With a BSc in Physics and an international career in technology, Alva Martín builds a photographic practice at the intersection of digital immediacy and silent contemplation, engaging the debates at the heart of contemporary photography. He works almost exclusively with the mobile phone, the device through which most of us now live, combining scientific rigour with a poetic sensibility to ask how technology reshapes our relationships, our privacy, and the way we experience the world.

His central body of work is a long-term inquiry into self-surveillance, conceived in two movements. sentinel (2013– ) is the eye: an archive of more than eighty thousand images captured automatically by his own phone, an act of consented surveillance that turns the everyday device into a constant witness, and the data it gathers into vast, meditative fields of colour. eko is the ear: a decade of recorded phone calls in which the intimate voice becomes the trace it leaves on the one who was listening. Together they describe a world that has learned to watch itself, one where we surrender our privacy willingly, in exchange for connection and recognition. His most recent project, remanet (in progress), widens the lens to his entire photographic archive, hundreds of thousands of everyday images, asking what remains of a life of looking once it is compressed.

He complemented his education in 2022 with the Professional Photography Course at EFTI, and with the PHotoespaña Master's in Photographic Projects in 2024. His work has received notable recognition, including Finalist at Premios de Fotografía Fundación Enaire 2025, Nominee for Premios de Fotografía Fundación Enaire 2024 and the Official Selection of the International Photography Awards in 2025 & 2024, Nominee at the Fine Art Photography Awards (2024–2025 edition), Honorable Mention at the 1839 Awards 2024 and 2025, Official Selection, London International Creative Competition, LICC (2025), and being featured as one of Singulart's Spanish Artists to follow. His work has been published in Issue 30 of Dodho Magazine, September 2024, as well as in the books Portrait Awards 2025, Fine Art Awards 2024, Color Awards 2024, Monochromatic Awards 2024, Portrait Awards 2024 and Fine Art Awards 2023, all by Dodho Magazine.
