When you open your RAW files with Adobe Lightroom, they are dull, and desaturated. With LX100 you have to add at least +25 contrast and +10 saturation to get the "normal" look. Unfortunately red's and blue's are still far from the reference, but the image looks much better.
We worked together with Raymond Ménard to give you calibrated camera profiles for Panasonic LX100. We used ColorChecker Passport in different lightning conditions. There is a plugin for lightroom to use colorchecker. It can set the RAW image colors to the reference.
In different lightning conditions the colors absorbs and reflects different amount of light, that is why calibration could help.
How to use our calibrated profiles:
First, download them from here
After unzip you have to put the .dcp files to the
Windows:
C:\Users\*username*\Appdata\Local\Adobe\CameraRaw\CameraProfiles
MacOSX:
\Users\*username*\Library\Application Support\Adobe\CameraRaw\CameraProfiles
"Appdata" under Windows, and "Library" under MacOSX are hidden folders!
If you cannot finds this folder, launch lightroom, go to perferences, and click on "Show Lightroom Presets Folder", then go to CameraRaw/CameraProfiles
After that, launch Adobe Lightroom, choose a raw image to develop. Please use the whitebalance selector tool (w) on an close natural grey or white area of photo. And fine tune the balance with magenta - cyan slider. Now, at Camera Calibration, where now "Adobe Standard" is set, you can switch between our profiles. Choose the closest one to your measured white balance. For example, yours is 2600K, you can use our 2850K profile, and a colors will be fairly close to the reference level. After that you can warm up or cool down the picture if you want, Manual WB is necessary to determinate which profile will mach your light source's temperature.
Don't forget, these profiles are only for setting the amount of colors according the light source. They are not compensate the white balance.
