There are phenomena whose importance lies precisely in their discretion. They remain outside the center of our attention, yet they silently sustain the very things that make life possible. Moisture belongs to this category. It is present in the air, in bodies, in the earth, in the walls of a house, in our breath, in the condensation on a window, and across landscapes—yet it rarely becomes the object of our gaze. It operates slowly, infiltrating matter and altering it in ways that are almost always imperceptible. Perhaps for this reason, it offers a fertile model for thinking about other equally invisible structures: memory, care, territory, and the construction of an image.
Lo que la humedad oculta de la luz is born from an exercise in observation. During a residency in Galicia, María José Petersen began walking without a fixed destination, allowing the territory to slowly reveal its own conditions. Moisture constantly alters the landscape; as temperature, rain, or fog shift, planes, ruins, vegetation, reflections, and surfaces appear and disappear. The landscape ceases to be understood as a stable reality and becomes a temporary phenomenon. Wandering thus transforms into a methodology: observing before interpreting, lingering before explaining.
Galicia is the starting point, but it does not stand as an isolated origin. The project is built around three territories in dialogue: Galicia, Mexico City, and Guadalajara. Each occupies a distinct position in the artist's experience: Galicia as a territory discovered and traversed through wandering; Mexico City as the everyday space from which Petersen has built her relationship with water, climate, and landscape; and Guadalajara as a territory of training, origin, and return. A network of displacements, affections, genealogies, and materials is established between these places. Moisture functions as a shared condition between geographies, memories, and bodies: something that moves through places and connects them without erasing their differences.
Rather than studying an atmospheric phenomenon, the exhibition asks what invisible structures allow an image to appear. Moisture is the starting point because—much like the pixels of a digital image or the stitches of an embroidery—it remains almost entirely hidden while supporting everything we see. This concern connects the exhibition's diverse mediums under a single logic of construction.
The paintings, created through glazing, record small everyday occurrences: a puddle, a fogged window, a surface where water has left a trace. They are quiet images that shun any spectacular gesture. Glazing builds light through successive accumulations and shares a slow temporality with moisture: both transform the surface, producing effects that emerge gradually.
The large-scale landscape painting expands upon this observation. While the small works attend to minimal phenomena, the landscape gathers these experiences into an image where the territory stops functioning as a background and becomes a web of relationships between water, light, and time. The painting also functions as an archive: it preserves fragments of observations, journeys, and moments that are subject—like moisture itself—to disappearing, transforming, or reappearing.
In the embroideries, this inquiry shifts toward the minimal unit of the image. Landscape I (River) and the collective pieces Practices (Collective) of a Structure Derived from Color Crossed by Seepages of Light use embroidery as a system of visual construction where each stitch functions as a pixel. The image emerges from repetition and the accumulation of small chromatic choices.
Embroidering implies understanding an image stitch by stitch, allowing the time invested in repetition to simultaneously become time for observation, analysis, and memory. The image does not arise from an immediate gesture, but from a slow practice where thought and action remain inseparable. The stitch is, at once, matter, time, and a unit of information.
In the collective pieces, this logic takes on an affective dimension. The images are crafted by different women who have participated, in various ways, in building the artist's life. The work does not merely represent care; it is produced through relationships of care. Genealogy ceases to appear as a linear narrative and instead materializes as a fabric of collaborations. Each stitch corresponds to a different person, silently participating in the formation of an identity.
The core of the exhibition lies in nine suspended containers. Clay vessels, soda bottles, and "Pepsilindros" are reproduced using materials associated with Guadalajara, Mexico City, and Galicia. Each set corresponds to one of the primary colors of the additive mix (red, green, and blue), and the luminous intensity of each piece depends on the percentage of liquid it was originally designed to hold.
This operation converts a physical property into information: an object's capacity determines a luminous intensity; light produces color; and color participates in the construction of a painting distributed through space. The objects stop being merely containers and become units within a system of relations between matter, information, and perception.
The notion of the container thus runs through the entire exhibition. A stitch contains a unit of information; thousands of stitches contain an image; a vessel contains a certain capacity of water; objects contain relationships of light and color; a painting contains a landscape. The room contains the artworks, and the building contains the room. This succession shifts the practical function of the container toward a structure capable of organizing memory, information, and experience.
At the Museo Cabañas, this final scale takes on a particular dimension. The building is also a container of memory for the artist herself—a place linked to her artistic upbringing and now turned into the space welcoming this research. This return to the Cabañas makes the exhibition space simultaneously a container for the work and part of the experience the work contains.
Rather than autonomous sculptures, the nine objects function as pictorial units, three-dimensional equivalents of the pixel. The installation builds a spatial image through relationships between capacity, moisture, and light. The presence of materials from Guadalajara, Mexico City, and Galicia prevents this system from remaining solely in the realm of abstraction: each material carries its own origin, and each territory actively participates in building the work. It is not simply about representing three places, but about putting them in relation to one another.
The exhibition also proposes a dialogue between two image-making systems: RGB and CMYK. While the containers operate through the additive mixing of light, the embroideries and paintings reference the subtractive logic of pigment and print. Visitors physically occupy the space between both models: between the pixel and the layer, between the digital image and the material image, between the speed of code and the slowness of manual labor.
In this sense, Lo que la humedad oculta de la luz participates in a broad history of painting without being limited by it. The glazes evoke techniques developed by painters like Jan van Eyck and Johannes Vermeer, for whom transparency allowed atmosphere to be built from within the image. Later, J. M. W. Turner would push this exploration toward the dissolution of forms into light and vapor. Petersen, however, shifts our attention from the representation of the atmosphere to the very structures that produce it.
Her research also dialogues with contemporary discussions surrounding expanded painting. Painting is no longer defined by a specific support, but is understood as a system of relationships between matter, light, time, information, and territory. The containers, despite their sculptural presence, function as pictorial units; the embroideries, though built through textile practice, participate equally in the production of images. The installation occupies three-dimensional space, yet it continues to operate from core questions inherent to painting: color, light, surface, composition, and perception.
Perhaps the greatest contribution of Lo que la humedad oculta de la luz lies in widening our understanding of painting. María José does not use it to represent the world, but rather as a methodology for investigating it. To paint means to observe, translate, measure, embroider, classify, walk, compare, record, and wait. It means recognizing that every image is the result of countless processes that remain outside our field of vision.
At the end of the journey, the question posed by the title remains open. What exactly is it that moisture hides from light? The exhibition suggests that what remains hidden does not belong to moisture alone. Also hidden are the stitches that support an embroidery, the pixels that build an image, the layers that produce a color, the everyday gestures that constitute a genealogy, and the networks of care that allow a life to exist.
Like moisture, all of these structures are discrete. They operate slowly, almost always outside our attention. Yet, it is these very structures that allow the world—and the images with which we try to understand it—to appear before us.
