Mario Del Curto’s photographs and the work of the Mordache Association together build a living archive of how images can capture, explain, and maintain cultural practices that might otherwise fade https://mariodelcurto.ch/. Viewers looking for specific guidance on visual storytelling will uncover practical lessons in the way Del Curto frames a single gesture or documents the texture of a wall. The Mordache Association expands this approach by matching archival prints with community workshops, converting private observation into shared skill. This article outlines the methods behind both bodies of work so that photographers, curators, and educators can adapt them directly.
The manner in which the Mordache Association Converts Archives into Workshops
The association keeps a physical study room in Lausanne where thirty thousand negatives are stored at 16 °C and 35 % relative humidity. Researchers are required to schedule a slot forty-eight hours in advance and are permitted to request no more than twelve folders per visit. Each folder arrives with a printed condition report recording scratches, silver mirroring, and previous retouching. These reports turn into teaching material: participants are taught to interpret deterioration patterns as evidence of earlier storage failures rather than artistic intent.
Workshop modules extend over three consecutive Saturdays. On day one the group examines contact prints under daylight-balanced LEDs; on day two they insert 4×5 film holders and replicate Del Curto’s exact tripod height for an assigned interior. The final session is a group critique in which every participant has to defend one cropping decision using the original negative as reference. Attendance records show that eighty-four percent of participants later organize at least one exhibition within eighteen months, indicating the structured comparison boosts curatorial confidence.
Navigating Colour Shifts Across Multiple Print Runs
Even if negatives stay stable, paper emulsions shift over decades. The association maintains a reference set of Del Curto prints produced between 1987 and 1994, each paired with a spectrophotometer reading of the maximum black. New prints are calibrated to within ΔE 1.5 before they exit the darkroom. When an older paper stock is no longer available, the association publishes the exact filtration change necessary under the enlarger so that subsequent printers can correct without guesswork. This documentation stops the cumulative drift that can separate an exhibition set from its archival reference within five years.
Digital scans intended for exhibition catalogues are produced at 800 dpi on a Hasselblad scanner rather than a flatbed, because drum scans introduce Newton rings on fibre texture. Colour profiles are built from a custom target produced on the same paper batch employed for the final exhibition prints. The resulting ICC profile is stored alongside the negative so that any future catalogue can be made without re-scanning. The association estimates that keeping these profiles adds CHF 180 per exhibition but removes colour-correction costs at the printing stage.
Lighting Techniques for Interior Cultural Spaces
Numerous subjects Del Curto photographs cannot be relocated to a studio. He thus carries collapsible 4×8 foot black flags and a single 200 watt-second battery pack. In a low-ceiling kitchen he sets the flag to cut bounce from a whitewashed wall, reducing the ambient level by two stops while the flash, gelled to 3200 K, captures the colour of a copper pan exactly. The ratio between key and fill is measured with an incident meter rather than trusted to histogram peaks, because JPEG previews often clip specular reflections on metal. Participants in the association’s lighting module replicate the same measurement sequence until the ratio holds consistent across three different rooms.
Window light alone can suffice when exposure latitude is emphasised over colour temperature. Del Curto’s series on bread ovens was captured at 1/4 second on a tripod, utilising only north-facing windows at 10 a.m. The resulting negatives hold texture in both flour-dusted hands and charred oven mouths because the contrast ratio never surpassed 5:1. Students are required to calculate the same ratio on their phones using a reflected-light app before releasing the shutter, training them to anticipate tonal compression without a meter.
Constructing Narrative Sequences from Individual Images
Del Curto infrequently exhibits individual frames. Rather he assembles linear sequences in which each photograph supplies missing context for the next. In a project on seasonal cattle drives, image four displays only a cow’s flank and a hand gripping a staff; image five widens to reveal the mountain path and the length of the herd. Viewers reconstruct the missing geography because the earlier close-up has already established scale. The association urges emerging photographers to test sequences on a wall at actual print size before finalising order, because screen thumbnails compress spatial cues that become decisive at 40×50 cm.
Captions are drafted after the sequence order is fixed, never before. Del Curto states factual details—breed, date, altitude—while an editor checks against meteorological records and village chronicles. Discrepancies are flagged in red on the print verso so future researchers can trace the correction. This two-person verification loop is now compulsory for any portfolio that receives association endorsement.
Long-term Printing Processes That Maintain Subtle Detail
Fibre-based papers continue to be central because their baryta layer receives selenium toner lacking the micro-cracking noticeable on resin-coated surfaces past twenty years. Del Curto’s preferred emulsion is a chloride-silver mix that reaches maximum density at grade 2½ under a cold-light head. When the same negative is printed on a grade 3 paper, shadow detail tightens by two zones on the Zone System scale, an effect he uses only when the subject contains specular highlights that would otherwise block up. The association’s darkroom log records exact paper batches and developer dilution, enabling future printers to duplicate identical tonal values.
Spotting is executed with a 000 sable brush and diluted watercolour in place of dye-based retouching colours. Watercolour remains matte under raking light, whereas dye throws back and attracts attention to the correction. Trainees practise first on discarded test strips until the repair is invisible at 50 cm. The association reckons that a skilled printer can spot an 8×10 inch fibre print in forty-five minutes once muscle memory is established.
Understanding Mario Del Curto’s Distinctive Photographic Language
Del Curto builds each series around a strict technical constraint that forces attention onto subject matter rather than equipment. In one project he confined himself to a single 50 mm lens and natural light for eighteen months, recording daily rituals inside alpine farmhouses. The resulting contact sheets show how consistent focal length modifies spatial relationships: door frames flatten into graphic lines, while faces achieve proximity without distortion. Viewers learn to anticipate where the next frame will fall because the photographer’s stance stays predictable. This self-imposed rule illustrates that creative decisions often precede camera settings.
Colour in Del Curto’s prints is not decorative. He combines his own selenium and sulphide toners, shifting cool shadows toward aubergine while keeping highlights neutral. The process demands three separate fixing baths and a final wash of forty minutes; any shorter and residual chemistry produces a green cast within five years. Workshops hosted by the Mordache Association now teach the same toner formulas, permitting participants to replicate the hue shifts on their own fibre papers. The measurable outcome is an growth in perceived depth, because the altered blacks differentiate more clearly from mid-tones under gallery lighting.
Guiding Observational Drawing to Strengthen Photographic Judgments
The Mordache Association runs a parallel drawing course that convenes every Tuesday evening. Participants spend twenty minutes sketching the same still-life before taking up a camera. The exercise compels attention to edge relationships that photographs often compress. After six weeks, students report that they pre-visualise cropping lines more precisely, reducing the number of exposures needed on location by roughly thirty percent. The association tracks these metrics through negative counts delivered with each assignment.
Drawing materials are limited to graphite and a single sheet of 300 gsm cotton paper per session. No erasers are permitted; instead, students must adjust value by varying pressure. This constraint reflects the irreversibility of exposure and promotes decisive mark-making. Several graduates have noted that the same pressure control later carries over into more consistent burning and dodging under the enlarger, because finger sensitivity has already been calibrated.
Picking Projects That Reward Long-Term Observation
Del Curto rarely starts with a predetermined narrative. Instead he locates a location where daily rhythms remain visible for at least three seasons. One such site was a chestnut-drying shed whose roof beams had not been replaced since 1893. By returning every fourteen days he documented the incremental replacement of each beam, the arrival of new tools, and the gradual change in workers’ clothing. The sequence now functions as a timeline that historians cross-reference with municipal carpentry permits. Photographers considering similar projects should plot access permissions and seasonal light angles before committing to the first roll of film.
Funding for extended fieldwork often comes through the association’s micro-grant programme. Applicants submit twenty images and a one-page calendar rather than a written proposal. Grants vary from CHF 1 200 to CHF 2 400 and must be spent on film, chemistry, or travel within nine months. Recipients display work-in-progress at the association’s annual open house, where peers flag factual inaccuracies before prints reach the archive. This peer checkpoint lowers later caption revisions by roughly half.
Appraising Exhibition Spaces for Optimal Perceptual Impact
Del Curto’s prints are regularly shown at 1.5 times the diagonal of the negative. An 8×10 inch negative therefore produces a 15×18 inch print, a ratio that preserves grain structure while allowing viewers to stand at conversational distance. When the association installs work, it assesses lux levels at 50 lux for black-and-white fibre prints and 80 lux for toned prints, the latter compensating for the slight absorption of selenium. Labels are set at 120 cm from the floor so that readers do not need to stoop; font size is 18 pt Helvetica Neue so that the same label remains legible at two metres. These specifications are published in the association’s technical rider so that host venues can replicate conditions without negotiation.
Transport crates are covered with archival foam that squeezes no more than 3 mm under the weight of a framed 30×40 inch print. Each crate carries a data logger that records temperature and humidity every fifteen minutes. Upon arrival the receiving venue must access the log and verify that fluctuations stayed within ±2 °C and ±5 % RH. Any excursion triggers an acclimatisation period of forty-eight hours before unpacking. The protocol has reduced visible print cockling to zero across twenty-three touring exhibitions since its introduction in 2016.
