Mario Del Curto’s photographs and the work of the Mordache Association together build a dynamic archive of how images can document, explain, and sustain cultural practices that might otherwise diminish https://mariodelcurto.ch. Viewers seeking practical guidance on visual storytelling will find useful lessons in the way Del Curto composes a single gesture or notes the texture of a wall. The Mordache Association builds on this approach by pairing archival prints with community workshops, converting private observation into shared skill. This article charts the methods behind both bodies of work so that photographers, curators, and educators can adapt them directly.
Del Curto’s prints are routinely 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 enabling viewers to stand at conversational distance. When the association installs work, it gauges 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 printed in the association’s technical rider so that host venues can reproduce conditions without negotiation.
Transport crates are covered with archival foam that deforms no more than 3 mm under the weight of a framed 30×40 inch print. Each crate holds a data logger that records temperature and humidity every fifteen minutes. Upon arrival the receiving venue must access the log and confirm 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.
Del Curto rarely begins with a predetermined narrative. Instead he identifies 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 arrives 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 present work-in-progress at the association’s annual open house, where peers spot factual inaccuracies before prints reach the archive. This peer checkpoint reduces later caption revisions by roughly half.
The Mordache Association operates a parallel drawing course that meets every Tuesday evening. Participants allocate twenty minutes sketching the same still-life before taking up a camera. The exercise drives attention to edge relationships that photographs often level. After six weeks, students report that they pre-visualise cropping lines more exactly, reducing the number of exposures needed on location by roughly thirty percent. The association monitors these metrics through negative counts provided with each assignment.
Drawing materials are confined to graphite and a single sheet of 300 gsm cotton paper per session. No erasers are permitted; instead, students must alter value by varying pressure. This constraint mirrors the irreversibility of exposure and encourages decisive mark-making. Several graduates have observed that the same pressure control later carries over into more consistent burning and dodging under the enlarger, because finger sensitivity has already been calibrated.
Even when negatives keep stable, paper emulsions change over decades. The association maintains a reference set of Del Curto prints made between 1987 and 1994, each accompanied by a spectrophotometer reading of the maximum black. New prints are aligned to within ΔE 1.5 before they leave the darkroom. When an older paper stock is no longer available, the association issues the exact filtration change necessary under the enlarger so that subsequent printers can compensate without guesswork. This documentation stops the cumulative drift that can divide 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 create Newton rings on fibre texture. Colour profiles are developed from a custom target printed on the same paper batch utilized for the final exhibition prints. The resulting ICC profile is stored alongside the negative so that any future catalogue can be produced without re-scanning. The association calculates that preserving these profiles contributes CHF 180 per exhibition but eliminates colour-correction costs at the printing stage.
Many subjects Del Curto photographs are unable to be moved to a studio. He consequently 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 depended on 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 remains consistent across three different rooms.
Window light alone may suffice when exposure latitude is favoured over colour temperature. Del Curto’s series on bread ovens was captured at 1/4 second on a tripod, employing 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 went beyond 5:1. Students are required to calculate the same ratio on their phones using a reflected-light app before releasing the shutter, coaching them to anticipate tonal compression without a meter.
The association maintains 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 noting 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 studies contact prints under daylight-balanced LEDs; on day two they prepare 4×5 film holders and reproduce Del Curto’s exact tripod height for an assigned interior. The final session is a group critique in which every participant is required to explain one cropping decision using the original negative as reference. Attendance records show that eighty-four percent of participants later mount at least one exhibition within eighteen months, suggesting the structured comparison accelerates curatorial confidence.
Del Curto infrequently exhibits individual frames. Rather he builds linear sequences in which each photograph supplies missing context for the next. In a project on seasonal cattle drives, image four shows 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 encourages 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 records factual details—breed, date, altitude—while an editor verifies 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 mandatory for any portfolio that receives association endorsement.
Fiber-based papers stay central since their baryta layer takes selenium toner lacking the micro-cracking visible on resin-coated surfaces past twenty years. Del Curto’s favourite emulsion is a chloride-silver mix that attains maximum density at grade 2½ under a cold-light head. When the same negative is printed on a grade 3 paper, shadow detail reduces 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, allowing future printers to reproduce identical tonal values.
Spotting is carried out with a 000 sable brush and diluted watercolour instead of dye-based retouching colours. Watercolour keeps matte under raking light, whereas dye throws back and pulls attention to the correction. Trainees train 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.
Del Curto constructs each series around a strict technical constraint that forces 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, recording daily rituals inside alpine farmhouses. The resulting contact sheets reveal how consistent focal length alters spatial relationships: door frames squeeze into graphic lines, while faces achieve 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 illustrates that creative decisions often anticipate camera settings.
Colour in Del Curto’s prints is never decorative. He blends his own selenium and sulphide toners, shifting cool shadows toward aubergine while maintaining highlights neutral. The process requires three separate fixing baths and a final wash of forty minutes; any shorter and residual chemistry creates a green cast within five years. Workshops arranged by the Mordache Association now teach the same toner formulas, allowing participants to reproduce the hue shifts on their own fibre papers. The measurable outcome is an rise in perceived depth, because the altered blacks distinguish more clearly from mid-tones under gallery lighting.
