Availability: In stock



The ExpoDisc 2.0 White Balance And Portrait Filter  is a custom white balance filter that allows digital photographers to quickly and easily set an accurate custom white balance. Consistently producing excellent results in natural, artificial, and studio lighting, the versatile ExpoDisc 2.0 even excels in difficult mixed lighting environments.


Use ExpoDisc to Save Time Editing White Balance in Photo and Video

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.

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.

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

Getting great color with the ExpoDisc is easy.  To set a custom white balance with the ExpoDisc, simply place the disc in front of your lens and follow your camera's custom white balance procedure to capture an incident light reading through it.  For most cameras, this procedure takes only about 15 seconds.

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

ExpoDisc 2.0 Includes New Portrait Warming Filters (Gels)

The original ExpoDisc Professional White Balance Filter was available in separate Neutral and Portrait (warming) versions.  ExpoDisc 2.0 combines these versions into a single tool.  ExpoDisc 2.0 includes two levels of custom warming filters (gels) which can be inserted into recesses on the face of the ExpoDisc, allowing photographers to add varying degrees of warmth for pleasing skin tones.

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 and to produce a dust map of the image sensor.

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.  It's also possible to make exposure adjustments based upon the position of the histogram spike on an ExpoDisc test shot.  Simply adjust the aperture, shutter speed, or ISO until the spike is centered.

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.
