Hi,

I tried to convert my RAW files to log in ACR already before the whole RAW video craze but haven't really been successful, hopefully someone that understands that log business a bit better will figure it out...

**If I understand correctly log is derived from linear sensor data, right?** If so, one would have to get the image to linear first and then apply a log curve, right?

Since PV2012 is as far as one can be from anything close to linear I decided to use PV2010 as a starting point because you can get a linear result out of ACR if you do the following (according to

this):

- choose PV2010 in the "camera calibration" tab

- set white balance

- set Blacks, Brightness and Contrast to zero

- choose a linear curve in "curves" tab

- Enable CA removal (optional but recommended)

- set sharpness to Zero (optional)

->Convert back to PV2012 by clicking on the exclamation mark in the lower right corner.

-> save as Preset (optional but highly recommended to save time ;-)

Et voilà we (should) have (almost) linear data that still has the pretty highlight rolloff from PV2012.

If one could explain what a log curve exactly is, that curve could be applied to PV2010 before its gets converted to PV2012.
