Tiffen 3×4 Inch Black Diffusion FX 1 Optical Filter | 34BDFX1

The Tiffen Black Diffusion FX 1 is a 3 x 4 inch optical filter that delivers light, refined diffusion while maintaining the contrast and rich blacks that give an image its structure.

Where classic diffusion filters can flatten shadows and bloom highlights, the Black Diffusion FX design smooths unwanted texture and fine detail while keeping the image feeling sharp and grounded. Grade 1 provides a gentle, versatile effect suited to everyday narrative, interview, and portrait work. Its standard 3 x 4 inch size drops into professional matte boxes and filter trays.

• Black Diffusion FX filter, grade 1, in 3 x 4 inch format
• Light diffusion that preserves contrast and black density
• Softens skin and fine texture without an obvious glow
• A versatile everyday grade for film and video production
