My career is based primarily upon finding a balance with a director and their vision, and that means sublimating my own personal ego toward their material.
Sadly, cinemas with film as the primary source are disappearing. We need to remain open to change. That does not require one to divorce the past but to respect and process both the present and the future.
During a movie, you lose all ability to focus on your own interests. Your life is in service. After that you just want to disappear, switch off the phone, and sleep and watch movies for a month.
I have developed my eye as a cinematographer through the craft of operating. When I am not operating, I am often anxious, uncertain, restless, sometimes irritable. When I am in the position of working with Steadicam or remote cameras, I fly with a broken wing.
