Say goodbye to cumbersome grey cards. With the ExpoDisc v3, the perfect white balance is easier than ever. Simply place it in front of your lens to capture the incident light while adjusting your white balance. It is fast, intuitive and saves valuable time.
Enjoy the flexibility and convenience of ExpoDisc. Take control of your workflow by adjusting the white balance in the camera without the need for additional software. Alternatively, you can capture a grey reference image to optimize your white balance during post-production, and use your preferred image editing software when processing RAW files.
Achieve accurate color balance in the visible spectrum (380nm to 700nm) thanks to the remarkable 0.9% light transmission delta of the ExpoDisc v3 from 380nm to 700nm. Enhance your infrared photography with the excellent light transmission of ExpoDisc v3 in the near infrared spectrum with only 1.1% light transmission delta (700nm to 1600nm).
Take it anywhere. At only 9mm thick, the ExpoDisc v3 is thinner and lighter than its predecessor, making it easier to hold over your lens and conveniently put in your pocket.
For those who prefer direct attachment, the ExpoDisc v3 introduces a newly designed bayonet mount. Simply thread the included step ring onto your lens and quickly turn the ExpoDisc v3 onto the step ring to adjust your white balance.
Calibrated to ANSI standards for digital light meters, the ExpoDisc v3 delivers 14% light transmission and a remarkable 1/3 to 1/2 f/stop improvement in exposure accuracy.
