The basic material for learning sketching is the dark shade pencil either 6B or 8B whichever is available and a sketch book. We usually avoid rubbing or use of rubber as much as possible and try to bring out shades with use of pencil only. There are many brands available in India with both 6B and 8B easily available (Faber-Castell, Camlin). No need to go for very costly pencils or import brands.

Sketch a lot! Don't think about the result, just let your hand practice its natural movement. The only advise I can give for good sketching is practice, practice and practice.

The basic steps and lessons of the sketching may not seem interesting or may be boring, but they are the ones that make you perfect for further difficult tasks of sketching and drawing. These basic steps have to be mastered and then only you should move ahead.

The basic of pencils

The pencils are available in varying shades of hardness and softness, ranging from 6H to 9B, where H stands for hardness and B stands for black or softness of the pencils.

Lesson 1 - Box shading

Use a ruler and draw 1.5cm x 5 cm boxes and start shading them from very light to darkest possible in steps as shown below in the figure, this is from the learner's sketch book

Lesson 2 - shade Mixing

Lesson 3 - Graphs

Lesson 4 - Stick drawing

Total height of the body - 7 1/2 times the head or seven and half times unit

Praxiteles’s law - body is equal to 8 head (Units)

width of the body = 2 heads / units

Umbilicus - present int he 4th head / unit

Unit 4 also marks position of the elbow and height of the waist

Hand length = face length

Knee is located in the 6th unit /head or junction of the 6th / 7th Unit

Weight is to be distributed evenly or equally - keep the line of the neck, the hips and the feet aligned

Female body - Narrow shoulders and wider hips

Children -

New born - height is 3 times head - middle of the body at navel

1 year - height 3 1/2 times head

4 years - heigh 5 times head

12 years - height 7 times head - middle of the body above pubic area

In elderly - make nose and ears big as they are the only two parts of the body that do not stop growing even after the adulthood.

2 1/3 heads is the width of the male body

space between the nipples is one head

wrist drops just below the crotch

Elbows at the level of the navel

Knees just above the one fourth of the body line

Shoulders - one sixth of the body line from the top

Scale is the mathematical relationship that exists between the actual dimensions of your model and those of your sculpture / painting / drawing, which represents it.

The scale is defined by two numbers that determine a ratio between the drawing and reality.

The first number (numerator) of the proportion refers to the drawing.

The second number (denominator) of the proportion refers to reality.

SCALE = DRAWING / REALITY; that is, if my scale is E = 1/4, we will interpret that one centimeter of my figure is equivalent to four centimeters of reality.

__TYPES OF SCALES__

Scale is a graphical method that allows us to draw any object larger or smaller than it really is.

There are the following types of scale:

**Reduction scale:** The drawing / sculpture is smaller than reality. It will be necessary when we want to draw or design large objects, such as roads, buildings, stadiums, ships, etc. Can you imagine working with a map the size of a shopping center? On **reduction scales, the first number is less than the second** . Therefore, the scales will take the following possible forms: 1: 2, 1: 3, 2: 3, 1:10, 1: 200, etc.

**Scales of enlargement:** The drawing / sculpture is bigger than reality. We will use them when the object is so small that we need to see it larger in order to understand it. For example, it is used in the design of watches, electronic devices, mechanisms, etc. On magnification scales, the first number is greater than the second. They will look like this: 2: 1, 5: 1, 4: 3, 10: 3.

**Real scales:** It is represented as 1: 1, that is, our model measures exactly what is represented.

**PRACTICAL EXAMPLE**

Imagine that you want to paint a **60cm** human figure on canvas, at what scale would your sculpture be?

The first thing is to know how much a human actually measures and the "ideal standard" measurement for a human is **180cm** , this is very important, you always have to know the actual measurement of the figure you are modeling in order to calculate the scale.

Now you just have to divide the real measurement by the measurement of your sculpture, which is 60cm 180/60

**= 3** So you can say that your sculpture would be at **1: 3 scale**

**Examples of scales in the human figure that are usually used (ideal standard of 180 cm):**

**Scale 1: 1 = 180cm: 1 = 180cm, your painting would be life size.**

**Scale 1: 2 = 180cm: 2 = 90cm**

**Scale 1: 3 = 180cm: 3 = 60cm**

**Scale 1: 5 = 180cm: 5 = 36cm**

**Scale 1: 6 = 180cm: 6 = 30cm**

Well now it's time to calculate all the averages of your canvas of 60 cm or 1: 3 scale and for that we have the canon of 8 heads, essential to work the human figure.

The first and main point is to know **the head size for your 60cm painting figure**

Now, let's go step by step:

**1º Calculate head size: 60cm: 8 = 7.5 cm**

**2º The shoulders measure 2 heads: 7.5 cm x 2 = 15 cm**

**3º The hips measure 1 and ½ heads: 7.5mx 1.5 = 11.25cm**

**4º The legs measure and feet measure 4 and ½ heads: 7.5cm x 4.5 = 33.75cm**

**5th Arms measure and hands measure 3 heads: 7.5cm x 3 = 22.5cm**

Ratio of the head to the the width - is approximately two thirds

Width of the nose is equal to the length of the eye

Width of the head is equal to 5 eyes or eyes are placed after dividing the head width into five parts - middle part is left blank then eyes placed on either side

Length of the lower lip is shorter than upper lip though the thickness of the lower lip is 2/3rd and upper lip is 1/3rd

Contour of the upper lip is called cupids bow because of the resemble to the cupid

Ears are located between the lines of the eyebrows and the base of the nose

Width of the neck is one half of the the height of the head

A virtual line divides the face into two halves called central axis of the face

This line is divided in half (middle) - there is horizontal axis of the eyes.

Human head equals - 3 1/2 times the length of forehead or 3 1/2 units

Top of the head - Natural headline

Starting point of the drawing of the face is the tilt line in the vertical axis

Head = 3 unit wide or 3 fore heads

Distance between the eyes is equal to the width of the one eye

Lips at the line dividing middle of the third part horizontally

Upper line - hair line

Second line - eyes

Third line - Nose

Last line - chin

The mouth is located in the center of the center of the last segment (middle of the third part horizontally)

Distance between the wrist and the knuckles = Knuckles and the tip of the middle finger

Index finger is equal to the ring finger

Little finger is equal to the final joint of the index finger

Length of hand = length of the face

Pelvis & Hips

Lines formed by the shoulder and the hips - horizontally gives the tilt of the body

The tilt of the both of these lines marks the equilibrium of the pose.
