Grammar Mistake in Pawan-Puri Title?

Power Star Pawan Kalyan's new movie title, 'Cameraman Gangatho Rambabu' is still haunting different sections of people for different reasons. This title received positive response from most of the Pawan Kalyan's fans and some class sections of general audience while the title has received mediocre response among the masses. 

As per the sources, it is understood that 'Ganga' in the title is none other than the heroine of the movie. Now, some of the educated people are arguing that, since 'Ganga' is declared the heroine, the movie's title should be 'Camerawoman Gangatho Rambabu', but not 'Cameraman Gangatho Rambabu', emphasizing the necessity of gender difference. However, some of the experts in English, are coming up with the dictionary meaning of 'Cameraman'. According to them Cameraman means, ' A person whose job is operating a camera for making films or T.V.programmes.' "Here 'A person' means, either a man or a woman. And so the title of the movie is grammatically correct.", They concluded.
