How artists make images appear to be 3D

In soPaintingsme ways artists are very much like magicians, they use ‘tricks, to make us think that a flat surface actually contains a 3 D image. It wasn’t always like that, pre-renaissance before perspective was understood the story of the painting was much more important that how the image was depicted. If you look at very early paintings by Duccio and Giotto, around the early 14th century creating depth in a painting was the most important consideration.

The renaissance changed all that, perspective became understood and became very important. Since then the use of perspective has become the standard way of creating 3 dimensions on a flat surface, but in the 19th century Cezanne introduced a different form of perspective.

Cezanne created what is known as ‘Aerial’ perspective. This form of perspective is not based on geometry or line, but colour. Cezanne understood that colour could be used to create depth in a painting. We all know that cool colours recede and warm colours tend to come forward, but that is very crude interpretaion, as it is quite possible for a cool colour to ‘float’ on top of a warm colour. Cezanne taught us that colour relationships are all relative, an orange can look very dominant and bright against a blue, but quite insipid against a yellow.

Look at Cezanne’s many paintings of Mont Sainte-Victoire, notice the great depth in the paintings, but also notice there is no linear perspective. The depth in the paintings is created purely by the use of colour. For a more in-depth explanation have a look at this webpage.

The top image painted around 1400 has not real understanding of traditional perspective. The second painting painted around 1514 uses one point perspective as shown.

The third painting by Cezanne uses no linear perspective but achieves depth in the painting purely by the means of colour – aerial perspectiveStandard perspective is referred to as ‘Linear’ perspective, in other words line and geometry is used to create, on a flat surface, what we see with our eyes, simply that things get smaller the further away they are.
