Born in 1996 in Paris, Sidonie Ronfard is a photographer and visual artist, and a graduate of ENSAD (Photography & Video department). In 2019, she was awarded the Prix de la Jeune Photographie Européenne and exhibited her work in Paris alongside the other laureates. That same year, she joined the Master of Photography program at Aalto University in Finland.

In 2022, Sidonie took part in an artist residency aboard the vessel Marion Dufresne in collaboration with IFREMER, marking her first exploration into the convergence of art and science.

In 2023, she was a finalist for the Prix AMMA (Contemporary Art Prize), an achievement marked by the exhibition of her work Emotional Overlap II at the Bastille Design Center in Paris.

In 2024, she presented her first solo exhibition, Turbulences, at the Chapelle des Carmélites in Toulouse. Produced as part of the Résidence 1+2 Factory #14 x CIMI, the project explored uncertainty through the lens of perception, transformation and scientific observation. Her research was also presented during the Photographie & Sciences symposium at the Musée des Abattoirs alongside the four laureates of the 2024 Résidence 1+2.

Her practice spans photography, installation, moving image and self-publishing, which she approaches as a tactile extension of the photographic experience. Working with analogue processes, image transfers and material transformations, she investigates the unstable nature of perception and the ways images emerge, shift and dissolve. Through observations of natural phenomena such as condensation, reflection, diffraction and thermal change, her work explores the threshold between the visible and what escapes immediate perception. Heat often appears as a recurring motif ; at once a physical force and a metaphorical one ; evoking both environmental transformations and inner states of tension, fever and burning. Her work inhabits this space where climatic and intimate disturbances become entangled, revealing the fragile conditions through which images, bodies and landscapes are continuously transformed.
