The WhiBal Generation 6 (G6) RAW Reference Card is a simple-to-use standard for setting white balance in all RAW converters, as well as image editors such as Adobe Photoshop. The light & easy to handle single-card format eliminates a need to fan out reference cards, thereby speeding reference capture.
The WhiBal G6 Reference Card is light Gray, and certified to a recommended Luminance level of L* = ~75, which is optimum for use in RAW converters. The hi-gloss sticker on the corner of the card provides a TrueBlack black patch that has been optimized for a guaranteed Luminance spec of L* < 4. (TrueBlack provides a real black-point reference, as opposed to a diffuse black associated with most other multi-shade reference cards), and the sticker also provides a Whitepoint, integral focus/sharpness target, and handy reference scale in inches and centimeters essential for macro, product and scientific photography. The WhiBal hi-gloss sticker, also provides a visual indication within the viewfinder of the angle of maximum glare. By moving the camera or card from the detected maximum glare point, accuracy of the White Balance reference is properly maintained.
