ExpoDisc v3 Professional White Balance Filter (77mm) - Save Time Editing with a Quick and Easy White Balance

ASSEMBLED AND TESTED IN USA: We care about our products - we assemble, test and certify every ExpoDisc in California on our transmission spectrophotometer. DURABLE IMPACT RESISTANT DESIGN: ExpoDisc v3 is made from impact resistant polycoarbonate materials that will not crack or break, even when dropped. QUICKLY SET WHITE BALANCE: Set your white balance in-camera (no software required), or capture a gray reference image to use with your preferred image editing software when processing your RAW files in post production. In most cameras you can set a white balance in 15-20 seconds. EASIER-TO-USE THAN A GRAY CARD: Simply place the ExpoDisc v3 in front of your lens and capture the incident light while setting your camera's white balance. NEW WIDE SPECTRUM WHITE BALANCE: The ExpoDisc v3 enables precise custom white balance adjustment across the visible spectrum (380nm to 700nm) and extends to the infrared spectrum (700nm to 2200nm). INFRARED (IR) WHITE BALANCE: ExpoDisc v3 maintains excellent light transmission from 350nm to 2200nm allowing for consistent white balance when using infrared (IR) filters for infra red photography. CALIBRATED LIGHT TRANSMISSION: The new ExpoDisc v3 is calibrated to be inline with ANSI standards for digital light meters, ensuring approximately 14% light transmission. IMPROVED EXPOSURE ACCURACY: With this calibration, the ExpoDisc v3 offers a notable improvement of approximately 1/3 to 1/2 f/stop when using it for exposure metering on digital cameras. Introducing the ExpoDisc v3 Professional White Balance Filter. Setting white balance has never been easier with our best white balance calibration tool ever.

Each ExpoDisc is assembled, tested, and certified in the USA using our state-of-the-art transmission spectrophotometer. We care about our products.

Say goodbye to cumbersome gray cards. With the ExpoDisc v3, achieving perfect white balance is easier than ever. Simply place it in front of your lens, capturing the incident light while setting your white balance. It's quick, intuitive, and saves you valuable time.

Take advantage of the flexibility and convenience of the ExpoDisc. Take control of your workflow by setting white balance in-camera, with no additional software required. Alternatively, capture a gray reference image to fine-tune your white balance during post-production, leveraging your preferred image editing software when processing RAW files.

Achieve accurate color balance across the visible spectrum (380nm to 700nm) thanks to the ExpoDisc v3's remarkable 0.9% light transmission delta from 380nm to 700nm. Improve your Infra Red (IR) photography with ExpoDisc v3’s excellent light transmission in the near infrared spectrum with just 1.1% light transmission delta (700nm to 1600nm).

Take it anywhere. Measuring at just 9mm thin, the ExpoDisc v3 is thinner and lighter than its predecessor, making it easier to hold over your lens and to slip comfortably into your pocket.

For those who prefer direct attachment, the ExpoDisc v3 introduces a redesigned bayonet mount. Just thread the included step ring onto your lens and quickly twist the ExpoDisc v3 onto the step ring to set your white balance.

Calibrated to meet ANSI standards for digital light meters, the ExpoDisc v3 delivers a 14% light transmission and a notable 1/3 to 1/2 f/stop improvement in exposure accuracy.
