La digital paint es one of the fashionable techniques for all kinds of illustrations, from what they are for all kinds of video games or even for some of the animated films that swarm the billboard.
To paint portraits, surely these examples given that show the 4 important steps to know the process of painting a portrait through the use of Photoshop will come in handy. Like when drawing by hand, the first thing is to do some very quick strokes that determine the proportions more or less accurate of the face, and then in different phases, we get closer to the middle tones to finally give the last details that make up the final portrait. Digital portrait painting follows the same premises.
Although the first two steps seem like you can stretch one in not making the precise proportions, are more important than they seem, since they are the basis for later being able to define the different parts of a person's face.
It has to be said that it is not easy to take portraits, since although each part of a person's face can be illustrated, you also have to know how to catch him in some notch or characteristic expression that says something about him of importance. Hence, it is possible to differentiate between a good portraitist and one who is not so good.
The good thing about being able to work with digital painting is that through layers you can start over, which is quite difficult if we pass it to a canvas or paper.
