Final pieces of finished work

Week 12: Faceial Expression

The face is covered by muscles. They have many functions. Most widely known reasons for using them is eating and to create a facial expression, which is one of the main transmitters of the body language. The body position as a language has deeper meaning when it's combined with the specific contraction of face muscle groups.
Each expression conveys a feeling, which is accepted as non-verbal way of communication.
The difference between the face on the elft and the one to the right is the openness of the mouth and the position of the eyebrows. In combination these produce labeled expression as joy and surprise.
Extremely important role plays the angle and the direction of the light that is pointed towards the face. In situations, only by changing the angle of the light can alter the expression.

Week 11: Facial Anatomy - portrait

The face is captured on paper for its superiority in "beauty". Under the skin, there are layers of muscles and organs that define the features of a person.
A portrait is planned carefully, because every detail is extremely important for the correct representation. The thickness of the cheek muscles give a certain look. The muscles around the mouth can cast additional shadow if highlighted from a side. The eyelids cover the eyeballs, which makes the eye appear from open to closed.
As a basic study of the structure of the face, stronger shadows are being produced by the nose, the inner part of the eyelids that is close to the base of the nose, the chin, the cheeks and the skin under the head that covers the neck.
The face is mainly expressed by the saturation of the shadow cast by the muscles and the shape of the skull.

Week 10: Tone and colour in skin

As human skin is semi-transparent in nature, it consists of multiple changing colours. The blood is major factor for the base tone value. Regarding of the condition and the blood flow in an area, the place can change from pale pink to purple blue. The fat gives slightly yellow addition tot he mixture of red, blue and green, produced by the different type of veins and their density.
The colour study applies the basics of producing realistic skin values by combining of basic colours.

The light on both pictures is dimmed, due tot he time of the year. This provides the slight brighter effect when it reflects from the skin of the model. By nature, the overal gamma of the body is in the more yellow spectrum than any other. That is why base colours of yellow to orange and blue to green are mixed. The reflected colours from the drapery on the chair also mix with the skin colours.
Shadows are expressed as darker mixture of blue and red  and a little bit of green. As the main colour of the paper is white, the RGB gamma is suitable to produce harder and darker combination needed for the shadows.
