Tiffen 3×4 Inch Black Diffusion FX 3 Optical Filter | 34BDFX3
The Tiffen Black Diffusion FX 3 is a 3 x 4 inch optical filter delivering a pronounced diffusion effect that still respects the deep blacks and contrast structure of the image.
At grade 3, the softening becomes a clear creative statement, smoothing complexions and diffusing fine detail for dreamier, more stylized visuals, while the Black Diffusion FX architecture keeps shadows dense and halation restrained. Cinematographers reach for this strength in music videos, fashion films, and flashback or fantasy sequences. The standard 3 x 4 inch format works with professional matte boxes and trays.
