Camera gamut outside horseshoe?

Here’s my blue story, apologies if already posted.

First, with dcraw processing:


Yuck.

Next, with the Adobe Standard DCP for my camera, converted to an ICC with dcamprof:


Better, but still yuck.

Now, with my sunlight_calibrated camera profile, modified per the discussion at: LUDD - Homepage closed


Note the blue has desaturated a bit, but it no longer ‘glops’. Also, note the letters, they’re now greener.

I didn’t use the dcamprof -y parameter; instead, I converted my profile from ICC to dcamprof JSON, opened the JSON file in an editor and changed the blue Y value by hand, then turned the JSON back into ICC with dcamprof makeicc. This is not where I want to end up, so there’s more experimenting in the works…
