The difference between oil painting art and photos

The photo is very simple, you can zoom in and out at will, the time can be completed soon, and you can also digitally modify it later (also called P-picture). Oil painting needs a painter's hand to draw it stroke by stroke (it takes a long time), especially realistic oil painting. In addition to painting time, there are also drying time of oil painting pigments and drying time after polishing. Of course, oil paintings are more interesting than photos.
