A dual sided gray card designed for digital photography, suitable for both professionals and hobbyists. Key benefits Improves exposure accuracy: grey side is used for exposure correction, helping you achieve consistent brightness across shots. Accurate white balance: white side provides a reference for setting white balance on the camera or in postprocessing. Simple, repeatable workflow: use a reflected light meter reading from the card to standardize exposure and color across scenes. How it works Place the gray card in the scene to be photographed. Orient the card at a defined angle relative to the direction of the incident light. Take a reading with the camera's reflected light meter. Use the reading to ensure consistent exposures across shots. Use the white side for in camera white balance or for post processing white balance to achieve accurate colors. Use scenarios Studio portrait or product shoots: position the card within the lighting setup to calibrate exposure and white balance for skin tones and product colors. Outdoor scenes with changing light: reference the gray card to stabilize exposure and color when light shifts during a session. Multi shot workflows: shoot a sequence with a common gray reference to simplify color matching and white balance in post processing. Compatibility and performance Compatible with standard digital photography workflows that use reflected light metering and white balance settings. Provides a reliable, repeatable reference to improve exposure consistency and color accuracy. Notes The description focuses on the dual functionality of exposure correction and white balance using a single dual sided card. No additional specifications such as size or material are provided here.
