Perspective is a fundamental aspect of drawing and painting, and it involves creating the illusion of three-dimensional space on a two-dimensional surface. This is achieved through various techniques, such as linear perspective, where objects appear to get smaller as they get further away, converging towards a vanishing point. Artists like Filippo Brunelleschi, Leon Battista Alberti, and Leonardo da Vinci have all explored and written about linear perspective, and it has been a key concept in art since the Italian Renaissance. The number of vanishing points can vary, with one-point, two-point, and three-point perspectives each offering unique ways of depicting depth and space. Artists can also play with realistic perspective, as seen in David Hockney's work, to create abstracted or surreal compositions. Perspective is a powerful tool that allows artists to guide the viewer's eye, alter their perception, and convey a sense of depth and distance in their artworks.

Vanishing points
Perspective is about the viewer's point of view, specifically in terms of space. Perspective drawing is about understanding the big picture of your work. The technique of perspective drawing and vanishing points is used to achieve a three-dimensional look.
A vanishing point is a crucial concept in perspective drawing. It is the point on the image plane where two or more parallel lines seem to disappear into the horizon. In other words, it is the point at which these parallel lines converge. The vanishing point is always on the horizon line, also known as the eye level. The horizon line is where the sky and Earth appear to meet, and it is usually covered by obstructions like trees, hills, or buildings. The horizon line is at the viewer's eye level, and it is important to note that the height of the horizon line will shift depending on the viewer's height.
There are different types of perspectives with varying numbers of vanishing points. One-point perspective, also known as one-point perspective, occurs when a set of parallel lines is perpendicular to a picture plane. The vanishing point in this case corresponds to the oculus or "eye point", from which the image should be viewed for correct perspective geometry. In two-point perspective, there are two vanishing points along the horizon line, usually used when the viewer looks at the corner of an object. This type of perspective can be combined with the horizon line to give the viewer a sense of height and depth. Three-point perspective has left and right vanishing points on the horizon and a third vanishing point either below or above the horizon. This results in a bird's-eye vantage point.
Artists use vanishing points in their work to create a sense of depth and to guide the viewer's eye. For example, Hedda Sterne's NY, NY No. X (1948) uses different vanishing points to add to the look of a chaotic, built-up environment, reflecting the hustle and bustle of a big city. In Tristram Hillier's paintings, vanishing points are used to create eerie urban scenes of squares, shadows, and buildings.

Linear perspective
The principles of linear perspective were first described during the Renaissance, although they may have been evident to ancient Greek and Roman artists and architects. Italian Renaissance architect Filippo Brunelleschi is thought to have devised the system around 1415, and it was later documented by architect and writer Leon Battista Alberti in his influential book, "Della Pittura" (On Painting), in 1435. Alberti's book included a set of mathematical rules to help artists achieve a sense of realism in their paintings.
While linear perspective is a useful technique, it is not the only way to represent objects and spaces. For example, when technical information needs to be communicated clearly, isometric projections may be a better choice as they provide a less distorted view. Linear perspective is particularly well-suited for narrative illustration, visual development, and architectural renderings, as it effectively communicates concepts and stories.
There are different types of linear perspective, including one-, two-, and three-point perspectives. One-point perspective uses a single vanishing point, while two-point perspective adds a second vanishing point to the left or right of the first. Three-point perspective is similar to two-point perspective but includes a third vanishing point either above or below the horizon, allowing for a bird's-eye view of the scene.

Aerial perspective
The illusion of depth is created by depicting distant objects as paler, less detailed, and often bluer than objects positioned closer to the viewer. This bluing effect is caused by the scattering of light as it passes through the atmosphere, with shorter-wavelength blue light being scattered more than other wavelengths. As a result, distant objects appear to take on a bluish hue, while bright objects may appear redder due to the scattering and loss of blue light.
Additionally, aerial perspective involves reducing the contrast between objects and their backgrounds as distance increases. This reduction in contrast affects all spatial frequencies, softening the edges and outlines of distant objects and blurring interior details. The effect is enhanced by the presence of moisture and particles in the atmosphere, such as dust, air pollutants, water vapour, and smoke, which further scatter light and reduce contrast.
In conclusion, aerial perspective is a powerful tool used by artists to create a sense of depth and realism in their work, mimicking the visual effects of the atmosphere on distant objects and enhancing the mood and three-dimensionality of their compositions.

One-point perspective
To draw in one-point perspective, you must first define a horizon line. This is the theoretical line to which points on any horizontal plane converge as their distance from the observer increases. The horizon line is at the viewer's eye level, and it is often hidden by walls, buildings, trees, etc. The next step is to place a vanishing point on the horizon line. This is the point to which all the lines of perspective will recede. You can then use orthogonals (receding diagonal lines) to define the form of the objects, extending them towards the singular vanishing point.

Two-point perspective
Perspective in art is about the point of view, or how you look at the world. Perspective drawing is a way to create the illusion of space on a 2D surface. There are six ways to create the illusion of space, and three types of linear perspective: one-point, two-point, and three-point perspective.

Frequently asked questions
Perspective in art refers to how objects and spaces are depicted to create the illusion of depth and distance on a two-dimensional surface. It is about the viewer's point of view and how it changes the perception of the artwork.
There are various types of perspectives used in art, including one-point, two-point, and three-point perspectives. These refer to the number of vanishing points used in the artwork.
To create a one-point perspective, you draw straight lines from each corner of a rectangular surface to its centre, creating a vanishing point. Objects are then drawn with lines converging towards this point, giving the illusion of depth.
A vanishing point is an imaginary point on the horizon line towards which parallel lines appear to converge as they recede into the distance. It is used to create the illusion of three-dimensional space in a two-dimensional artwork.
Artists can manipulate perspective to create different effects. For example, using multiple vanishing points can add a sense of chaos, while atmospheric perspective, which involves making distant objects lighter and less detailed, can create a sense of depth and space.
