Mario Del Curto’s photographs and the work of the Mordache Association together build a dynamic archive of how images can record, interpret, and sustain 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 composes a single gesture or notes the texture of a wall. The Mordache Association expands this approach by matching archival prints with community workshops, transforming 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.
Managing Colour Shifts Across Various Print Runs
Even when negatives remain stable, paper emulsions shift over decades. The association keeps 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 publishes the exact filtration change needed under the enlarger so that subsequent printers can correct without guesswork. This documentation stops the cumulative drift that can distance an exhibition set from its archival reference within five years.
Digital scans meant for exhibition catalogues are produced at 800 dpi on a Hasselblad scanner rather than a flatbed, because drum scans bring Newton rings on fibre texture. Colour profiles are constructed from a custom target produced 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 created without re-scanning. The association reckons that preserving these profiles contributes CHF 180 per exhibition but eradicates colour-correction costs at the printing stage.
Developing Narrative Sequences from Single Images
Del Curto rarely exhibits standalone frames. Rather he assembles linear sequences in which each photograph offers 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 broadens 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 written 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 required for any portfolio that receives association endorsement.
Long-term Printing Processes That Preserve Subtle Detail
Cellulose-based papers remain central as their baryta layer takes selenium toner without the micro-cracking apparent on resin-coated surfaces past twenty years. Del Curto’s favourite 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 exploits only when the subject holds specular highlights that would otherwise block up. The association’s darkroom log notes exact paper batches and developer dilution, allowing future printers to duplicate identical tonal values.
Spotting is executed with a 000 sable brush and diluted watercolour rather than dye-based retouching colours. Watercolour stays matte under raking light, whereas dye reflects and attracts attention to the correction. Trainees practise first on discarded test strips until the repair is undetectable at 50 cm. The association estimates that a skilled printer can spot an 8×10 inch fibre print in forty-five minutes once muscle memory is established.
The manner in which the Mordache Association Turns Archives into Workshops
The association maintains 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 may 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 turn into teaching material: participants are taught to interpret deterioration patterns as evidence of earlier storage failures rather than artistic intent.
Workshop modules run for three consecutive Saturdays. On day one the group examines 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 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, indicating the structured comparison boosts curatorial confidence.
Understanding Mario Del Curto’s Characteristic Photographic Language
Del Curto builds each series around a narrow technical constraint that pushes attention onto subject matter rather than equipment. In one project he restricted himself to a single 50 mm lens and natural light for eighteen months, capturing 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 acquire proximity without distortion. Viewers begin to see 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, transitioning cool shadows toward aubergine while leaving 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 arranged 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 rise in perceived depth, because the altered blacks distinguish more clearly from mid-tones under gallery lighting.
Instructing Observational Drawing to Enhance Photographic Decisions
The Mordache Association conducts a parallel drawing course that gathers every Tuesday evening. Participants allocate twenty minutes sketching the same still-life before grasping a camera. The exercise drives attention to edge relationships that photographs often compress. After six weeks, students state that they pre-visualise cropping lines more accurately, 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 restricted to graphite and a single sheet of 300 gsm cotton paper per session. No erasers are allowed; instead, students must alter value by varying pressure. This constraint echoes the irreversibility of exposure and promotes decisive mark-making. Several graduates have remarked that the same pressure control later translates into more consistent burning and dodging under the enlarger, because finger sensitivity has already been calibrated.
Selecting Projects That Reward Long-Term Observation
Del Curto rarely begins 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 captured the incremental replacement of each beam, the arrival of new tools, and the gradual change in workers’ clothing. The sequence now serves 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 comes through the association’s micro-grant programme. Applicants submit 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 note factual inaccuracies before prints reach the archive. This peer checkpoint reduces later caption revisions by roughly half.
Illumination Approaches for Indoor Cultural Venues
Several subjects Del Curto photographs cannot be relocated 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, lowering 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 gauged with an incident meter rather than relied upon 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 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 shot at 1/4 second on a tripod, utilising only north-facing windows at 10 a.m. The resulting negatives preserve 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 triggering the shutter, coaching them to anticipate tonal compression without a meter.
Appraising Exhibition Spaces for Maximum 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 preserves grain structure while permitting 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 printed in the association’s technical rider so that host venues can duplicate conditions without negotiation.
Transport crates are covered with archival foam that compresses no more than 3 mm under the weight of a framed 30×40 inch print. Each crate contains a data logger that tracks temperature and humidity every fifteen minutes. Upon arrival the receiving venue must download the log and validate 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.
