Interesting how a seemingly simple question generates such a complex set of answers.
I'm a little uneasy about the teachers' question : "Art, that’s special. What can you bring to it that nobody else can?"
Anyone can bring hard work, perseverance, and people skills to the table. Anyone has talent. No good being extra-special and original and out of the box if nobody recognises the quality of the work : good photography balances precariously on a thin line between 'Wow, I haven't seen this like that before' and 'This is exactly how that should look like', a dance between shape and content, recognition being the central node. One has to 'recognise' a photograph to want to explore it further.
To confuse the issue, recognition is the term associated with fame, name-recognition.
This is unfortunate, as fame has little coincidence with artistic merit. For every Van Gogh there are tens, maybe hundreds of painters who are just as interesting. Vivian Maier is one name that popped out of obscurity posthumously. How many others are there? How many others were there, with a camera and something to shoot?
If the question is about 'making art', talent is a given, hard work and perseverance are required. you need to be obsessed with taking photographs, and obsessed with taking better ones.
If the question is about 'making it', it's mostly luck. Like being a friend of the drummer in a group that turns out big, or getting introduced to the editor of Vogue, or going viral on social media with a complaint about how hard the life of a photographer is.
In answer to the teacher in the movie : art isn't all that special. It's just a name for a better class of craftsmanship.
