Product description ExpoDisc v3 Professional White Balance Filter Save time editing photos & video by using the ExpoDisc v3 to quickly set your camera's white balance ExpoDisc v3 Professional White Balance Filter ExpoDisc Saves Time Editing White Balance in Photos and Video Don't Waste Time Correcting Color Correcting the color temperature and tint of an image with poor color can be difficult and time consuming. You can eliminate most of your post-capture color correction by setting an accurate custom white balance in-camera with the ExpoDisc. For most cameras it takes only 15-20 seconds to set your white balance with the ExpoDisc. Consistent and Accurate Color Simply set an in-camera white balance to achieve consistent and accurate color in your photos and video. It's much faster and easier to set a good custom white balance with the ExpoDisc than it is to edit the color of your images or video in post production. Hand Calibrated and Certified in the USA Assembled & Tested in California We assemble, test, and certify every ExpoDisc in California on a transmission spectrophotometer to ensure each one meets our standards for light transmission across the visible and near infrared spectrum (350-2200nm) for standard and IR photography. Certified for Neutrality Each ExpoDisc v3 Professional White Balance Filter includes a quality control card to certify its tested neutrality. Neutrality across the full visible spectrum is important because using a non-neutral tool for white balance can result in poor white balance, and therefore poor color in your images or video. Wide Spectrum White Balance 350-2200nm Accurate White Balance The ExpoDisc v3 enables precise custom white balance adjustment across the visible spectrum with a light transmission delta of just 0.9% from 380-700nm to ensure accurate color reproduction for digital photography and videography. Infrared (IR) photography white balance The ExpoDisc v3 maintains excellent light transmission into the near infrared spectrum with a light transmission delta of just 1.1% from 700-1600nm. Quickly Set White Balance - No Software Required In-Camera White Balance To set your white balance, simply hold the ExpoDisc in front of your lens and follow your camera's instructions to set a custom white balance. The custom white balance procedure varies by camera brand and model, but for most cameras this only takes 15-20 seconds. Aim towards the light source When setting a white balance with the ExpoDisc aim the camera towards the dominant light source (just like you would do when metering the light on a subject with an incident light meter). When shooting RAW If you're shooting RAW, set the in-camera white balance and simply download your images "as shot". Or you can capture a reference "gray frame" image through the ExpoDisc v3 to use later in your image editing software. ExpoDisc Improves White Balance Studio Flash / LED Lights Use the ExpoDisc for off-camera speedlights, studio flash, and LED constant lights modified with soft boxes, photographic umbrellas and diffusers. Outdoor Portrait Use the ExpoDisc for outdoor portraits taken in all lighting conditions, including open shade, cloudy skies, and direct sunlight. Indoor Mixed Lighting Use the ExpoDisc for indoor mixed lighting portraits taken under tungsten, halogen, fluorescent, LED, window light, and other combinations of indoor lighting. Landscape Photography Use the ExpoDisc for landscape photography taken under all natural lighting conditions. Improve your white balance when capturing infrared (IR) photography images Reduce your image and video processing and editing time by setting your white balance in-camera with the ExpoDisc v3 when using IR filters or an IR camera to capture infrared images or video. The ExpoDisc v3 utilizes new diffusion materials that deliver an improved wide spectrum white balance from 300nm-2200nm, enabling consistently accurate white balance results when using IR filters to capture images at 550nm, 590nm, 665nm, 720nm, 850nm, IR Blue, or IR Chrome. Setting your white balance with the ExpoDisc only takes 15-20 seconds on most cameras. Improve your white balance when capturing infrared (IR) photography images Image taken using IR Chrome filter.

Custom White Balance When used to set a custom white balance the ExpoDisc consistently produces excellent color balance in natural, artificial, studio, and mixed light environments. How does it do this? When you set a custom white balance your camera meters the exact color temperature of light passing through the ExpoDisc. Your camera then applies the appropriate color correction adjustment in-camera to correct for the color it meters through the ExpoDisc

• EASIER-TO-USE THAN A GREY CARD: Simply place the ExpoDisc v3 in front of your lens and capture the incident light while setting your white balance.
• QUICKLY SET WHITE BALANCE: Save time by setting your photo or video 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.
• 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 1600nm). With a light transmission delta of only 0.9% from 380nm to 700nm, the ExpoDisc v3 ensures accurate color reproduction in the visible range.
