Via Models.com I was led to photographer Rodney Smith's blog where he had this to say about photography and vision:
To say a photographer has a vision is to say the photographer has something unique to say to about the world. Why do some photographers have something unique to say, when so many others just shoot pictures that are general and lacking vision? Most people would say it has to do with talent. Maybe. But maybe not. Maybe it has nothing to do with talent. Maybe it has to do with the ability to express one’s feelings. The person who presents a strong vision has figured out a way to express his or her feelings, while others are struggling to do that. Talent, then, becomes not so much artistic talent, though that may be a good part of it, but rather emotional talent.
And take a look at some of his pictures at his website. Here are some to show you just a glimpse of the genius this guy is!
