Ilah, Glad you brought this up because that's exactly one my current "pet projects". My code is not finished yet but basically, I'm going to be sweeping the entire "1024" scale with my instrument, to determine, exactly, what is what.

So if (ugh that be hard) you're going to use your 16 million color test file, what's going to happen if it's in Adobe RGB vs. sRGB vs. ProPhoto RGB vs. the gamut and calibration of your display? Andrew Rodney http://www.digitaldog.net/ <http://www.digitaldog.net/>
