Mark Klett is regarded as a pioneer of contemporary landscape photography because he transformed how photographers think about time, history, and change in the landscape. His greatest contribution is the development of rephotography—the practice of photographing the exact locations of earlier images to reveal how landscapes have evolved.

His pioneering reputation is based on several key achievements:

Pioneering rephotography

In the late 1970s, Klett led the influential Rephotographic Survey Project, relocating the viewpoints of 19th-century survey photographers such as Timothy O’Sullivan, William Henry Jackson, and Carleton Watkins. By making new photographs from the same positions, he created compelling visual comparisons that showed how the American West had changed over decades or even a century.

This approach has since become a widely adopted method in landscape photography, environmental studies, archaeology, and conservation.

Exploring time as a photographic subject

Rather than treating a photograph as a single, isolated moment, Klett demonstrated that photographs can form part of a much longer narrative. His paired images reveal the effects of natural processes, urban growth, tourism, conservation, and climate over time.

Challenging ideas of permanence

The landscapes of the American West were often portrayed as timeless and unchanging. Klett’s work showed that even iconic landscapes are constantly evolving, encouraging viewers to see change rather than permanence.

Blending art, history, and science

Klett’s projects combine artistic composition with historical research and precise fieldwork. He carefully identified the original camera positions and recreated them as accurately as possible, making his work valuable both as fine art and as historical documentation.

Innovative photographic techniques

Beyond straightforward rephotography, Klett experimented with diptychs, panoramas, and composite images that explored memory, perception, and the act of looking. These projects expanded the possibilities of landscape photography beyond simple documentation.

Influence on contemporary photography

Klett’s work has inspired photographers, historians, geographers, and environmental researchers around the world. Rephotography is now widely used to study glacier retreat, forest regeneration, coastal erosion, urban development, and the effects of climate change.

Why he is considered a pioneer

Mark Klett is considered a pioneer because he changed the way photographers use the medium to explore change through time. By revisiting historic viewpoints with exceptional precision, he demonstrated that photography can connect past and present in a uniquely powerful way. His work established rephotography as both an artistic practice and a rigorous tool for understanding landscapes, making him one of the most influential figures in modern landscape photography.

For someone interested in landscape photography, Klett’s work offers an important lesson: a landscape photograph need not simply depict a place—it can also reveal the passage of time, the marks of history, and the ongoing relationship between people and the environment.
