Juxtaposition is a popular technique in photography. It involves placing objects close together for a contrasting effect. It can also been used to emphasize the subject and theme of your photo, as I’ve done in this picture of my daughter (the flower from last week).
Next time you take a photo, see if there’s a way to benefit from at least one contrasting element in the scene. Maybe there’s one or a few. Maybe there’s none. But the exercise will help you develop your eye for what’s going on in the scene. And that will help you become a better photographer.
