Hi,
I am not seriousy in the portrait business. This is actually the one of the two portrait images I have with the P45+.
The reason I posted the question is mainly that I try to find a profile that works well enough, and I am not familiar with skin tones.
I can measure skin tones, but a correct skin tone is not necessarily a pleasant one. I absolutely agree on the need of grey reference but I mostly forget. The default DNG-profile for the P45+ in Lightroom doesn't work well at all on the Sony's it is quite OK so I don't use home made profiles on that one.
I am not really enthusiastic about C1, as it doesn't fit my workflow, but Yair has shown to process that image to look decent.
Best regards
Erik
Erik, I know what the components in Lab are.
The point was, if you want to get serious about portraiture and skintones, it's best to shoot with a grey card and/or color chart and most importantly, develop an eye for this style of photography.
I know quite a few very serious and very famous portrait artists and none of them would be spending time doing any of this measuring stuff. This is one of those instances where the "Art" part needs a wee bit more emphasis than the "Science" part.
