I just graduated Columbia with a concentration in Cinematography. The program is very intense, but the faculty instruction is fantastic and your opportunities to get on set are numerous. Since you are entering as a junior I would suggest starting your Cinematography Concentrated courses immediately so you can get the most out of your time in college. You can get some serious experience and great looking footage of your own if you carefully plan your courses. If you decide to enroll and have any questions about what courses to take or which instructors to talk to(guidance/advising from CINEMATOGRAPHY faculty, not your college advisor, is essential for transfer students) please don't hesitate to message me. I'd be happy to answer any questions you have or refer you to the proper people to make sure you get the most out of your time at Columbia.
