Re: I have zero problems
Paintings are three dimensional objects and a photograph rarely does them justice.
Depends on the style. Old masters worked with very thin paint layers, and their works are pretty much 2-dimensional unless viewed with a magnifying glass. Slapping on lots of paint became fashionable only in the 19th century.
Even then, a well-made photographic copy, especial if printed on canvas and framed, is very convincing from some distance.
