I have found that it is best to let the idea of a photo find me. When I set out with a certain idea in mind the photos never come out the way I had imagined them to be. The preconceived notion stifles the free flow of the 'what if' during the shooting time.
My favorite photos are of the scenes I happen to see and then shoot right away. There was no way to foresee or prepare for the above photo. I have a new lens -- the Lensbaby Composer Pro with the Sweet 35 optic. So far I love it more than my old Composer. When the lens arrived, I put it on my old Rebel and left it there -- so if I see something around the house -- like Sadie napping -- I can grab it and play around.
Last Saturday I went along on a workshop at the McIntosh Preserve in Whitesburg, GA -- on the Chattahoochee River. Beautiful day -- and yep -- I took along the newest Lensbaby. My subject matter changes almost daily. Whatever I see that I like -- I shoot it. I am a promiscuous photographer. I am not held tightly to any one type of subject. I love the dogs, nature, still life, or city scenes.
I believe this promiscuity comes from being in a photography club or group. When you have a monthly theme to shoot for -- you look outside of your normal routines. Seeing the photos that other people bring in will also open your eyes to things you may not have thought about before. Recently I began leading a new group connected to the Serenbe Photography Center. If you are in the area, and looking for a group -- come check us out.
