Some proportions of the head are generally common to all faces and need to be right in a portrait.
The human face has an egg form, so we draw an egg.
Before you do that, draw a grid of squares; 3 squares for the height of the egg and 2 squares for the width.
With these 6 squares we have divided the human face to it's most characteristic parts and we even have a vertical symmetry line through the center of our face drawing.
1. The hair line is 2/3 up from the brow line;
2. The brows and the top of the ears are on the same line (in many cases).
3. The nose base and the ear lobs are also at the same level.
I hate computer drawing, so one ear will do the job. We always hate things we don't master, that's human nature.
That's it, see my dummy!
(don't laugh, I know it's ugly!)
Using the same overall dimensions as before for the height and width of the face (we measure them), we divide the height in 4 equal parts this time .
4. Eye level line (1) - generally is halfway from the top of the head and the chin.
The human head is 5 eyes width in front view.
If we divide the eye level line (1) in five equal parts we can see that:
- the distance between the eyes is the width of one eye (2);
- the nose width is the distance between the inside corner of the eyes or the distance between the eyes (2);
- the neck line starts from the outside corner of the eyes (3);
6.The mouth middle line is at 1/3 of the distance between the nose base and the chin (4);
- the vertical lines starting at the center of the pupils, line up with the corner of the mouth (5);
These are the main thoughts I wanted to share with whoever is interested.
Please, keep in mind that all this is just theory, just the basics, like a template.
Every human face is unique.
Still, when observing your model, while knowing the basics, you just have to discover the differences between the actual features and the "template".
