> Depth of field, bokeh and perspective are things that aren't photographic

They are, though (unless you think I'm saying that relative physical distances literally do not exist outside of photography?). You can say our eyes operate as more sophisticated lenses and are likewise constrained by physics and light, to be sure, but the experience of seeing something is very, very different from viewing that thing in a photograph or film.

With your eyes, you cannot study or capture or examine the blurred areas on the periphery of your vision; photography enables that. Similarly, photography enables the capture and examination and artistic presentation of motion blur. Photography creates that apprehension of the world. Painting from or to mimic that apprehension is, I feel, limiting. Even when your subject is not abstract.

What I'm taking issue with isn't the basic principles of light; it's painting a scene the way a camera captures it, rather than the way a painting can. If you truly don't see any representative differences between the paintings of the 'old masters' and the current paintings-of-or-like-photos to which I'm referring, then I think we're just not on the same page here, or I'm simply doing a poor job of explaining what I mean.
