There are dozens of websites discussing white balance. There are so many products out there to help correct white balance, but which one to choose? After reading several reviews, I finally decided to test two of the most popular gray cards; WhiBal G6 Pocket Kit from www.rawworkflow.com and Premium Digital Grey Kard from www.digitalimageflow.com.
WhiBal G6 Pocket Kit cost me $29.95 (no shipping cost to The Netherlands). The kit includes WhiBal Pocket Gray Card, quick-release lanyard, table stand, and lightweight carry case. The card is made of extruded cellular PVC; a sturdy foam-like material. It is slightly thinner than a CompactFlash card and about the size of a business card.
Premium Digital Grey Kard is $ 20.99. However, it cost me $22.98 with the shipping. The package includes set of three color balance cards (grey, white, black) and lanyard with detachable clip and safety release. The cards are made of PVC plastic, each the size of a credit card. (more…)
