While on a photo walk in Wicker Park (Chicago), I couldn't help but pause and photograph this scene. I just loved the way the yellow leaf had landed on the chess table. That, combined with the overcast morning, really gave this scene a distinctive mood and feel. I know that my 85mm lens is a champ at capturing subtle colors and light, so I put that on, opened the aperture all the way, and shot.
Having an intimate knowledge of one's lenses--understanding their strengths as well as their limitations--opens up new creative worlds. It gives us the opportunity to make choices that with help to improve our work. It's just as much a part of the artistic process as composition and subject choice.
