QP Card QP Color Reference Card 202

The QP Color Reference Card 202 from QPcard is a color reference card that offers a simple way to get accurate and sufficiently saturated colors from your digital camera. QPcard 202 has 35 coated color chips mounted on a 240 x 170 mm cardboard surface. The carefully selected color samples are individually mixed in order to achieve as straight-forward spectral response as possible. This is very important in order to avoid undesired metameric effects that can ruin correct evaluation of the color performance.

The colors on the QPcard 202 are divided into four groups. The primary group has 9 saturated samples of red, green and blue chosen to determine the spectral midpoints of the on-sensor filters. The secondary group has 12 samples of complementary colors chosen to properly graduate saturated colors. The grayscale group has 7 neutral samples of different lightness for white balancing and linearization of individual channel response. The pastel group with 7 lighter, still saturated, color samples helps fine-tuning skin tones and lighter colors.

The QPcard 202 is best utilized with the included QPcalibration software. QPcalibration compares the camera's color performance with the target colors on the card and creates instructions to organize the new color profile. Simply take a picture of QPcard 202 in RAW mode, open the picture in QPcalibration, calculate a profile, give it a name and save. The profile will be saved and can immediately be used in Adobe Camera Raw.
