Mario Del Curto’s photographs and the work of the Mordache Association together build a living archive of how images can capture, interpret, and preserve cultural practices that might otherwise fade https://mariodelcurto.ch/. Readers looking for practical guidance on visual storytelling will uncover practical lessons in the way Del Curto captures a single gesture or notes 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 outlines the methods behind both bodies of work so that photographers, curators, and educators can adapt them directly.
Understanding Mario Del Curto’s Characteristic Photographic Language
Del Curto constructs each series around a narrow technical constraint that directs attention onto subject matter instead of equipment. In one project he restricted himself to a single 50 mm lens and natural light for eighteen months, documenting 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 acquire proximity without distortion. Viewers learn to anticipate where the next frame will fall because the photographer’s stance stays predictable. This self-imposed rule demonstrates that creative decisions often anticipate camera settings.
Colour in Del Curto’s prints is not decorative. He mixes his own selenium and sulphide toners, shifting cool shadows toward aubergine while keeping highlights neutral. The process requires three separate fixing baths and a final wash of forty minutes; any shorter and residual chemistry produces a green cast within five years. Workshops organised by the Mordache Association now instruct the same toner formulas, allowing 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.
Managing Colour Shifts Over Different Print Runs
Although negatives stay stable, paper emulsions change over decades. The association preserves a reference set of Del Curto prints made between 1987 and 1994, each paired with a spectrophotometer reading of the maximum black. New prints are matched to within ΔE 1.5 before they depart the darkroom. When an older paper stock is no longer available, the association issues the exact filtration change needed under the enlarger so that subsequent printers can correct 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 generated at 800 dpi on a Hasselblad scanner rather than a flatbed, because drum scans create Newton rings on fibre texture. Colour profiles are constructed 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 created without re-scanning. The association calculates that keeping these profiles contributes CHF 180 per exhibition but eradicates colour-correction costs at the printing stage.
Choosing Projects That Reward Long-Term Observation
Del Curto rarely starts with a predetermined narrative. Instead he pinpoints 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 recorded the incremental replacement of each beam, the arrival of new tools, and the gradual change in workers’ clothing. The sequence now acts 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 extend 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 flag factual inaccuracies before prints reach the archive. This peer checkpoint reduces later caption revisions by roughly half.
Instructing Observational Drawing to Improve Photographic Judgments
The Mordache Association conducts 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 drives attention to edge relationships that photographs often compress. After six weeks, students indicate that they pre-visualise cropping lines more accurately, 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 mirrors the irreversibility of exposure and promotes 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.
The manner in which the Mordache Association Converts 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 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 includes a printed condition report noting scratches, silver mirroring, and previous retouching. These reports serve as 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 insert 4×5 film holders and match 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 indicate that eighty-four percent of participants later organize at least one exhibition within eighteen months, indicating the structured comparison accelerates curatorial confidence.
Historical Printing Processes That Retain Subtle Detail
Fiber-based papers stay central since their baryta layer takes selenium toner free of the micro-cracking apparent on resin-coated surfaces following 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 uses only when the subject includes 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 carried out with a 000 sable brush and diluted watercolour rather than dye-based retouching colours. Watercolour stays matte under raking light, whereas dye mirrors and attracts attention to the correction. Trainees train first on discarded test strips until the repair is undetectable at 50 cm. The association calculates that a skilled printer can spot an 8×10 inch fibre print in forty-five minutes once muscle memory is developed.
Lighting Strategies for Cultural Interiors
Numerous subjects Del Curto photographs cannot 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 positions the flag to cut bounce from a whitewashed wall, diminishing the ambient level by two stops while the flash, gelled to 3200 K, records 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. Members in the association’s lighting module replicate the same measurement sequence until the ratio holds consistent across three different rooms.
Window light alone may suffice when exposure latitude is emphasised over colour temperature. Del Curto’s series on bread ovens was shot at 1/4 second on a tripod, using 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 triggering the shutter, coaching them to anticipate tonal compression without a meter.
Constructing Narrative Sequences from Individual Images
Del Curto seldom exhibits standalone frames. Instead he constructs 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 expands 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 records 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 required for any portfolio that receives association endorsement.
Assessing Exhibition Spaces for Peak Perceptual Impact
Del Curto’s prints are regularly shown at 1.5 times the diagonal of the negative. An 8×10 inch negative therefore generates a 15×18 inch print, a ratio that retains grain structure while enabling 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 stays legible at two metres. These specifications are released in the association’s technical rider so that host venues can replicate conditions without negotiation.
Transport crates are fitted with archival foam that squeezes no more than 3 mm under the weight of a framed 30×40 inch print. Each crate contains a data logger that logs 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 initiates an acclimatisation period of forty-eight hours before unpacking. The protocol has lowered visible print cockling to zero across twenty-three touring exhibitions since its introduction in 2016.
