Academically speaking, reductivism is an art movement in sculpture and painting that began in the 1950's. It emphasized extreme simplification of form and color. Reductive images are often verging-on-abstract, reducing the literal context of the subject to a minimum, no longer relying on reality to please the eye. The same characteristics are found in images associated with Miksang, or contemplative photography.
This series of photos (below), through the use of selective focus, motion blur, composition, layered focal planes, or simple tight cropping, are all "reduced" to aesthetically pleasing images. The subjects no longer matter.
Your comments are welcome, and you are encouraged to explore more work by these photographers.
