Meaning: Lennart Nilsson, a renowned Swedish photographer, is best known for his groundbreaking work in capturing detailed images of biological specimens. His quote, "We sometimes freeze the specimen with liquid nitrogen, which is extremely cold, you know. This is another technique we use now - but the specimens are not alive," reflects his innovative approach to photography and his use of cutting-edge techniques to capture extraordinary images of living organisms.

In this quote, Nilsson highlights the use of liquid nitrogen as a method to freeze biological specimens. Liquid nitrogen is an extremely cold substance with a boiling point of -196 degrees Celsius (-321 degrees Fahrenheit). By immersing specimens in liquid nitrogen, they can be rapidly frozen, preserving their structure and preventing decay. This technique allows Nilsson to capture intricate details of the specimens with exceptional clarity and precision.

Nilsson's work with frozen specimens represents a departure from traditional photography, as he is not capturing live subjects. Instead, he is freezing and preserving specimens, enabling him to study and photograph them in unprecedented detail. This approach has allowed him to create captivating images that offer a unique perspective on the natural world.

By using liquid nitrogen to freeze specimens, Nilsson demonstrates a dedication to pushing the boundaries of photography and scientific imaging. His willingness to explore unconventional methods sets him apart as a pioneer in the field of biological photography. Through his innovative techniques, Nilsson has expanded the possibilities of what can be achieved through the lens of a camera, opening new doors for scientific exploration and artistic expression.

Nilsson's quote also underscores the ethical considerations involved in his work. By explicitly stating that the specimens are not alive, he acknowledges the importance of ethical treatment and responsible use of biological materials in his photography. This reflects his commitment to conducting his work with integrity and respect for the natural world.

Overall, Lennart Nilsson's quote encapsulates his pioneering spirit and dedication to pushing the boundaries of photography and scientific exploration. His innovative use of liquid nitrogen to freeze specimens has allowed him to capture extraordinary images that offer a glimpse into the intricate beauty of the natural world. Through his work, Nilsson has left an indelible mark on the fields of photography and science, inspiring others to push the limits of what is possible in capturing the wonders of the living world.
