The Tiffen 67mm 81A Warming Glass Filter is the mildest of the 81 series, boasting a filter factor of 1.4 and requiring just 1/2 f-stop of additional light. This easy-to-use filter is designed to correct color rendition on film, whether you're working with natural or artificial light sources.
The 'filter factor' is a measure of the light absorbed by the filter. Cameras with internal metering will automatically adjust the exposure, while those using external or handheld meters will need to account for this factor.
This warming filter is part of the 81 series, which includes the 81B, 81C, and 81EF filters, each offering varying degrees of warming effect. For photographers seeking a cooling effect or other color corrections, the 82 series, 80 series, 85 series, FL-D (daylight), and FL-B (bulb) filters are also available.
Whether you're a professional photographer or a hobbyist, the Tiffen 67mm 81A Warming Glass Filter is a valuable addition to your photography equipment, designed to enhance your images and create the perfect mood or aesthetic.
