This Hoya Red #25A filter is ideal for strong contrast improvement since it absorbs green and blue completely and enhances red. In addition to contrast control, red filters enhance skin tones, tonal corrections and are effective for more dramatic landscapes.
Multicoated to minimize reflection at the filter surfaces which reduces flare and ghosting.

Comments about Hoya 52mm Red #25A (HMC) Multi-Coated Glass Filter for Black & White Film:
Red filter makes for dark skies in B&W, greatly enhancing the drama and contrast of puffy white clouds. The problem is the red filter costs 2+ f-stops in aperture or shutter speed.

Comments about Hoya 52mm Red #25A (HMC) Multi-Coated Glass Filter for Black & White Film:
I shoot large format B&W exclusively and use this on my Nikkor-M 300mm. Good filter for more extreme sky & cloud intensification. High optical quality at a reasonable price. Can't think of any shortcomings. I like Hoya and use their filter products on all of my lenses.
