The Nisha 62mm Yellow Filter can be used to increase image contrast when photographing using a film camera system with black-and-white film installed.
When using this filter, wavelengths of visible light that are apparent as violet and blue colors to the human eye are suppressed, while visible light associated with green, yellow, orange, and red colors are able to more easily pass though the Nisha 62mm Yellow Filter and into the lens it is mounted in front of. When photographing with this filter along with black-and-white film, violet to blue-colored subjects within a scene are reproduced in darker shades of gray than without a filter. Simultaneously, green, yellow, orange, and red subjects are rendered in lighter shades of gray than if a filter was not used.
When applied to black-and-white photography, the increased contrast provided by the Nisha 62mm Yellow Filter can result in darker skies with more effectively defined clouds. Shades of green among foliage can be better differentiated, while tans are lightened and the appearance of skin blemishes reduced. Additionally, this filter can minimize the presence of haze caused by the bluish cast of daylight.
