Ein Verfahren zur Erzeugung von Hochdynamikbereich-(HDR)-Bildern mit einem HDR-Kamerasystem (10) umfasst ein Aufnehmen einer Vielzahl von Kamerabelichtungen mit einer Kamera (20) des HDR-Kamerasystems, ein Erzeugen eines ersten HDR-Bilds (52A, 62A) aus einem ersten Unter-Satz der Vielzahl von Kamerabelichtungen, wobei jede Kamerabelichtung des ersten Unter-Satzes einen unterschiedlichen Belichtungswert aufweist, und ein Erzeugen eines zweiten HDR-Bilds (52A, 62A) aus einem zweiten Unter-Satz der Vielzahl von Kamerabelichtungen, wobei der zweite Unter-Satz zumindest eine Belichtung aus dem ersten Unter-Satz und zumindest eine zusätzliche Belichtung, die vor kürzerer Zeit als die Belichtungen des ersten Unter-Satzes aufgenommen wurde, umfasst, wobei jede Belichtung des zweiten Unter-Satzes einen unterschiedlichen Belichtungswert aufweist.

High helix, high mass-flow device and method

A method of forming a gas-liquid plume includes causing a gas to flow through helical conduits, and thereby causing the gas to swirl within a funnel-shaped volume of a connection component, and causing a liquid stream to flow into the funnel-shaped volume such that the liquid is broken up into droplets and ligaments by the gas within the funnel-shaped volume. The present disclosure also relates to the use of helical conduits with quadrilateral cross-sections to provide a high mass flow-rate and a desired swirling motion within a flow device. The present disclosure also relates to a method of assembling a device for forming a gas-liquid plume, including the steps of connecting a nozzle component to a connection component and, subsequently, connecting a main component to the connection component.
