Oh, Those Capture One Reds!

I'm getting an Epson 3800, then we'll see...

 

Of course, YMMV :)

 

You'd be better off getting the profile from someone who has a good Lambda printer and checking it against that. Then if the Epson gave you weird results you'd know, at least, it was your fault :)

You have a lambda? :-)

I never trust a distant software engineer to do something I can do for myself. I created my own ACR profile for the M8, shooting a ColorChecker and then adjusting the saturation/hue for R,G,B in ACR's calibrate page until the values of the RGB color patches matched the published values for those patches. The values depend on the color space you use (Adobe 1998 for me), so make sure you use thr right ones. For Adobe 1998, the ColorChecker patches should come out

 

Red - 154R, 51G, 60B

Green - 100R, 149G, 78B

Blue - 55R, 62G, 147B

 

I go back and redo this about every 4 months just in case there is any drift in the sensor.

 

It should be noted, however, that a profile will, at best, make sure that the color relationships are numerically accurate. That has nothing to do with perception. What's right and what "looks right" are two different things.

 

Nor does it cover that fact that the profiling/calibration controls also affect the complementary primaries (C, M, Y).

 

E.G. my profile that accurately reproduces blue hues tends to produce greenish yellows, and correcting the yellows tends to produce cyanish blues, so I profile for the blues and tweak yellows in PS via "Selective Color" or "Hue/Saturation" to twist them a bit towards orange/red. Yellows are a significant part of skin tones, so that tends to improve those, as well.

 

In the original shots of this thread, on MY monitor, the reds are slightly too hot in the first shot and quite a bit too dull and brown/purple in the second. Some may find the second preferable - but that doesn't mean it is correct.

 

On monitor profiling - again, unless one can take one's monitor in to the Bureau of Standards and compare it side-by-side with their "officially" calibrated monitor visually, one really doesn't know how well a calibration device has done its job. It may be warmer or cooler, or have a higher or lower contrast/gamma, than it did before, and it may match prints more predictably, which is good. But it doesn't necessarily mean it meets a universal standard.
