Everything we hear is an opinion, not a fact. (Marcus Aurelius).
For years I have worried that I didn't have the certainty of opinion that me to say- this is how it is. I know I am right. I would envy those I worked with who carved a soapbox of stone right where they stood and didn't budge from their adopted position. How can the need to be 'right' more important than the need to listen, and learn, and even change? Nowadays I relish the thought that the little certainties of life are constantly challenged. In photography, especially. Vignetting? Bring it on. A bit of grain? Love that. Focus, schmocus. There are no rules. On my (expensive) camera I have placed the (relatively cheap) little plastic, selective focus lens, my Lensbaby, (never was a lens more aptly named) and once again I am looking at the world with a different perspective. The focus of life will fall where you choose.
