Why ExpoDisc?
We Individually Calibrate Each ExpoDisc for Neutrality
Only a truly neutral white balance tool like the ExpoDisc will produce consistently accurate color balance in your images. Every ExpoDisc is assembled and calibrated in the USA using custom filters to make sure it transmits light evenly across the visible spectrum. Other tools may claim to be neutral, but do they actually take the time to ensure their accuracy?
ExpoDisc Gives Consistently Great White Balance in Only 10-15 Seconds
No special software and no post processing is required.
Smaller and easier to use than gray cards and targets, ExpoDisc fits in a shirt pocket and only requires you to cover the lens to set a custom white balance. This is usually much quicker than placing a gray card or target in your scene and then taking a reflective reading at a distance.
Custom White Balance Gives You Consistently Great Color
Even the best digital cameras struggle with consistently reproducing accurate color. Images shot with incorrect white balance may have unnatural looking red, yellow or blue tints that are time consuming and difficult to correct.
To help photographers cope with this problem, digital camera manufacturers designed their cameras with multiple white balance functions, including Custom White Balance, Automatic White Balance (AWB), and factory Preset color temperature settings.
Unfortunately, Auto White Balance (AWB) often produces inconsistent color results, and the color temperatures assigned to the camera's Preset white balance settings often do not reflect real world lighting conditions.
Using your camera's Custom White Balance function remains the most reliable way to consistently reproduce accurate, balanced color in digital cameras. The custom white balance function eliminates the inconsistencies of AWB and the gross generality of factory Preset color temperatures because it allows the user to calibrate the camera to an exact color temperature at image capture.

Larger ExpoDisc Sizes Can Be Used with Smaller Lenses
As with the original ExpoDisc, a larger ExpoDisc can be used with smaller filter size lenses by simply holding the ExpoDisc over the lens during the white balance procedure.
Note, some smaller lenses may require use of a step up ring. Specifically we have heard feedback from customers that when using an 82mm ExpoDisc over some 72mm lenses, the filter and lens rings do not line up well. In this case a step up ring should resolve the problem.
ExpoDisc is Hand Calibrated in the USA
The ExpoDisc is tested by hand on a transmission spectrophotometer and individually adjusted using custom formulated materials to ensure an 18% total light transmission across the visible spectrum. This neutrality is important because using a non-neutral tool for white balance can actually add undesirable color casts to images. Each ExpoDisc 2.0 includes a quality control card to certify its neutrality.
Customer Testimonial
"When I got home from my engagement session, I uploaded everything and culled right away. I woke up this morning and started "editing"... 15 minutes ago. And, now, I'm done. I keep going back frantically feeling like I'm missing something. Why did it go so fast?? Why don't I have to really edit anything?! I had heard that the ExpoDisc was awesome for nailing perfect while balance, but what I didn't realize is that it also helps to achieve the perfect exposure too! The ExpoDisc is a game-changer for my business, and it was so much easier to use than I thought!", Tina Kraemer, Pure In Art Photography
