When everything is shown, little is felt.

Cinema has always been described through movement – of images, of time, of bodies across space. Yet what if its most decisive movement is neither visible nor measurable in the usual sense? What if cinema resides not in what unfolds on-screen but in the relation between what is shown and what is withheld? One might think of the opening passages of Alain Resnais’s Hiroshima mon amour, where images of entwined bodies are overlaid with a voice that insists on forgetting and remembering, the disjunction between what is seen and what is said generating a third, unstable meaning.
A way into this question can be found in a deceptively simple mathematical structure: the Pythagorean theorem. Conventionally, it resolves a triangle into certainty – a clear relation between sides. But if we suspend its conclusion and attend instead to its condition, something else emerges.
Two sides are given, stable, perceptible. The third – the hypotenuse – exists only because of their relation. It is both dependent and determining, visible in principle yet conceptually different: a line that cannot exist without tension.
To think cinema through this structure is to shift its center of gravity. Image and sound, for instance, can be understood as the two sides – orthogonal, structuring the field of perception. But what connects them is not reducible to either. Between what is seen and what is heard, something is constructed: an interval, an inference, a line the spectator draws without ever fully possessing it. This interval becomes almost tangible in Ingmar Bergman’s Persona (1966), where the merging and splitting of faces, combined with ruptures in sound and silence, produce an identity that exists only between the elements, never fully in either.

The image alone does not complete meaning; nor does sound. Their conjunction produces a third term – not an addition but a transformation. The spectator is compelled to navigate this diagonal, to traverse a space that is neither purely visual nor purely auditory. It is a space of relation, of tension, of emergence. In Wong Kar-wai’s In the Mood for Love (2000), this space is shaped through repetition – glances in narrow corridors, deferred encounters, and music that returns without resolution – so that the relationship is constructed almost entirely in what the film withholds.

This has consequences for how we understand montage. Often described as the assembly of shots into sequence, montage might instead be considered the creation of distances. Each cut does not merely connect; it separates. It introduces a gap that demands negotiation. Meaning arises not from continuity but from the friction between fragments. The more precise the cut, the more acute the interval. The Odessa Steps sequence in Sergei Eisenstein’s Battleship Potemkin (1925) demonstrates this with striking clarity: the juxtaposition of the marching soldiers, the fleeing crowd, and the falling pram produces meaning not contained in any single image but in the violent collision between them.
Duration, too, can be reconsidered. A long take is typically associated with immersion or realism, but it also produces a different kind of tension. As time extends, the spectator becomes increasingly aware of what lies beyond the frame, of what is not being shown, of what refuses to enter the image. The longer the shot, the more pronounced the absence. In Andrei Tarkovsky’s Stalker (1979), the prolonged tracking shots through the Zone slow perception to such a degree that attention shifts toward the off-screen and the unseen, making absence itself a palpable presence.

The frame itself is not a neutral boundary; it is a limit that implies an outside. Every image carries with it the trace of what it excludes. This exclusion is not a lack but an active force. It shapes perception by directing attention toward what cannot be seen. The unseen is not empty – it is charged, structured, operative. This charged off-screen space becomes the central tension in Michael Haneke’s Cache (2005), where static, surveillance-like frames conceal as much as they reveal, forcing the viewer to confront what remains just outside visibility.

Within this geometry, color can function not as decoration or symbolism but as disruption. Consider the appearance of red. In many contexts, red is quickly translated into meaning – danger, passion, violence. But such readings stabilize what is, in fact, unstable. When red enters a frame, it often does so with a force that exceeds its symbolic function. It interrupts the equilibrium. It draws attention not just to itself but to the conditions of visibility. In Bergman’s Cries and Whispers (1972), the saturated red interiors do not merely signify emotion but engulf the characters, collapsing psychological and spatial boundaries into a single overwhelming field.

Red can fracture the relation between elements. It can pull the eye away from narrative progression and toward a different register of perception. It does not simply signify; it insists. It resists being absorbed into the image’s logic, creating instead a moment of rupture – an event that cannot be fully integrated. A comparable rupture occurs in Dario Argento’s Suspiria (1977), where hyper-saturated colors detach the image from realism, creating a sensory experience that destabilizes narrative coherence.

If the triangle offers a structure, then such interruptions threaten to deform it. The balance between sides is disturbed. The diagonal becomes unstable. And yet it is precisely in this instability that cinema finds new possibilities. When equilibrium is broken, perception is forced to reconfigure itself.
This suggests that cinema is not a fixed system but a shifting geometry – one that is continuously recalculated in the act of viewing. The spectator is not a passive recipient but an active participant in this calculation. Each image, each cut, each sound demands a reorientation, a new tracing of relations.
What emerges is a conception of cinema that prioritizes relation over representation. Rather than asking what an image shows, we might ask what it does – how it positions us, how it directs attention, how it creates distances. The visible becomes only one term in a larger system that includes the invisible, the inaudible, the withheld.
This has particular resonance in modes of perception that do not align with seamless continuity. When experience is fragmented – when images arrive as discontinuous intensities rather than coherent flows – the emphasis on relation becomes crucial. Meaning is not given in advance; it must be constructed across gaps, inferred through partial connections. The fractured temporality of Resnais’s Last Year at Marienbad (1961) – with its repetitions, contradictions, and spatial ambiguities – extends this logic, making perception itself an act of reconstruction.
Last Year at Marienbad
Cinema, in this sense, has the capacity to articulate such experiences. Not by smoothing them into coherence but by embracing their discontinuity. The geometry of relations allows for a form of expression that does not depend on linear progression or complete visibility. It allows for a cinema of intervals.
In an age where images proliferate endlessly, where visibility is often equated with clarity and access, there is a tendency to equate more with better: more information, more explanation, more presence. But this accumulation can flatten perception. When everything is shown, little is felt.
Against this excess, the logic of the unseen offers a counterpoint. It suggests that what is withheld is not a deficit but a condition of intensity. The gap, the interval, the diagonal – these are not absences to be filled but spaces to be inhabited.
To think cinema as geometry is not to reduce it to abstraction but to recognize the structures that underlie its operations. These structures are not rigid; they are dynamic, contingent, responsive. They shift with each viewing, each context, each spectator.
The most decisive line in this geometry is the one that cannot be directly seen. It is traced in the act of perception, in the movement between elements, in the tension that holds them together. It is where cinema happens – not on the screen but in the space it opens.
And it is in this space – unstable, invisible, irreducible – that the moving image continues to find its force.
