But renderings of roses in photography always seem a little too well lit thus probably causing the red to clip away any detail that might have otherwise been there. Confronted with this the inclination is to desaturate rather than expose a little to the left.
Shooting RAW is fine but when you bring it into Photoshop you choose a space for it to get translated into. sRGB would be a bad space to choose.

OK, well, the i1Pro is a good idea in this case

it might indeed. sRGB can be punishing for saturated reds.

not sure. I was trying to get a correlation between a "real red" that was measured.
Instead you could simply measure a petal from the rose with the i1 Pro. Then use the Lab value in a Lab document in Photoshop for comparison (Lab document in Photoshop is important)
Is there a reason this isn't on the ColorSync list? I'd like to post it there as well.
