How to take a picture of ink effect? Ink photography? Chinese painting effect?

If you go to Jiangnan water town to shoot in rainy season, a card camera will do. If you have a SLR, you can add a soft lens and adjust the contrast later. I took this effect with a Sony card camera in Suzhou last year.

Maybe other scenery (of course, the theme should reflect mountains and rivers), plus soft mirrors can also be used in rainy days, you can try it.
