Thanks to all who participated in this discussion. Actually not all ( sorry for not mention clearly at the begaining ) but some photographers trend to make photos like painters. It is their own choice or liking. I was following that last few years. Some are making portraits with same looking wardrobe & lighting style as the painter's did. Some are making landscape with over saturated colors + heavy HDR in post processing just to give look of a painting. Anyone can check that in the web. One can get insparetion or composition ideas from painters work, no problem with that. But to give a painterly look like brush stroke & other techniques looses the essence of a photograph, I think.
I presume in near future, camera software will be able to give us master painter's signature look once you click the shutter button. No need to do it in post processing.
