About Factory Seconds: 

ExpoImaging, Inc. inspects every product before packaging it for sale.  Inevitably, this inspection process yields a handful of units that do not meet our high quality standards due to visual blemishes, cosmetic defects, or other irregularities. 

Factory Seconds may possess minor blemishes, scratches, or other cosmetic defects.  Other than these visual imperfections or irregularities, Factory Seconds are fully functional and come with all supporting documentation.

Factory Second units are available for sale in limited quantities from ExpoImaging.  Factory Seconds are sold as is.  All Factory Seconds are marked at a significant discount.

ExpoDisc v3:

We introduced the first ExpoDisc white balance filter in 2004, and almost 20 years later, it is still the best in the market.  Even so, we're always looking for ways to make it better. The new ExpoDisc v3 is our latest effort at making the fastest, most accurate white balance tool we can.

Improved Wide Spectrum White Balance

The new diffusion materials we incorporated into ExpoDisc v3 perform better across the visible spectrum (380-700nm), providing better white balance results when shooting in cool open shade or very warm light.


The improved performance of the new materials extends beyond the visible spectrum from 700-2200nm (near infrared), and enables use of the ExpoDisc v3 to set white balance when photographing with an IR-sensitive camera.

New Thin Design with Bayonet Mount Step Ring

The new ExpoDisc v3 design is thinner than the ExpoDisc 2.0.  The ExpoDisc v3 can be comfortably held over lenses 82mm or smaller, and it also incorporates a new bayonet mount allowing it to be quickly attached and removed from your lens using the included ExpoDisc v3 bayonet mount step ring. A single bayonet mount step ring size is included with each ExpoDisc in either the 77mm or 82mm size.  The 77mm and 82mm step ring can also be purchased separately here if you want to have both sizes.

Save Time Editing Color

The ExpoDisc can be used to set an in-camera white balance using your camera's custom white balance procedure. This custom white balance will be incorporated into your images if shooting JPEG, or will be added to your RAW images as the 'as-shot' white balance.

This saves a tremendous amount of time editing photos later as every image will have a neutral, measured white balance without having to adjust sliders. Stop fixing your color later with software.

For Photo and Video

ExpoDisc v3 works for both still photography and for video. Use your camera's video white balance procedure to apply a custom white balance to your video. This is a huge time savings since correcting color in video is even more time consuming than for still images.

Exposure Metering

ExpoDisc v3 can also be used for incident exposure metering. ExpoDisc v3's light transmission profile has been adjusted to 14.5% which is consistent with most digital light meters and will provide a more-centered histogram on modern digital cameras.

Calibrated and Certified in USA

We test and certify every ExpoDisc at our California facility to maintain strict quality control standards. The ExpoDisc is tested by hand on a transmission spectrophotometer to ensure its neutrality.  This neutrality is important because using a non-neutral tool for white balance can actually add undesirable color casts to images. Every ExpoDisc v3 includes a quality control card to certify its neutrality.
