Right place, right time he has used his knowledge

My friend is in cine field. He is the assistant photographer, One day the director asked him to take that scene in bright light, but he is using his knowledge that scene will come beautiful only in the sun light. Without director knowledge he has taken that scene in sun light. In trial run, director asked him, what a fantastic lightning how it is possible, how you set that type of lighting, he appreciated by him when the same scene came. From that day onwards he is the main photographer to all his future films. Friend’s asked him how it is possible to come to a main photographer within a short period. He said this was happened only because of my knowledge gained at the time of working in Electronics shop.
