Re: Do you like copying old masters?
Style or substance, yes. Painting as a whole, no.
I have never liked copying, even redoing my own work. There is no important judgement made here. Just a personal preference.
I certainly have pored over old and new masters, the work of many others, to learn. Not only do I consider that helpful, I consider it one of the essentials of learning an art.
That was the way of learning of many schools in the West and the Eastern cultures. Lord knows how many of your or my favorites did so, not just to learn initially, but throughout their careers. I love Van Gogh, for one, and his re-interpretations of Millet are brilliant and are an homage to the latter as well.
But you are unlikely to find me doing it.
