To get the best from your digital camera, using a gray card is the most accurate method available for setting white balance.
WhiBal's G7 White Balance Reference Gray Card (7.5x10") is
extremely accurate, convenient gray card that 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.
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".
-
Maintains its spectral neutrality under all reasonable temperature and environmental conditions.
-
Physically 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.
- 7.5x10" (19.05 x 25.4 cm)
