I was surfing around National Geographic and found this nifty extract:
"Desire and drive count, but professional photography is a competitive business, and for every successful photographer there are dozens looking for work. Training can only help to fine-tune a natural "eye," and although a prospective photographer may have a true passion for the art and craft, if he lacks that eye no amount of training or desire can compensate. Many people must be content to be advanced amateurs rather than professionals."
I ask myself the same question... do I have an "eye" or not for good photography... probably would be too bold and arrogant to say tha
