If you have (access to) a color target, you could help out by sending me your daylight + incandescent shots. By doing so, you agree to release them into the public domain under the CC0licence.
This is the reply… so it will be of no use? Thank you.
"This particular item does not come with a reference file. As for as I know, no 24 Colour swatch card does. The software that you use with this item is Adobe Dng. This creates a camera profile your use in photoshop or lightroom.
All supported charts have reference spectra available, and if a chart does not, the owner needs to invest in a spectrometer, e.g. the Colormunki Photo for a mere 500$.

Aside from there not being a program called “Adobe DNG”, that person could be implying that the “Grey White Balance Colour Card” is compatible with the standard Macbeth CC24 spectra, but that is just a guess, this is something up to the buyer to research and up to the seller to make clear, and I won’t be accepting photos taken using a color target I never heard of, of unknown quality, without the required spectra and chart.
Since the profile is cheap, it would be great if someone with a spectrometer bought one, commented on the quality, and uploaded the measured spectra.
