and once you have 4-5-6-7-8 pigments that's it...
Same thing I said and think. The main gamut is achieved with the main 4 inks, the rest are for improving details here and there.
all that wide DR & making it glossy to achieve saturation is all snake oil... you have just so many different spectral reflectances ...
I find your sentence bold and a bit agressive to me. Given the thing that you have never seen one of these charts, tested it nor even got access to the reference file, how can you state that?
So many different spectral reflectances? If there are 4 main inks, there are just 4 spectral reflectances. Then there are many mixes.
How many different spectral reflec. does a CC classic have? 24? How many a CC SG? (answer: 140)
But, anyway, I didn't know that many different spectral reflectances suppose a problem for a photography that will be always take under high quality sources, with high CRI: Prophoto, Broncolor...
I really don't get the point. But I detect some refusal. And also poor understanding of what's my chart aimed to, although I've explained clearly: art reproduction, e-commerce...
now if you so inclined to sell snake oil - make it 2 charts: matte and glossy - rawdigger perfectly allows to combine synthetic data from several shots and you don't need to have all patches glossy
I don't sell snake oil, and I won't push my customers to buy and use a software that will make their work much more complicated, thus making them refusing my chart. Is that so hard to understand?
I repeat: it's aimed to photographers, not to scientifics or tech geeks.
