Establishing the period of a film can range from different techniques and approaches from natural candle lighting in Stanley Kubrick's Barry Lyndon and Sir Ridley Scott's meticulous naturalism in The Duellists. Eggers took notes from his predecessors and tried his best in transporting audiences to the late 19th century in The Lighthouse.
He went as far as recreating the era with the use of an aspect ratio of 1.19 - common of portrait cameras of the time.
