You might try this: http://tinyurl.com/q96yglI'll look into that, thanks. I'm trying out DxO, Raw Therapee, C1, Sony IDC, and Lightroom currently, and while they all certainly render skin tones differently, C1 is WAY off.
Put it in user/library/colorsync/profiles so it will show up as an A900 camera profile in the pulldown menu of C1.
I don't know if that works… I have no file of the A900 and just downloaded some color checker captures of the A900 on imaging-resource.
If you'd like to upload a portrait (raw file) I could make a profile as a starting point for you.
But at least by switching to this profile you should see a color change that is roughly in the right direction… I hope.
