A simple example of a "measurement effect" is the quantum zeno effect [1]. You can steer a system by making a series of measurements and gradually transitioning the measurement axis from aligning with the initial state to aligning with the target state [2].
For example, placing a diagonal polarizer between a horizontal and vertical polarizer will allow light to pass through [3]. As you use more and more polarizers that gradually transition from horizontal to vertical, you converge on a mechanism for rotating horizontally polarized photons into vertically polarized photons without loss.
