Ask yourself, what is the difference between a famous photographer and an unknown one?
15 years ago did you know who Vivan Maier was? Why had you never heard of this now famous photographer?
It is all about marketing. The difference between a famous photographer and an unknown one is not about the quality of their art (not always) but about the people who get to see their work. Yes the dirty word in the art world, marketing. But in order to share your work, and have people know your passion you will need to market. Don’t be afraid to market your work. Professional, or hobbyist you need to market what you love in order to share your passion.
