BarBara Hanlo (b. 1957) is a Dutch visual artist whose practice centers on photography as a material and temporal process. From an early age, she was drawn to light as both subject and medium, approaching photography not simply as a means of representation, but as a way to investigate how the world becomes visible. For Hanlo, photography—literally “drawing with light”—is a method of inquiry that unfolds at the intersection of perception, matter, and time.

Her work consistently explores phenomena that exist between the visible and the barely perceptible. Moving fluidly between figuration and abstraction, Hanlo creates images that register subtle shifts in light intensity, movement, and energy. The camera, in her practice, is not a neutral recording device but an instrument that reveals transformation. Rather than capturing static moments, her photographs emerge through processes that make change itself visible.

A significant part of Hanlo’s artistic development took place in the darkroom, where she treats light as a physical material that can be shaped, delayed, filtered, or obstructed. Here, photography becomes an act of construction rather than documentation. Central to this approach is her use of the photogram, a cameraless technique in which objects are placed directly onto light-sensitive paper. The resulting images do not depict objects in a conventional sense; instead, they record the interaction between light, material, and duration. Edges dissolve into gradients, transparent surfaces reveal varying degrees of light transmission, and movement leaves behind layered traces.

Time plays a crucial role in these works. Exposure, development, and fixation are understood as stages in a process that leaves visible marks within the image. Each photograph embodies its own making, carrying the duration of its formation within its material structure. This attention to process is also evident in early works such as Historiae Aegyptiae, where an image of Nefertiti gradually emerges as its supporting layer dissolves, intertwining personal memory with broader historical narratives of destruction and renewal.

In later series such as Archetypes, Hanlo expands her investigation through iterative processes of drawing and photographic transfer. Simple ink drawings are repeatedly reprinted, generating layered images with a distinct spatial depth. These works resonate with the notion of archetypes as recurring structures within human perception, yet they are realized materially, through accumulation and transformation rather than symbolic representation.

Material experimentation remains central to her practice. Hanlo has developed techniques of chemically altering black-and-white photographs using metal compounds such as iron chloride, producing characteristic blue tonalities that arise from the image itself. Color, in her work, is not applied but generated through chemical reaction, shifting attention from optical perception to material formation.

This inquiry extends into her Color Movements series, where rotating colored forms are captured in long exposures, collapsing motion into circular structures. Using Polaroid technology, which translates spectral light into pigment in real time, Hanlo makes visible the transformation of light into matter. The resulting images evoke both microscopic and cosmic scales, suggesting a continuum between inner and outer worlds.

Throughout her oeuvre, chance operates as an integral force, shaping outcomes alongside deliberate intervention. Hanlo’s work ultimately resists fixed representation, focusing instead on the conditions through which images come into being. Her photography does not merely depict the world, but reveals the processes that allow it to appear.
