Tiffen 7247B 72mm 47B Blue Filter

The Tiffen 72mm 47B Blue Filter is a dark blue contrast filter designed primarily for black and white photography. When placed on your lens, it lightens blue subjects—such as skies and water—while darkening warmer tones like reds and oranges. This selective filtration creates pronounced tonal separation in monochrome images, helping photographers achieve more dramatic skies, better-defined clouds, and richer overall contrast without post-processing.

Constructed from optical glass and manufactured in the United States, the 47B maintains the sharpness and clarity you expect from your lens. At 72mm, it threads directly onto compatible lenses without adapters. While its primary application is black and white work, color photographers can also use it to apply a bold blue wash for creative purposes. The filter's slim profile and light weight make it easy to carry in a filter pouch alongside your other glass, adding a valuable contrast-control option to your kit.
