MY PHOTO JOURNEY Sophistication (Mastery)

A quick summary of the main theories of photography…

Ariella Azoulay (2008) shifted attention from the photographer to the social relation created by the photograph. In The Civil Contract of Photography, she argues that photographs involve photographed people, photographers, and viewers in a civic relation. Viewers therefore have duties, not just feelings, when faced with images of harm or injustice.

Roland Barthes (1981) treated photography as a problem of meaning, memory, and loss. In Camera Lucida, he distinguishes between the studium, the broad cultural interest of a photograph, and the punctum, the detail that wounds or pierces the viewer. He also argues that every photograph carries the trace of “that-has-been”: the subject once stood before the camera, and this gives photography its stark link with time, death, and evidence.

Geoffrey Batchen (1997) questioned simple origin stories about the “invention” of photography. He argued that photography was desired before it was technically fixed, and that its history involves science, philosophy, culture, and longing, not just a list of inventors and processes.

Walter Benjamin (1936) argued that photography changed art by breaking the tie between an image and its unique time and place. Mechanical reproduction weakens the “aura” of the original, but it also makes images more public, mobile, and political. This is central to later debates about mass media, propaganda, and the loss of artistic authority.

John Berger (1972) developed Benjamin’s point for the age of mass media. In Ways of Seeing, he argued that images do not carry fixed meanings. Their meanings shift when they move into books, adverts, television, galleries, or private use. He also stressed that looking is shaped by class, gender, power, and prior belief.

Victor Burgin (1982) brought semiotics, Marxism, and psychoanalysis into photography theory. He treated photographs as signs within wider systems of language, desire, ideology, and viewing. For Burgin, a photograph does not merely show the world; it joins social codes that teach us how to read it.

Henri Cartier-Bresson (1952) gave photography one of its most famous practical ideas: the “decisive moment”. For him, the photographer must recognise the instant when form, gesture, meaning, and movement briefly cohere. His theory is less textual than practical. It stresses patience, timing, composition, and visual instinct, while treating the small handheld camera as a tool for alert, mobile attention.

Vilém Flusser (1983) treated the camera as an “apparatus” that shapes what can be made. His key point was that photographers do not simply express themselves through cameras; they also play within programmes built into technical systems. This has become more useful in the age of phones, platforms, presets, and AI.

Rosalind Krauss (1982) challenged the neat placement of photography within art history. She stressed photography’s indexical quality – its physical trace of what stood before the camera – but also argued that photographs work within different “discursive spaces”, such as science, survey, archive, gallery, or art market.

Martha Rosler (1981) gave one of the sharpest critiques of documentary photography. She argued that liberal documentary can turn poverty and pain into moral display for privileged viewers. Her point was not that documentary should end, but that it must confront power, class, authorship, and the uses to which images are put.

Allan Sekula (1986) attacked the idea that photographs speak for themselves. He argued that photographs gain meaning through archives, captions, institutions, police systems, labour, and state power. His work matters because it links photography to class, work, bureaucracy, and social control.

Susan Sontag (1979) argued that photography shapes how modern people see, consume, and judge the world. In On Photography, she claims that cameras turn experience into images and can make suffering, beauty, war, poverty, and travel available for repeated viewing. Her concern is ethical as well as cultural: photographs can sharpen moral attention, but they can also dull it by turning pain into spectacle or habit.

John Szarkowski (1966) gave photography a formal language. In The Photographer’s Eye, he framed photography around the thing itself, the detail, the frame, time, and vantage point. His key point was that photographs have their own visual grammar, not just a weaker version of painting.

Risks to construction workers from PFAS-contaminated soil (DRAFT)

Public concern about PFAS pollution often centres on drinking water, streams, rivers, and household exposure. This focus is understandable, but it can miss a key group: workers who disturb contaminated ground.

On construction sites, soil, ‘made ground’, sediment, concrete dust, drainage material, and groundwater may all become sources of direct exposure. Where a site has a history of firefighting foam use, aircraft activity, fuel handling, military use, or fire-training, PFAS risk is not a remote public health issue. It has to be treated as an occupational health issue.

Workers can encounter PFAS not through drinking local water, but through daily contact with contaminated soil and dust. During excavation, trenching, piling, landscaping, spoil movement, and waste handling, buried material can reach the surface. Dry soil can become dust. Wet soil can become mud. Both can be carried on gloves, boots, tools, vehicles, phones, and work clothes.

The main likely routes of exposure are hand-to-mouth transfer, inhalation of dust, skin contact with contaminated mud or water, and poor separation between dirty work zones and welfare areas. These pathways matter because construction work can involve repeated low-level exposure across long shifts and over many weeks or months. Research on PFAS and occupational exposure shows that workers who handle PFAS or PFAS-contaminated materials can have higher exposure than the general public (Christensen et al., 2023). Firefighter studies are also relevant because they show that PFAS from firefighting foam and related materials has become an established occupational concern (Graber et al., 2021; Hossain et al., 2023).

Previous PFAS cases show why a precautionary stance is justified. PFAS contamination linked to defence and airfield use has led to major legal, clean-up, and public health disputes in the United States and Australia. In Australia, defence-base contamination has led to large-scale remediation costs and legal claims linked to historic firefighting foam use. These cases show a common pattern: contamination can remain hidden or underplayed for years, while affected workers and residents carry the uncertainty and risk.

The importance of union involvement

Union involvement is particularly relevant because construction workers often lack the power, information, or security needed to challenge unsafe practice. Subcontractors, agency staff, and migrant workers often face added pressure to keep working even when site risks seem unclear.

Trade unions can press for a proper Construction Worker PFAS Risk Assessment; demand soil, dust, groundwater, sediment, and spoil testing; clear site briefings; dust control; clean and dirty zones; suitable PPE; handwashing and welfare facilities; waste controls; and independent review of risk assessments.

UK health and safety law already gives worker representatives a role in raising such concerns. The Health and Safety Executive states that hazardous substances in construction include dusts and other harmful substances, and that health and safety representatives have legal functions in the workplace (Health and Safety Executive, 2024, 2025). In this context, union involvement is not an intrusion. It is a practical safeguard for the people most likely to disturb, breathe, handle, and transport contaminated ground before the wider public sees the finished development.
