If you are aware, opportunities for the creation of something visually interesting often present themselves. You don't have to seek them out. Just be there and push the shutter button. Monica and I had just finished lunch with friends and were walking back to our car when I spotted this composition. It was taken in an alley around 2 P.M. with the sun high in the sky and the subject matter features a bent steel handrail and a shadow of a walkway on the back of an old building. So much for the idea that "good light" and compelling subject matter are necessary for a successful image.
There are great images waiting to be created all around us. Learn to look for them. You might find your next one in an alley or a parking garage.
