Personal life
Tirru was born on 21 July 1966 in Mullukuruchi village, Namakkal. He became interested in photography while studying science in college. He assisted by his cousin, a dentist by profession, in the latter's passion for nature photography.

Film career
He co-wrote the screenplay of the Malayalam film Mission 90 Days with director Major Ravi. He is also known for television commercials.

Debut as cinematographer (1993)
Tirru learnt the craft of cinematography by assisting cinematographer P. C. Sreeram for over four years. He gained recognition during the filming of Thevar Magan (1992), drawing the attention of Kamal Haasan. Consequently, Tirru was enlisted to be the cinematographer of director Singeetam Srinivasa Rao's Magalir Mattum (1994), a project backed by Kamal Haasan. Srinivasa Rao wasn't used to working with newcomers and had doubts at first but Tirru convinced him with his technical skills in the opening shots. Kamal Haasan's faith in Tirru played a big role in this success. During the filming of KT Kunjumon's Tamil movie Sakthi in 1997, the shoot was set in Pollachi. In one particular scene featuring charging wild elephants, Tirru and his assistant were on a 45-foot-high crane to shoot a scene. Unfortunately, the situation took a dangerous turn as still photographer Rajesh recounts, "Somehow, the mahouts lost control of the elephants, and they came charging towards the crane. We knew that if they hit the crane, we would fall to our deaths." to Cinema Express.

Collaboration with Kamal Haasan (1993–2001)
Early in his career, Tirru and Kamal Haasan has collaborated on four films, Magalir Mattum (1994), Kaathala Kaathala (1998), Hey Ram (2000) and Aalavandhan (2001). Aalavandhan pioneered the use of a motion control rig in India for capturing picture movement and Tirru was the first cinematographer to introduce it. Aalavandhan was also the first film to use animation sequences in the Indian film industry.

Post national award (2018–present)
In 2018, Karthik Subbaraj reached out to Tirru for the silent film Mercury as he wanted an experienced cinematographer capable of conveying a narrative without relying on dialogue. They worked on the pre-production planning for three months to address the challenges posed by the film's silent nature and unconventional genre.

In 2019, Tirru and Karthik Subbaraj collaborated again on the action-drama film Petta starring Rajinikanth. This was Tirru's first collaboration with Rajinikanth and it was a long-held dream of his as he had missed an opportunity previously to be the cinematographer of Enthiran (2010) directed by Shankar.

Tirru debuted in Kannada cinema with the action thriller Twenty One Hours (2022) directed by debutant Jaishankar Pandit. Jai Sankar has worked with Tirru on multiple television advertisements.
