I am trying to make pictures look like paintings. I am interested about reaching a similar color grading.
This is an example: link
I'm asking an opinion about what kind of techniques should I use. It is not simply about saturation an vibrance. My opinion is that a more complex color grading process must be applied, but I cannot really get a similar effect.
I am not asking what should I do in PS or LR. Just conceptually, what would need to be done.
