Mario Del Curto’s photographs and the work of the Mordache Association together form a dynamic archive of how images can record, explain, and preserve cultural practices that might otherwise fade https://mariodelcurto.ch/. Audiences looking for practical guidance on visual storytelling will discover actionable 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 outlines the methods behind both bodies of work so that photographers, curators, and educators can apply them directly.
Evaluating 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 produces a 15×18 inch print, a ratio that retains grain structure while permitting 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 offsetting 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 fitted with archival foam that compresses 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 retrieve 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.
Building Narrative Sequences from Individual Images
Del Curto infrequently exhibits individual frames. Instead he assembles 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 rebuild 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 written after the sequence order is fixed, never before. Del Curto states factual details—breed, date, altitude—while an editor verifies against meteorological records and village chronicles. Discrepancies are marked 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.
Selecting Projects That Acknowledge 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 map access permissions and seasonal light angles before committing to the first roll of film.
Funding for extended fieldwork often flows through the association’s micro-grant programme. Applicants send 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 display 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.
The manner in which the Mordache Association Transforms 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 must book a slot forty-eight hours in advance and can ask for no more than twelve folders per visit. Each folder comes with a printed condition report noting scratches, silver mirroring, and previous retouching. These reports turn into teaching material: participants learn to read deterioration patterns as evidence of earlier storage failures rather than artistic intent.
Workshop modules last three consecutive Saturdays. On day one the group inspects contact prints under daylight-balanced LEDs; on day two they prepare 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 must justify one cropping decision using the original negative as reference. Attendance records demonstrate that eighty-four percent of participants later present at least one exhibition within eighteen months, suggesting the structured comparison enhances curatorial confidence.
Instructing Observational Drawing to Strengthen Photographic Decisions
The Mordache Association operates a parallel drawing course that gathers 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 delivered 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 adjust value by varying pressure. This constraint mirrors the irreversibility of exposure and encourages 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 calibrated.
Navigating Colour Shifts Throughout Different Print Runs
Although negatives remain stable, paper emulsions alter 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 unavailable, the association issues the exact filtration change required under the enlarger so that subsequent printers can correct without guesswork. This documentation avoids the cumulative drift that can divide an exhibition set from its archival reference within five years.
Digital scans meant for exhibition catalogues are created 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 printed on the same paper batch used 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 reckons that keeping these profiles contributes CHF 180 per exhibition but eradicates colour-correction costs at the printing stage.
Historical Printing Processes That Retain Subtle Detail
Cellulose-based papers continue to be central because their baryta layer takes selenium toner without the micro-cracking visible on resin-coated surfaces after twenty years. Del Curto’s preferred 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 utilizes only when the subject includes specular highlights that would otherwise block up. The association’s darkroom log documents 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 instead of dye-based retouching colours. Watercolour keeps matte under raking light, whereas dye reflects and attracts attention to the correction. Trainees practise 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.
Exploring Mario Del Curto’s Characteristic Photographic Language
Del Curto develops each series around a strict technical constraint that pushes attention onto subject matter as opposed to equipment. In one project he confined 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 flatten into graphic lines, while faces gain proximity without distortion. Viewers begin to see to anticipate where the next frame will fall because the photographer’s stance remains predictable. This self-imposed rule illustrates that creative decisions often come before camera settings.
Colour in Del Curto’s prints is never decorative. He blends his own selenium and sulphide toners, moving cool shadows toward aubergine while maintaining highlights neutral. The process demands three separate fixing baths and a final wash of forty minutes; any shorter and residual chemistry creates a green cast within five years. Workshops hosted by the Mordache Association now teach the same toner formulas, allowing participants to copy the hue shifts on their own fibre papers. The measurable outcome is an rise in perceived depth, because the altered blacks separate more clearly from mid-tones under gallery lighting.
Lighting Strategies 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 positions the flag to cut bounce from a whitewashed wall, lowering 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 assessed 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 shot 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 exceeded 5:1. Students are instructed to calculate the same ratio on their phones using a reflected-light app before releasing the shutter, teaching them to anticipate tonal compression without a meter.
