post processing - What is the Lightroom equivalent of setting the contrast to -2 in the camera?

I am playing with the different picture styles directly from my Canon 5D-II and I would like to know if there is some sort of mapping with what I can do in Lightroom.

What is the equivalent of -2 contrast in Lightroom?

What is the equivalent of +1 saturation in Lightroom?

Answer

There is no equivalent. These scales are completely arbitrary and not measured in any unit! There are no step sizes and no real limits, for example:

Some cameras let you go from -2 to +2, -5 to +5, 0 to 9 or even non-numeric scales like high to low.

Note that these parameters are subject to interpretation. For example, there are dozens of ways to sharpen images and software differ in the algorithms they use. Even something like Contrast is not 100% defined and may be done in different spaces.
