“Experts say that there’s no better time to be different, so don’t concern yourself too deeply with what will ‘sell,’ or try to adapt your individual style into something that’s more commercial or mainstream.”
Demetrius Fordham (via Jorge Quinteros)
This is meant for professionals, but applies to amateur photographers just as well. As I wrote in the book: be remarkable, not marketable.
Oh, and there are no “experts.”
