This deep yellow 9 filter tends to overcorrect for rendition of sky, clouds, and foliage in black and white photography with Type B (high red-sensitive) panchromatic materials for more dramatic effect. Designed for Black and White photography, this filter can be used with digital or film. Filters for black and white photography perform a variety of filtration effects including contrast control, enhanced skin tones, tonal corrections and more dramatic landscapes. Although originally intended for use with black and white film, these filters can also be used as a creative tool in color imaging.
