How to appreciate an oil painting is different from appreciating a photo?

In terms of techniques, the appreciation of oil painting mainly depends on its composition, color matching and detail description.

From the spiritual level, we need to feel the author's thoughts and feelings, painting style and so on.

Of course, these are similar to photographic works. Oil painting can be done with photos, but the biggest difference between painting and photographic photos is two words: brush strokes. Even in surrealist painting, there are thousands of strokes in the picture, from which we can see how a painter's skill is, which is also the charm of oil painting.
