How can I configure a profile to use the linear tone curve that is associated with a raw file?
I would like to create profiles for my cameras that have a true linear tone curve. i.e. no embedded adjustments for highlights and shadows from the straight line that is characteristic of a raw file linear tone curve.
When I made camera profiles with the DNG Profile editor there was an option for a linear tone curve along with the Adobe standard tone curve.
When testing the profile creation capabilities of the new version of LR and ACR it seems that there is some "below the surface" adjustments made to the linear tone curve. i.e. pulling down highlights via slider or decreasing shadow density via the slide does add more detail to the highlights and shadows. This suggests that there are adjustments baked into the software that deviate from a straight line tone curve.
So, A) are there deviations? B) if so, how can they be removed?
Thanks,

content of dcp profiles can be examined (and modified) using dcptool ( dcptool.sourceforge.net )

I paid a lot of money for the cameras and I'd prefer to be the one making choices about tonality rather than an engineer at Adobe.
My workflow is built around Lightroom and Photoshop for a number of reasons. So don't really want to use a specialized raw converter. I prefer the parametric approach that LR uses offering multiple processing treatments of the same base file.
