The camerawork of the advertisement films impressed his former colleague and frequent collaborator, Gautham Vasudev Menon.
It was highly praised for its unique style of visuals and scenic views through the lens, which Rajasekhar achieved through a process known as Bleach bypass, where the silver is retained in the print, creating a washed-outlook that reflected in films.
In 2005, Rajasekhar began his collaboration with A. R. Murugadoss, which started with Ghajini.
Rajasekhar spent two months fine-tuning the look and de-saturating the overall images.
He reunited with A. R. Murugadoss for Akira (2016), the remake of Mouna Guru, having previously worked on Ghajini.
