The distorting effect of the lens creates an optical illusion, amplifying curves and volumes. Then, perspective, the master of deceptive angles, generates visual distortions, giving the impression of a fuller silhouette. Moreover, lighting and its subtleties play a major role. Light and shadow, by sculpting volume, can accentuate certain roundness. Finally, the psychological impact should not be overlooked. Self-perception, often biased, confronts photographic artifice, exacerbating our critique of our own image. So, rest assured, this altered perception does not reflect reality.
Optical Illusion: The Distorting Effect of the Lens
The art of photography is complex and fascinating, where optical effects play an essential role in creating captivating images. The power of the lens lies not only in its ability to capture the present moment but also in its tendency to distort the world around us, thus creating a unique optical illusion. There are various types of distortions caused by the lens, such as barrel distortion, pincushion distortion, and moustache distortion.

Barrel distortion, often encountered when using wide-angle lenses, makes the center of the image appear bulged. This anchor meticulously printed may, for example, seem curved or inflated like a round balloon instead of being straight when this distortion occurs.
In contrast to the previous distortion mentioned, pincushion distortion is easily identifiable. It creates a concave impression on the central subject captured by your digital or reflex camera. To illustrate this: imagine taking a direct photo of an antique wall clock • while it should appear perfectly circular from your viewpoint • it might look oval due to this phenomenon.

Then comes the one described as rarer • if not exceptional -, namely the variation known as moustache distortion.
Deceptive Angles: When Perspective Plays Tricks
The art of perspective has been widely used by artists to create the illusion of three-dimensional space on a flat surface, but this technique also presents its share of pitfalls. The power of deceptive angles is one of the main challenges faced by those trying to master this complex tool.
Perspective is a true visual game, in which objects are rendered with precision and realism even though they do not actually exist in three dimensions. This is where the first pitfall lies: the human mind clings to what it perceives as “real” and struggles to accept that an image can be anything other than what it seems at first glance.
Next comes the power of deceptive angles. An object can appear completely different depending on the angle from which it is viewed. Think of a straight road that seems to end in a point when you look straight ahead; or a square tower that looks more like a triangle when viewed from its lower tip. These erroneous perceptions can lead our minds to draw incorrect conclusions about the nature of an object or even a given situation.
The other major trap concerns the relative size of objects in perspective: they appear to diminish as they move away from the viewer, creating a convincing but potentially misleading illusion of depth.
Lighting and Its Subtleties: Light, Shadow, and Volume
The role of lighting in shaping a space should not be underestimated. It has the ability to modify not only the ambiance but also the perception of volume and shapes within it. Light, in reality, determines how we perceive the three dimensions: length, width, and height.
Thus, a lamp placed near a wall can visually reduce or increase its size depending on its location and the direction in which it casts its light. Similarly, direct lighting on a specific object will highlight its contours and give it more presence compared to its immediate surroundings.
Therefore, playing with these elements can create dramatic or subtle effects depending on our aesthetic or practical intentions. For example, shadow, which is often seen as the negative counterpart to positive light. Shadow draws our attention to what it conceals just as much as to what it reveals.
This is where the importance of the contrast between shadow and light manifests: it not only enhances our perception of volume • objects seem more three-dimensional when their surface has different shaded areas • but also of the colors themselves • thanks to chiaroscuro.
As for the subtle nuances mentioned earlier, they are essential when seeking to establish a particular atmosphere in a room.
