WhiBal Certified Neutral Gray Card for White Balance

We designed and manufacture the WhiBal White Balance Reference Card to be the best digital Gray Card available anywhere. Each and every WhiBal Card is individually measured ensurring that each WhiBal card we ship meets or exceeds our stringent specifications.


Having a Gray Card reference is the best assurance that the digital pictures that you capture will have the ability to be properly white balanced. Only with a proper white Balance can you be ensured of proper and accurate color, regardless of lighting conditions.

Unlike your eyes, a digital camera does not automatically see whites as white. It sees the color of the light reflected from the scene, hence bluish in daylight and orangish in incandescent lighting. By photographing the genuine WhiBal reference card in each lighting situation, you are assured of being able to achieve a proper White Balance, with accurate, natural colors and no color cast.

The WhiBal reference picture can be used with today's software to balance the color casts that various lighting conditions produce with all digital cameras. The best method to properly White Balance your digital pictures is by using a Gray Card properly and shooting RAW. RAW Conversion Software such as Adobe Camera Raw, Lightroom, Capture One and Photoshop and can then perfectly adjust all the captures that were shot under the same lighting conditions. And the beauty of the WhiBal® is that it is small enough to fit in your pocket or around your neck, so that it will be used on a regular basis. Remember that even the genuine WhiBal is useless if it sits in your camera bag.

What are the criteria for selecting a good Gray card?

  • It must be spectrally neutral. In other words it must be gray! Not close, but actual perfect gray. This means that it will reflect all colors through the spectrum equally.  WhiBal cards have both *a and *b Lab channel values of 0 (+/-0.5) and are therefore spectrally "flat"!.  And each card is individually measured to certify this spec.
  • It must maintain its spectral neutrality under all reasonable temperature and environmental conditions. WhiBal does.
  • It must be physically rugged. waterproof, scratch proof. WhiBal is (color is below the top surface, not just a coating on top).
  • It must maintain its spectral neutrality under all reasonable temperature and environmental conditions. WhiBal does.
  • The Gray Luminance value must be in a range that is good for digital cameras and not 18%. WhiBal rules!

Beyond technical specifications, the most important aspect of a Gray Card is that you use it. WhiBal® Pocket is the exact size of a US credit card (2x3.4 inches) so that it fits in your shirt pocket or wallet. WhiBal will be used and not just relegated to an accessory that lives in your camera bag.
