This is the largest of the 24ColorCards but is is still a convenient 4x6-inches. It comes
in a Tyvek protective sleeve along with simple, clear instructions for color correction procedures
using Picasa 3.8, Photoshop Elements 9.0, Photoshop Lightroom 3 and Photoshop CS4. In addition,
the 24ColorCard-4x6 has NIST-Traceable color sRGB measurement data printed directly below each
of the CameraTrax 4x6 card.
