Spectrum 6
Comparison of spectrum measurements I did with a home made spectroscope processed by ImageJ (as was explained to me on http://www.dpreview.com/forums/post/53041627) with ArgyllPro ColorMeter using an XRite ColorMunki spectrometer. Tungsten and the LED didn't fare too well, but the ImageJ plots of the CFLs weren't too bad.
Note the final image of ColorMeter in Photo meter mode.
