X Pro-1 system lenses.
