When people are alive, they use sketch heads, which are called sketch heads. When a person dies, the sketch head left behind is called a portrait. Therefore, there is no difference between portraits and ordinary sketches. If we have to say the difference, then professional portrait painters will paint portraits with charcoal powder.

First, draw a character's face on lead drawing paper with a pencil, and then paint charcoal powder on the face with brushes of different hardness and sizes, showing the relationship between light and shade and hierarchy. This will bring the dead back to life, looking just like when they were alive.

Before there was a camera, portraits were all sketched, and some people used oil paintings at different prices, so portrait painters at that time made a lot of money. When cameras became popular, people became accustomed to taking pictures. Many old people will go to the photo studio to prepare their own photos or portraits before they die. At that time, the photos and portraits taken in the photo studio were all black and white, and now the photos are all in color.

However, many old people died suddenly, and portraits were not prepared in advance, or young people, middle-aged people and children died suddenly. Photographers would go to their homes to find photos left by the deceased and deal with them with technology. According to their family, it should be a black and white photo or a sketch photo.

If the deceased didn't leave any photos, he must ask the painter to draw them by hand. According to the wishes of his family, whether it is sketch, oil painting or watercolor, sketch is usually the main one. Just like upstairs said, ask the family of the deceased first, what was the character of the deceased before his death, amiable painting, serious and dignified painting. Anyway, ask the family of the deceased in advance and draw according to the character style.

Nowadays, many young people don't know the difference and relationship between sketch head and portrait.

There are also differences between portraits and photographs.

Portraits are hand-painted black-and-white paintings, and photos are black-and-white photos taken by cameras. Because of advanced technology, many photos can be processed into adult images.

Even now, many traditional places still retain sketches and portraits. They always think it is impolite to take pictures of the dead, which is why portrait painters still exist. Portrait painters are very particular, but portraits are mainly to remember the dead and express their grief. Therefore, when painting portraits, we must pay attention to the true appearance of the face, especially the eyes. Don't be big and small, your eyes should be full of vitality, not dull and colorful.

It is a great thing to paint the dead, and it is also a matter of great merit. Everything should be taken seriously.
