Without (top) and with (bottom) WhiBal White Balance correction in RawShooter

Having a "GrayCard" 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 it, hence blue-ish in Daylight and Orange-ish in incandescent lighting. By photographing a Gray Card reference for each lighting situation that you are in, you are assured of being able to achieve a proper White Balance for all of your pictures.The Gray Card 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 and RawShooter 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, as above. Remember that the most accurate Gray Card 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 Gray. This means that they reflect all colors through the spectrum equally.
  The Gray Cards within the WhiBal™ system have both *a and *b Lab channel values of less than 1 at D50 and are spectrally "flat". The WhiBal RAW Gray Card is spec'd at less than +/- 0.5! 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 (color goes all the way through, not just a coating on top). 
  WhiBal™ is.
• It must not respond to UV light any differently than the visible spectrum.
  Whibal™ does not.
• The Gray Luminance value must be in a range that is good for digital cameras.
  WhiBal™ rules!
• Beyond technical specification, the most important aspect of a Gray Card is that you use it. WhiBal™ Pocket is the size of a US business card (2x3.5 inches) so that it fits in your shirt pocket or hangs around your neck with the included Lanyard.
  WhiBal will be used and not be an accessory that lives in your camera bag.

Very simply, WhiBal™ combines all the best features of all available Gray cards and meets or exceeds their technical performance in a unique package that can be used conveniently in all your shooting situations. In addition, WhiBal™ provides convenient neutral White and Black reference areas for setting dynamic range in your digital capture using the Black and White Eyedroppers available within RAWShooter and other RAW conversion software, Photoshop™ and most other editing software.
