Novoflex Zebra Check Card - 8 x 12 inches - $30 - in
stock
This flexible check card, made of a special polymer, has an
antireflection coating on both sides: one side white, the other grey.
The grey side serves as reference area for exposure metering while
the white side enables correct white balance that is so important in
digital photography. Handling couldn’t be easier. The camera takes
a light reading of either side of the check card to perform an exposure
measurement or white balance and, hey presto, the camera is set optimally
for the prevailing light conditions to guarantee perfect shots.The
Novoflex ZEBRA check card is a must for every quality-conscious photographer,
regardless of the medium used to capture images.

The ExpoDisc is a custom white balance filter that allows digital photographers to quickly and easily set an accurate custom white balance. Consistently producing excellent results in natural, artificial, and studio lighting, the versatile ExpoDisc even excels in difficult mixed lighting environments. The ExpoDisc is far easier to use than any gray card, white card or calibration target. Simply place the ExpoDisc in front of your lens and capture the incident light while setting your camera's custom white balance. Using an ExpoDisc custom white balance will virtually eliminate the need for RAW or JPEG post-capture color adjustments. Also works for video cameras.
