Why do portrait photographers prefer black and white?

Photographers are not satisfied with realistic color photos, while black-and-white photos are more abstract and closer to our definition of "art", because they strip color: they come from life and transcend life.

For photography eager to enter the "art" category, how attractive this attribute of black and white photos is!

Portrait photography has more creative space than other subjects, so masters spare no effort to apply black and white photos with the concept of "art" to portrait photography.
