Rogue ExpoImaging white balance filter ExpoDisc V3 82mm (novelty)

The ExpoDisc v3 is an 82 mm white balance filter designed for precise color accuracy in photography and videography. This successor model features an extended spectral sensitivity range of 380 to 2200 nanometers, going beyond visible light to support infrared photography applications. With a slim profile of 9 mm and reduced weight compared to previous versions, the filter maintains portability while enhancing handling. The device allows for the calibration of custom white balance directly in the camera settings by being placed over the lens and configuring the custom white balance function. It operates without additional software and is compatible with most digital cameras and smartphones. Spectral calibration is performed using advanced spectrophotometer equipment to ensure consistent color reproduction under various lighting conditions. The filter has a 14.5 percent transmission calibration that aligns with typical camera metering systems, providing reliable exposure guidance through centered histogram displays. The package includes a bayonet mounting system with an adapter ring for secure attachment to compatible lenses when needed, while hand operation remains the primary method of use. Additional accessories include a storage pouch, neck strap, and certification documentation. Constructed in black and white, this tool addresses color consistency challenges in various lighting environments, including fluorescent, incandescent, and mixed light sources. The extended spectral range and refined design contribute to predictable color results when using presets or processing RAW files, establishing consistent white balance across multiple shooting locations and lighting scenarios.
