Motion is the phenomenon in which an object changes its position over time.
If an object is not changing relatively to a given frame of reference, the object is said to be at rest, motionless, immobile. There is no way to prove this. So, everything including humans are in constant motion.
There are four basic types of motion. These four are rotary, oscillating, linear and reciprocating. Each move in a slightly different way. Motion can include ‘slow, slight, moderate, gradual, steady, quick, rapid, significant, sharp, substantial, and dramatic’.
My motion images are both subject driven and/or in camera motion ICM. This motion quality creates an impressionistic sense of flow and movement.
