Tiffen 62mm 25 Red Filter video accessory

Medium Red Filter for Black-and-White Photography

The Tiffen 25 Red Filter is a 62mm screw-on glass filter built for photographers shooting black-and-white film or digital. It darkens blue skies to create strong contrast with clouds and separates foliage from flowers for clearer tonal definition. The filter factor is 8, requiring a three-stop exposure increase to compensate. Infrared film users gain extreme sky contrast and white foliage rendering.

Behaviour Under Sustained Use

Optical performance remains consistent across long shooting sessions because the ColorCore laminate is sealed between two pieces of optical glass. The solid glass construction resists heat buildup from continuous sunlight exposure without shifting density or hue. No moving parts or electronics are present, so reliability does not degrade with time. The metal mounting ring maintains precise thread alignment after repeated attachment and removal.

Thermals, Noise and Power Draw

The accessory is completely passive, drawing no power and producing no audible noise during operation. Glass and metal components dissipate ambient heat naturally without requiring active cooling. Surface temperature tracks the surrounding environment, so handling comfort is unaffected by extended use. There are no fans, motors or electronic circuits to generate heat or sound.
