Expodisc 2.0 White Balance Filter - 77mm

Save time editing photos and video with ExpoDisc 2.0. Set custom white balance, meter for exposure and dust map your sensor with the only calibrated and certified 18% transmission incident light metering filter.

ExpoDisk invented the digital white balance filter with the original ExpoDisc and established it as the premium white balance tool by individually testing and certifying every ExpoDisc. Now, ExpoDisc 2.0 introduces an improved mounting design, user-selectable warming filters (gels), and a new lower price-point.

Save Time Editing Photos and Video

The ExpoDisc is far easier to use than any gray card, white card or calibration target. Simply place the ExpoDisc in front of your lens and capture the incident light while setting your camera's custom white balance. Using an ExpoDisc custom white balance will virtually eliminate the need for RAW or JPEG post-capture color adjustments.

Whether shooting in RAW or JPEG, photographers using ExpoDisc to white balance their images save valuable time in photo editing software. When used to set a custom white balance, the ExpoDisc consistently produces excellent color in natural, artificial, and studio lighting, and it even excels in difficult mixed lighting environments.

Attaches Securely to Lenses and Threaded Filters

The ExpoDisc 2.0's filter mount utilizes a button-activated spring design which allows the ExpoDisc to securely attach to equivalent sized lens filter threads, including most low-profile threaded lens filters.

How Do I Set a Custom White Balance with the ExpoDisc?

To set a custom white balance with the ExpoDisc, simply place the disc in front of your lens and capture an incident lighting reading through it while following your camera's custom white balance procedure. For most cameras, this procedure takes only 10-15 seconds.

That's it. No special software, and no post processing required. If you're shooting JPEG you're done. And if you're shooting RAW, simply download your images as shot to save yourself valuable time correcting color.

How does the ExpoDisc work?

Your camera's internal light meter measures the color temperature of light passing through the ExpoDisc to make an "in-camera" color adjustment. This color adjustment is applied to all subsequent images taken using the custom white balance from the selected light reading. Or, if you prefer shooting in RAW file format and batch processing later, simply capture a reference image through the ExpoDisc to use with your image processing software.

Meter for 18% Incident Exposure with the ExpoDisc

The ExpoDisc is not just for white balance, though. The precision calibration and uniformity of the ExpoDisc means that it can also be used to meter for an 18% incident exposure.

To meter for an 18% exposure, stand at the subject's position and aim the camera back towards the intended shooting position. Use the camera's meter as seen through the viewfinder to adjust the aperture, shutter speed, or ISO until a proper exposure is indicated by the viewfinder meter. It's also possible to make exposure adjustments based upon the position of the camera's histogram spike on an ExpoDisc test shot. Simply adjust the camera's aperture, shutter speed, or ISO and reshoot the test shot until the histogram spike is centered.

Dust Map Your Image Sensor with the ExpoDisc

Quickly check your camera sensor for dust, or create a dust map to use later in image editing software. Attach the ExpoDisc to your camera lens, place the camera in Aperture Priority mode, then set the Aperture to f/16. Set the lens in manual focus mode, and set the zoom to 50mm or longer. Aim the camera towards the brightest available light source and click the camera's shutter to capture your dust reference image. Sensor dust can be easily identified as spots on the resulting gray image.

Will the ExpoDisc Work with My Camera?

The ExpoDisc can be used with any digital camera with a custom white balance capability, including all digital SLRs and most point & shoot cameras. The ExpoDisc is compatible with all major camera brands, including: Canon, Nikon, Sony, Fuji, Pentax, Olympus, Samsung, Lumix, and Leica.
