Frequently asked questions
What does a Tiffen Hot Mirror do?
It blocks infrared light from reaching the camera sensor. This prevents the magenta color shift often seen in black fabrics and shadows when using heavy ND filters.
Is this the same as an IRND filter?
No. A Hot Mirror specifically targets IR light without reducing visible light, whereas an IRND combines infrared blocking with neutral density light reduction.
Does it fit my matte box?
The Tiffen Hot Mirror is available in standard cinema sizes like 4x4" and 4x5.65", making it compatible with most professional matte boxes from Bright Tangerine, Arri, and Tilta.
Will it make my image soft?
No, Tiffen uses Water White glass which is engineered to maintain extreme sharpness even at 4K, 6K, and 8K resolutions.
