In 2018 after using different still camera's for around 18-20 years Raju realizes that he is not good at photography. Photography requires a vision and an understanding of society, history, economics, politics and thus life with minute details. Going beyond technology is very tough. It requires systematic/non-systematic reading and thinking skills. If you ask Raju why did you shoot that blank wall? Raju is as blank as the wall.
The problem here is that cinema is also very similar.

NOW WHAT WILL RAJU DO?
