QPcard 201 x 2

QPcard 201 is a reference card with 27 different colors.

It is designed to be used with the software QPcolorsoft 501 that can be downloaded free on this site. The colors on the card are mixed separately from pigments and extremely fade resistant. Some of the colors are mixed to resemble the spectral response of colors in real life: Light skin (#18), Dark skin (#17), Sky blue (#25) and Forrest (#15). The seven neutral patches (#4?10) all have an almost straight spectral response. In practice this means the QPcard 201 can be used in almost any light condition with almost any camera, without suffering from metamerism.

The card is self-adhesive making it perfect to place on almost any surface in the subject. The size of the card is 142 x 40 mm (5.6 x 1.6 inch).

QPcard RAW package

Calibrate your digital camera for RAW shooting using QPcard 201, Adobe Photoshop and Adobe Camera RAW (ACR).

In ACR there is a tab called "Calibrate". Here you will find sliders for adjustment of Shadow Tint, Red, Green and Blue Hue and Saturation. Using these sliders you can finetune the color reproduction of Adobe Camera RAW converter. However, it is almost impossible to succeed without a reference color target like the QPcard 201.

Finetuning of RAW can be achieved manually or automatically. The manual procedure is described by Bruce Fraser here http://www.creativepro.com/story/feature/21351-1.html

In order to accomplish this with QPcard 201 you need a reference image with RGB values. This image can be downloaded here.

But there is also an automatic way to go. Rags Gardner at http://www.rags-int-inc.com has a Technology department on his site: http://www.rags-int-inc.com/PhotoTechStuff/ with lots of useful information and solutions for digital photographers. Rags has written a Javascript for automatic color calibration with ACR. The script can be downloaded free from Rags site here:

Qpcard 101 v2 is the new improved version of Qpcard 101. It has three patches with perfectly neutral dark gray, mid gray and white colors. The Cie L*a*b values are 35*0*0, 48*0*0 and 95*0*0. The spectral respons of the three colors is almost perfect straight, meaning there will be no problems with metamerism at all. The colors are extremely fade resistant.

Since the white patch is free from fluorescent whitening agents, it is perfect for custom white balance setting of your camera before shooting. There is a millimeter reference scale on the card.
