About WhiBal G7

The WhiBal WB7-SC G7 White Balance Studio Card is an extremely accurate, convenient gray card that can hang on a studio hook or lanyard (not included) and can be used in any shooting situation. It can also be used to set neutral White and Black reference areas for setting dynamic range in digital capture using the Black and White Eyedroppers available within Lightroom and other RAW conversion software, Photoshop and most other editing software.

By photographing a gray card reference for each lighting situation, you'll be able to achieve a proper white balance for all of your pictures. The gray card reference picture can be used with software to balance the color casts that various lighting conditions produce with all digital cameras.

WhiBal G7 Features

  • Spectrally neutral - reflects all colors through the spectrum equally. The G7 Reference Card has both a and b Lab channel values of less than 1 at D50 and are spectrally "flat". It's spec'd at less than +/- 0.5
  • Maintains its spectral neutrality under all reasonable temperature and environmental conditions
  • Rugged - waterproof and scratchproof (color goes all the way through, not just a coating on top)
  • Does not respond to UV light any differently than the visible spectrum
  • Each card is individually measured with a precision spectrophotometer to certify that it meets or exceeds stringent specifications
  • Designed for low reflectivity, except that the sticker is intentionally highly reflective so that maximum TrueBlack Blackpoint level may be achieved by observing for maximum glare point
  • Can be used to set white balance reference, Black point and White point

Excellent and Convenient to use


Very compact and clips to camera strap. perfect to get white balance every time. Just place it on the ground and shoot a picture of it. Waterproof, virtually indestructible.


Just what I wanted


Handy to have, easy to carry around.


Good for post production


No support from WhiBal. White balance setting is hit and miss. May be the G6 is the one to get until there is instruction on how to use the G7.


Should probably use it even more.


Indispensable if using the HiTech ProStop filter for long exposures. It makes eliminating color cast as easy as one click. Works so well I should probably use it under other conditions, too.


Must Have Item in your Bag


Helps may my pics look great every time.
