Film Heritage Foundation used the best surviving elements for the restoration – the original camera negative and the 35 mm print preserved at the NFDC – NFAI. Unfortunately, the sound negative was not available. We digitized the sound from the 35 mm print preserved at Film Heritage Foundation. The film elements were repaired by the Film Heritage Foundation conservators and the scanning was done in Prasad Lab in Chennai We found that due to the deterioration of the print, there were vertical green lines on many parts of the film. While the scanning and digital clean-up was done at Prasad under the supervision of L’Immagine Ritrovata in Bologna, the grading, sound restoration and mastering was done at the lab in Bologna. Both Shyam Benegal and Govind Nihalani, the cinematographer of the film, have been involved in the restoration of the film.
