In reading about this (including Rockwell and others who think the difference is much about nothing), I have been experimenting particularly with "intimate landscape" images where you find a large range of greens, using both color schemes. Interestingly, I find Adobe RGB more pleasing with better shadow details, larger range of green tones, and slightly higher contrast. Many pros who print use Adobe as their default as there is larger color gamut and perhaps more detail. SRGB is recommended for consistency of appearance when posting on-line. Using NX-D I have not found a way convert one to the other. Perhaps with other SW? There are options to modify specific color channels using the histogram and sliders. Other than changing color temperature and hue sliders, I am not expert enough to know how to manage color changes except through experimentation.
Whether the differences are apparent enough in large prints is yet to be seen.
Anyone with any experience with Adobe RGB?
