Mario Del Curto’s photographs and the work of the Mordache Association together form a living archive of how images can document, interpret, and preserve cultural practices that might otherwise disappear mariodelcurto.ch. Readers looking for concrete guidance on visual storytelling will find useful lessons in the way Del Curto frames a single gesture or documents the texture of a wall. The Mordache Association expands this approach by combining archival prints with community workshops, turning private observation into shared skill. This article charts the methods behind both bodies of work so that photographers, curators, and educators can integrate them directly.
How the Mordache Association Turns Archives into Workshops
The association operates a physical study room in Lausanne where thirty thousand negatives are stored at 16 °C and 35 % relative humidity. Researchers must book a slot forty-eight hours in advance and are permitted to request no more than twelve folders per visit. Each folder comes with a printed condition report documenting scratches, silver mirroring, and previous retouching. These reports become teaching material: participants gain skills in reading deterioration patterns as evidence of earlier storage failures rather than artistic intent.
Workshop modules last three consecutive Saturdays. On day one the group studies contact prints under daylight-balanced LEDs; on day two they prepare 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 must justify one cropping decision using the original negative as reference. Attendance records show that eighty-four percent of participants later present at least one exhibition within eighteen months, implying the structured comparison accelerates curatorial confidence.
Picking Projects That Acknowledge Long-Term Observation
Del Curto rarely begins 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 captured 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 chart 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 present twenty images and a one-page calendar rather than a written proposal. Grants range from CHF 1 200 to CHF 2 400 and must be spent on film, chemistry, or travel within nine months. Recipients showcase work-in-progress at the association’s annual open house, where peers spot factual inaccuracies before prints reach the archive. This peer checkpoint cuts later caption revisions by roughly half.
Navigating Colour Shifts Over Different Print Runs
Even when negatives keep stable, paper emulsions alter over decades. The association maintains a reference set of Del Curto prints produced between 1987 and 1994, each matched with a spectrophotometer reading of the maximum black. New prints are calibrated to within ΔE 1.5 before they depart the darkroom. When an older paper stock is unavailable, the association issues the exact filtration change needed under the enlarger so that subsequent printers can compensate without guesswork. This documentation stops the cumulative drift that can distance an exhibition set from its archival reference within five years.
Digital scans intended for exhibition catalogues are generated at 800 dpi on a Hasselblad scanner rather than a flatbed, because drum scans bring Newton rings on fibre texture. Colour profiles are built from a custom target reproduced on the same paper batch employed for the final exhibition prints. The resulting ICC profile is saved alongside the negative so that any future catalogue can be made without re-scanning. The association estimates that preserving these profiles amounts to CHF 180 per exhibition but eliminates colour-correction costs at the printing stage.
Understanding Mario Del Curto’s Characteristic Photographic Language
Del Curto develops each series around a specific technical constraint that directs attention onto subject matter instead of equipment. In one project he confined himself to a single 50 mm lens and natural light for eighteen months, capturing daily rituals inside alpine farmhouses. The resulting contact sheets expose how consistent focal length modifies spatial relationships: door frames flatten into graphic lines, while faces gain proximity without distortion. Viewers come to understand to anticipate where the next frame will fall because the photographer’s stance stays predictable. This self-imposed rule shows that creative decisions often precede camera settings.
Colour in Del Curto’s prints is never decorative. He mixes his own selenium and sulphide toners, shifting cool shadows toward aubergine while leaving highlights neutral. The process needs three separate fixing baths and a final wash of forty minutes; any shorter and residual chemistry creates a green cast within five years. Workshops organised by the Mordache Association now teach the same toner formulas, permitting participants to copy the hue shifts on their own fibre papers. The measurable outcome is an growth in perceived depth, because the altered blacks separate more clearly from mid-tones under gallery lighting.
Instructing Observational Drawing to Enhance Photographic Decisions
The Mordache Association operates a parallel drawing course that meets every Tuesday evening. Participants devote twenty minutes sketching the same still-life before taking up a camera. The exercise forces attention to edge relationships that photographs often compress. After six weeks, students state that they pre-visualise cropping lines more exactly, reducing the number of exposures needed on location by roughly thirty percent. The association tracks these metrics through negative counts submitted with each assignment.
Drawing materials are limited to graphite and a single sheet of 300 gsm cotton paper per session. No erasers are accepted; instead, students must modify value by varying pressure. This constraint mirrors the irreversibility of exposure and promotes decisive mark-making. Several graduates have noted that the same pressure control later converts into more consistent burning and dodging under the enlarger, because finger sensitivity has already been tuned.
Long-term Printing Techniques That Maintain Subtle Detail
Fiber-based papers continue to be central since their baryta layer takes selenium toner without the micro-cracking apparent on resin-coated surfaces after twenty years. Del Curto’s chosen emulsion is a chloride-silver mix that achieves maximum density at grade 2½ under a cold-light head. When the same negative is printed on a grade 3 paper, shadow detail compresses by two zones on the Zone System scale, an effect he utilizes only when the subject holds specular highlights that would otherwise block up. The association’s darkroom log records exact paper batches and developer dilution, enabling future printers to reproduce identical tonal values.
Spotting is carried out with a 000 sable brush and diluted watercolour in place of dye-based retouching colours. Watercolour keeps matte under raking light, whereas dye mirrors and pulls attention to the correction. Trainees rehearse first on discarded test strips until the repair is imperceptible 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.
Developing Narrative Sequences from Single Images
Del Curto rarely exhibits individual frames. In contrast he constructs linear sequences in which each photograph supplies missing context for the next. In a project on seasonal cattle drives, image four depicts only a cow’s flank and a hand gripping a staff; image five expands to reveal the mountain path and the length of the herd. Viewers rebuild the missing geography because the earlier close-up has already established scale. The association prompts 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 composed after the sequence order is fixed, never before. Del Curto records factual details—breed, date, altitude—while an editor confirms 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.
Illumination Approaches for Interior Cultural Spaces
Numerous subjects Del Curto photographs cannot be moved 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, diminishing the ambient level by two stops while the flash, gelled to 3200 K, documents the colour of a copper pan exactly. The ratio between key and fill is assessed with an incident meter rather than depended on to histogram peaks, because JPEG previews often clip specular reflections on metal. Attendees in the association’s lighting module replicate the same measurement sequence until the ratio remains consistent across three different rooms.
Window light alone can be enough when exposure latitude is favoured 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 instructed to calculate the same ratio on their phones using a reflected-light app before pressing the shutter, teaching them to anticipate tonal compression without a meter.
Appraising Exhibition Spaces for Optimal Perceptual Impact
Del Curto’s prints are commonly 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 retains 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 accounting 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 stays 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 lined with archival foam that deforms 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 retrieve the log and validate that fluctuations stayed within ±2 °C and ±5 % RH. Any excursion triggers an acclimatisation period of forty-eight hours before unpacking. The protocol has cut visible print cockling to zero across twenty-three touring exhibitions since its introduction in 2016.
