ECI RGB v2

Lily
  • Updated

This color space is the recommended space in the Metamorfoze Preservation Imaging Guidelines and the only one allowed at the highest level of those imaging standards. This profile is the most likely to produce the same result across different color engines. Although white is not neutral (it has a slight tint at 255, 255, 255), it is the only profile that avoids all the other compatibility issues. ECI RGB v2 has a usefully wide gamut that extends beyond AdobeRGB in certain hues, however, it cannot quite represent saturated blue and magenta hues that sRGB can. Nevertheless, it is particularly suited to modern printers and, with correct exposure, uses bit-depth efficiently, making it one of the most suitable color spaces for 8-bit/channel images.

    The Metamorfoze Preservation Imaging Guidelines (Version 1.0, January 2012), chapter 2.4 "White balance and tonal capture" states:

    In Photoshop the L*a*b* values and the 8 bit pixel values can be measured using the
    eyedropper tool. The minimum setting for the eyedropper tool is 11 x 11 pixels.

    Question: What is the patch size of the Color Readout, and the White Balance color picker in C1?

    The only information I could find is in the release notes v20:

    White Balance Picker re-engineered

    Thanks
