Much has been said about the technical aspects of photography.
I'm being blunt when I say they're worth a damn.. in my book.
There is nothing like a bad photograph. In fact the scientific approach to defining art as good or bad - is not worth subscribing to. One mans art is another mans fart.
I may like a photograph or I may not - it's a binary state analysis.
If I do - then kudos to the artist.. else a few judo kicks in my mind. But I'm quite sure that someone somewhere will understand what was being depicted and appreciate it.
A few budding artists sent me a few photographs to see if I could help them out. Try I did.
But I believe that you do not need anyone else's appreciation to believe in yourself and your art.
It's quite simple actually.
Learn the technical aspects of photography - as you deem necessary to create the images that you would like to see. Don't over analyze your art to the point of making it a quantifiable entity. We all have our individual vision - even though many of us don't realize it (as yet). But we look at others and wish we could be like them. I'm not saying that having a role model is bad - but don't copy him/her in your art. Even if you do - make those subtle changes - those nuances in your form to ensure that you stand out by yourself.
Let your creativity define your art... rather than any individual and his art.
