Thanks Nick
You are very kindly - try to help me.
I am "photograph - beginer", but it seems to me that problem will be in "camera profile" settings in develope modul in Lr 5.6.
I can see there only "Camera Canon PowewrShot G1X", but not "G1 X Mark II" - in which, optical system is totally DIFFERENT - I will wait for update Lr (probably 5.7 ???)
Onve more thank You very much.
