The rays emanating from an artificial light diverge equally in all directions. Indeed, we say that they radiate in all directions from the centre of the luminous source.

In the presence of more than one source of light, an object will cast as many shadows as there are luminous sources – which complicates things somewhat since the shadows will overlap more often than not.

This is a real headache for the artist and your drawing can very often suffer as a result.

You will run up against the same sort of problem when daylight enters the same room through several windows.

What is a very pleasant and attractive situation in real life can turn out to be rather less so in a drawing when you strive to render a real effect with a minimum of means by ridding yourself of all but the essential!

So, when lighting an object you want to do draw, I suggest you limit yourself to one source of light for the time being. Once you have completely mastered the basics we are discussing here you can move on to more complex forms of lighting.

Since you are restricted to one source of light for the moment, try if at all possible to choose an angle under which the object is influenced from only one source or, better still, look for a subject which is better suited to this technical constraint.

Before you start drawing your object, ask yourself where you want to position the light. It’s a good idea to place it fairly high up so as to summon up the effect of natural light. This is in fact what artists used to do when they closed up the lower windows of their studios so that light streamed in only from above.

Incidentally, note that in an outdoor scene the lightest part will be the sky whereas indoors the strongest light will bathe the ground.

In addition to its height, the sun can be in many different positions in relation to the subject, and the part in the shade may variously be opposite you (the artist), on one of the sides, or behind the object if its illuminated side is facing the artist.

If the sun is behind you, the subject will be short of shade and if it is in front of you, it will lack light. That’s why a lighting from the side is the most attractive proposition as it affords a whole range of very pleasant nuances. Side lighting allows you to build up a composition in which there is a balanced and subtle interplay of light and shade.

That doesn’t mean, of course, that you can’t create beautiful effects in particular situations such as sunset landscapes where the shadows are turned towards the onlooker, but here the sky takes up a large part of the picture and we would not have the general impression of a lack of light as we would with an object seen against the light.

To sum up, always think carefully about choosing your lighting to your position whenever you cannot alter the illumination of your subject.

There is something else you need to take into account: the direction of the light, or to be more precise, where the light is coming from, the place where it originates.

Whenever the luminous source moves, a shadow changes its shape and position.

A standing figure will cast a short shadow at midday when the sun is high in the sky, and a long one in the evening when it starts to slip below the horizon.inflatable trampoline australia

The higher the source of light the shorter the shadows. In the summer, when the sun is set higher in the sky, the shadows at noon are not as long as they are in winter at the same time. There are even parts of the tropics where the sun is sometimes vertical and a stick set upright in the ground will cast no shadow. But that is an exception. Conversely, the shadows lengthen considerably in the morning and in the evening when the sun is low in the sky.

Objects, lighting and shadow

Objects can receive three kinds of light: sunlight, ordinary daylight and artificial light. Their aspect and that of their shadows will vary depending on which of these lights we see them in.

Generally speaking, the brighter the light the stronger and sharper the shade. This is the case when an object is exposed in full sunlight. If the light is indirect in an overcast sky, the shadows are less distinct and less contrasted, and they tend to disappear completely in diffuse light.

When an object is lit by a single source of light, its sides situated opposite the light are said to be in the shade, whereas we use the term “projected shadow” to define the dark form cast by the illuminated object on the ground or on other interposed objects. This projected shadow is the result of the absence of light at the place where the luminous rays are intercepted by the object.

Shadows take the same form as the objects by which they are cast. For example, a rectilinear figure will cast a rectilinear shadow and a curved object will have a curved shadow. But the shape of the shadow varies according to the form of the surface onto which it is cast.

In sunlight, the source of illumination, that is to say the sun, is so far away and so powerful compared to the objects it illuminates, that the rays of light falling on our planet are supposed by convention to be parallel and this is how they are always treated in daylight scenes (although in fact, as with any luminous source, they “radiate” from the centre of the sun).

The thing to remember, then, is that, in natural light, you should treat the rays as though they were parallel.

The higher the source of light the shorter the shadows. In summer, when the sun is set very high in the sky, the shadows at noon are not as long as they are in winter at the same time. There are even parts of the tropics where the sun is sometimes vertical and a stick set upright in the ground will cast no shadow. But that is an exception. Conversely, the shadows lengthen considerably in the morning and the evening when the sun is low in the sky.

In sunlight, parallel rays will cast parallel shadows which, seen in perspective, will naturally converge towards the same vanishing point.

If the shadow cast by a solid object is intercepted by other objects, for example a fallen tree trunk, a wall or a staircase, it is “carried along” the surface of these objects. The exact form of the shadow will be determined by the points of impact of the rays passing over the perimeter of the illuminated object and continuing towards the object receiving the projected shadow.

This shadow also obeys the laws of optics and will have to be put into perspective in order to give a realistic effect.

Shadow and shade

The three types of light

  1. Sunlight
  2. Ordinary daylight
  3. Artificial light

Sun light and shadows

and shadows at sunrise and sunset are very different than those at midday. When the sun is low on the horizon the shadows will be long, colours of objects will inherit the warm reds, oranges and yellows of the sun. On a clear day objects will have a sharp and dark shadow, however if the weather is overcast, the shadows become less contrasted and the edges are less distinct. The time of day will affect the length of the shadow, in the morning and evening the shadows are long, whilst at midday they are short.

Artifical light

Diffused light, dark, light, effects, contrast, brightness, texture, strokes, lines. When lighting an object you want to do draw, limit yourself to one source of light for the time being. Once you have completely mastered the basics we are discussing here you can move on to more complex forms of lighting.

Contrast

What is contrast ? Contrast is difference between the light and dark areas in a painting or drawing.
